1.
Immediately following the internal blast cleaning, spray the inside of the pipe with Oakite
special protective oil using a low pressure non-atomizing solid spray to obtain an internal
protective coverage of 1400 to 1900 ft2/gal (34 to 47 m2/litre) or use corrosion protection
approved by the Owner. The following approved alternate methods may be used:
a.
Immediately following the internal cleaning, the inside of the pipe shall be sprayed
with a 4 percent solution of Shell Oil Company's VPI No. 250 or equal. This
product is a vapor phase inhibitor sold by Shell Oil Company in crystalline powder
form. The solution is prepared as follows:
•
•
•
1 lb VPI No. 250
2-1/2 gallons (9.5 litres) Isopropyl alcohol *
1/2 gallon (2 litres) water
Note: * Flammable; avoid prolonged breathing
Interior surfaces shall be thoroughly wetted with the solution. A minimum of 2
gallons (8 litres) for each 100 cubic feet (3 cubic meters) of internal volume shall
be used.
b.
VPI No. 250 may be applied in the crystalline powder form, as purchased. This
method requires blowing equipment to distribute it uniformly on the inside surface
of the pipe spool, applied in such a manner that no unprotected surface is more
than 12 inches (305 mm) from the powder. A minimum of 2 to 3 grams for every

operating volumetric flow rate. The system shall be blown initially at pressures near to
atmosphere in order to expel large objects from the system. Gradually raise the pressure
during later blows to the maximum operating pressure. The lines are to be blown for
more than 10 minutes and steam should only be blown from a clean piping system into
unclean systems. There shall be a minimum of 3 blows conducted. Between the blows
there should be a cool down period of at least 60 minutes for un-insulated piping systems
and 240 minutes for insulated piping systems or until the pipe surface temperature has
reached 212F (100°C). Additional requirement for steam lines to turbines include a
minimum of 15 blows shall be conducted. Use target plates of polished aluminium or
copper to determine cleanliness. Target plate recommended minimum size is 3 x 3 inches

Cleaning Procedure No 6: Passivation of Stainless Steel
A.
Scope of Procedure
This procedure covers the flushing, cleaning, and passivation of stainless steel piping systems
after assembly and erection.
B.
C.
Preparation for Cleaning Procedure
1.
Using P&IDs and other suitable piping diagrams, a detailed step-by-step plan will be
developed which describes the procedure for passivating the system. Particular care
should be exercised that the planning considers the heating of the solutions, acid addition
techniques, neutralization, and waste acid storage. This plan will be submitted to the
Owner for approval prior to the start of passivation.
2.
All pipe runs and joints will be visually inspected for proper installation and continuity.
3.
Equipment with restricted flow passages or inaccessible area where sediment could
collect shall either be bypassed or furnished with adequately sized temporary protection
strainers.
4.
If system pumps are to be used for flushing and do not have a permanent suction strainer,
they shall then have a temporary strainer installed between the suction valve and the
pump.
The temporary strainer shall be as specified in Project Specification
000.250.50003, according to individual line class.
5.
Where flushing water is re-circulated and not wasted to sewers, temporary strainers
and/or baskets will be installed at all sumps, tanks, and other accessible areas where
extraneous material flushed from the piping system can be collected and removed.
6.
To prevent contamination of instruments, all instrumentation lines shall be disconnected
during the flushing operation. These lines will be cleaned separately by blowing out with
air or flushing with water. All instrumentation lines are to be reconnected after
completion of the cleaning operation.
7.
Pressure testing will be done prior to the cleaning procedure.
Materials
1.
The following criteria will be followed for water used as a flushing agent:
•
Water containing more than 200 ppm chlorides will not be used.

2.
D.
•
Water containing more than 50 but less than 200 chlorides shall be treated with an
inhibitor of 1.5 percent soda ash and 0.5 percent sodium nitrate. The chloride content
of the soda ash and sodium nitrate will not exceed 500 ppm. These percentages are
by weight.
•
Water containing less then 50 ppm chloride does not require inhibitor treatment.
The nitric acid used shall be reagent grade material purchased specifically for this
procedure. Recycled material from a previous job is not acceptable. Acid may, however,
be reused for more than one system within the facility if appropriate acid solution quality
is maintained.
Equipment
In order to facilitate the passivation procedure, an outside 300 series stainless steel tank and
pump may be used to circulate passivation solutions. System tanks and pumps should be used,
if available.
E.
Cleaning Procedure
1.
All pipe lines will be flushed with water of specified criteria at no less than their design
flow rate. Where possible, piping systems should be sectionalized, and full system flow
rates provided through individual sections. Large diameter lines where design flow rates
are not practical shall have flow rates specified by Owner.
2.
Strainers and/or baskets should be inspected frequently during the flushing operation and
cleaned if necessary.
3.
During the flushing operation check all mechanical joints (temporary and permanent) for
any leaks that may have developed since the pressure test. Do not introduce passivation
chemicals until making sure there are no leaks.
4.
The passivation procedure will be as follows:
a.
A 10 to 15 weight percent nitric acid solution is introduced into the system and recirculated for a minimum of 30 minutes at a temperature between 115 F (46°C)
and 130 F (54°C). The solution should be circulated at a minimum linear bulk
velocity of 2 ft/s (0.6 m/s). A linear bulk velocity of 5 ft/s (1.5 m/s) is preferred.
Care should be exercised that none of the system is exposed to nitric acid of a
concentration greater than 20 weight percent or to a temperature greater than 130 F
(54°C ).

e.
To minimize staining, do not allow surfaces to dry between successive steps of the
passivation and rinsing procedure.
The rinsing procedure shall now be done with de-mineralized water. Heat water to 180 F
(82°C) and re-circulate throughout system for final rinse.
Chemical Solution and Rinse Disposal
1.
In some cases, acid may be pumped to another system for passivation without
neutralization. In these cases, the acid is rinsed from the system by water with the pH
checked to ensure adequate neutralization.
2.
The acid solution should be removed and placed in drums. If plastic lined metal drums
are used, additional caustic may be added to the drums to bring the pH above 9, to protect
the metal drums from acid attack. Arrangements for the removal and proper disposal of
waste acid drums shall be approved by Owner prior to use.
3.
Disposal of waste materials shall be in accordance with applicable local, state and federal
laws and regulations.
Degree of Cleaning
1.
Removal of all loose non-adherent material together with all adherent material that could
break away during operation of the equipment.
2.
Removal of all oil and greases.
3.

PIPING PRESSURE TESTING
3.2
Test Medium Criteria
A.
Care shall be taken to ensure the use of clean water for these tests. A suitable filter should be
provided in the filling line, should foreign matter such as sand, rust, or other particles be in
evidence in the proposed test water. The use of seawater is prohibited.
B.
All water sources used for hydrostatic testing need to be tested for MIC (Microbiologically
Influenced Corrosion Causing Bacteria) by an accredited Biological Testing Laboratory. If MIC
is detected, contact Home Office Mechanical Engineering Metallurgist for proper steps to
eliminate the bacteria prior to use. The bacteria analysis from the lab is required for proper
diagnosis.
C.
Water used for hydrostatic testing of austenitic stainless steel piping, vessels, and equipment
including those with austenitic stainless steel claddings, linings, or internals shall be tested for
chlorides and shall conform to the requirements listed below. These requirements also apply to
12 chrome claddings or linings that are welded with austenitic stainless steel weld filler, as well
as, medium and high nickel alloys and ferritic chromium stainless steel where pitting corrosion
is a risk.
1.
Water containing more than 200 ppm (Parts Per Million) chlorides shall not be used.
2.
Water containing more than 50 ppm but less than 200 ppm chlorides shall be treated with
an inhibitor of 1.5 percent soda ash and 0.5 percent sodium nitrate. The chloride content
of the soda ash and sodium nitrate shall not exceed 500 ppm. These percentages are by
weight. Systems containing water with up to 200 ppm chlorides should be flushed with
condensate or demineralized water immediately after testing.
3.
Water containing fewer than 50 ppm chloride does not require chloride inhibitor
treatment.
4.
Steam Condensate and Demineralized water that meet the requirements of 3.2B.3. is
preferred water.
5.
Piping, vessels, and equipment must be drained thoroughly after testing. Where complete
drainage is impossible, when other than demineralized water or steam condensate has
been used, the system shall be flushed free of all test water using boiler condensate or
demineralized water containing 200 ppm hydrogen peroxide with less than 1 ppm
chlorides, alcohol, petroleum distillate, or another suitable flushing solution. Hot air
drying is not acceptable in lieu of flushing, but water may be blown out of pockets using
instrument air or other dust filtered air.
6.
It should be noted that risk of pitting corrosion is considerably diminished if the time
between pressure testing and startup is as short as possible. When other than steam
condensate or demineralized water has been used and the time is anticipated to be longer
than five (5) days, flushing with condensate or demineralized water containing 200 ppm
hydrogen peroxide is recommended.

Before testing, the following procedures shall be carried out:
1.
Verify that any required heat treatment has been performed.
2.
Piping systems shall have been completely checked (punched out).
3.
Lines, vessels, and equipment shall be checked to ensure that the entire system can be
completely drained after testing.
4.
Vents or other high point connections shall be opened to eliminate air from lines that are
to receive a hydrostatic test. All air shall be vented prior to start of the pressure test.
5.
System shall be purged of air before hydrostatic test pressure is applied.
F.

All components which might be damaged by the test pressure, such as traps, instruments,
diaphragm valves, relief valves, pumps, vessels, etc, shall be blanked or removed from the
Piping systems. For welded-in control valves their internals have to be removed and stored
carefully. Valves and other in-line piping components for which the operating temperature is
below 0 degrees C shall be removed prior to hydrostatic test, unless drying out can be properly
achieved. Test pumps shall be disconnected from the test system prior to line inspection. All
piping shall be thoroughly cleaned by flushing with water, or by blowing out with air or steam,
if pneumatically tested. It shall be verified if all lines, vessels and equipment can be completely
drained after testing.

Vessels, heat exchangers and equipment, which have to be excluded from pressure testing, shall
be physically disconnected and, unless otherwise stated, flushing with water shall not be done
through these items. If there is a need to pressure test through equipment with 2 or more
pressure chambers (e.g. welded-in heat exchanger) special care is required for allowable
differential pressure between pressure chambers as stated on the Manufacturers' drawings. If
necessary, test all adjacent pressure chambers simultaneously as one system with the same
pressure or exclude all pressure chambers from the test. This applies also for de-pressurizing the
system after test completion. For these specific pressure tests a field procedure shall be prepared
and is subject to approval by Construction.
S.
In cases where a pipe line being tested extends beyond the battery limit without flanges, it shall
be tested to the first block valve or set of flanges outside the battery limit. Care shall be taken to

PIPING PRESSURE TESTING
3.12 Test Completion
A.
Pressure tests are successful if no leaks, no cracks and no deformations are detected. If leaks are
found, their location shall be marked the pressure shall be gradually released, and the piping
shall be drained or vented. All vents have to be opened and kept open in order that no vacuum is
generated. Huge amounts of water have to be drained directly to sewer inlet (e.g. by hose) in
order not to flood ground.
B.
If leaks are found on flanged, threaded, plugged or welded joints, the system pressure shall be
totally released prior to any rectification work starting appropriate repair or replacement shall be
made. The affected piping shall be re-tested at the pressures originally specified for the test.
Re-testing of minor repairs or additions may be waived, provided approval of Owner is obtained
and the welding is nondestructively examined according to Section 3.4.A.2, of this specification.
C.
After completion of testing the system shall be cleaned / flushed, all temporary blanks and

Notes:
1.
The above chart is based on ASME B16.5-2009 and ASME 16.34-2009, and provides the maximum
allowable hydrotest pressures of 1/2-inch (DN 15) through 24-inch (DN 600) flanges (shell test) and
flanged and standard class weld end valves (shell test, with valve open and seat test, with valve closed).
Test pressure for testing piping systems against closed valves, if allowed, is based on 1 times the Valve
Pressure rating, whereas the required factory seat test per ASME B16.34-2009, Paragraph 2.5.3, is based
on 110% of the Valve Pressure rating.
2.
For valves not conforming to ASME B16.34, API 600 or API 602, the Manufacturers' recommended test
pressure limits for both shell and seat shall be used.
3.
Maximum test pressures for flanges and valves over 24 inches (DN 600) and piping components not
covered by this chart shall be provided by Fluor Piping Engineering as applicable.
4.
The maximum test pressure for pneumatic testing shall not exceed 75 percent of the stated values.

PIPING PRESSURE TESTING
STATUS OF INSTRUMENTS DURING PRESSURE TEST
1.0
2.0
General
1.1
This attachment defines additional requirements for pressure testing of instrumentation.
1.2
Pressure testing of instrument process piping after the piping root valve and control pneumatic
piping are not covered by this specification.
Specific Requirements
2.1
The status of instruments during pressure testing shall conform to Table 2 of this attachment.
Instruments not covered in Table 2 shall not be subjected to pressure testing without Owner's
authorization.
2.2
When flanged instruments are removed from the test, the flange facings shall be protected over the
entire gasket seating surface with hook or plastic covers, securely attached to the instrument, to
exclude dirt and other foreign matter from the interior of the instrument and to protect the flange
facings.
2.3
When threaded instruments are removed from the test, the threaded ends shall be closed with
metal (of the same basic metallurgy as the instrument material) or plastic protectors, to exclude
dirt and other foreign matter from the interior of the instrument.
NOTE: Extreme caution should be taken in regards to Stainless Steel NPT fittings. Do not cap
ends with Stainless Steel caps or plugs, without proper lubricate, as galling will occur. Better to
use PVC threaded caps or plugs.
2.4
If spacer plates are required to be installed during testing, to replace removed orifice plates, they
shall be installed using test gaskets and test bolting.
2.5
Float type level instruments shall be excluded during hydrostatic.
2.6
The maximum allowable test pressure for displacer type level instruments shall be verified prior to
inclusion in the test. If they shall not stand the test pressure, they shall be blocked from the test
and drained.
2.7
Pressure instruments shall have their root valve closed and the drain valve shall be open during
testing.
2.8
Analyzer tubing shall be disconnected during testing.
2.9
Do not reverse flow in rotameters during testing. (This is dependent on the type, size and
placement.)

6.4
The Piping Design Supervisor will prepare a Heat Tracing Transposition.
The Heat Tracing Transposition is used to identify the scope of heat tracing including EHT already early
in the project. It indicates where the heat traced lines will run and is the start to identify the locations of
manifolds and/or tracing panels for electrical tracing. Properly maintained, it will prevent the late addition
of manifolds and additional lines with tracing fluids, such as steam and is a communication tool to the
other disciplines, Client and third parties involved in heat tracing design.
6.4.1
The Piping Design Supervisor will utilize the Flowsheet Transposition Step II to identify
all the lines that require Heat Tracing.
Refer to Practice 000.250.2010, and also to Work Instruction 000.250.1921 found in
Practice 000.250.2010.
6.4.2
6.5
The Piping Design Supervisor will make sure that the Heat Tracing Transposition clearly
indicates the different types of heat tracing and is used as the basis to locate and
determine the number of tracing manifolds.
The Piping Materials Engineer will prepare, check and issue the Piping Line Class for Tracing.
Heat Tracing is either hard-piped or tubing. A dedicated pipe class for tracing materials should be
prepared by the Piping Materials Engineer in Material Manager; tracing materials can be placed on Bills

6.10
The Piping Designer will prepare isometrics of the lead and tail lines, ensuring that leads
and tails make reference to relevant distribution and collecting manifold numbers.
The Piping Material Controller will provide the detailed quantities of piping with EHT to Electrical
Engineering whenever a Piping MTO is performed or when requested by Electrical Engineering.
Electrical Heat Tracing quantities need to be provided to Electrical Engineering in order for this discipline
to determine the required power for the EHT. A late growth of EHT can cause major change (growth) for
Electrical Engineering scope with effects on cable size, substation size, etc.
6.11
The Piping Lead Engineer will report the quantity of all tracing types in the monthly key quantity
report.
For EHT, only the quantity of piping with EHT will be reported.
Forecasting the tracing quantity should be done on basis of the Tracing Transposition and the Tracing
Specification. All different types of tracing used on the project should be tracked separately.

REQUIREMENTS
Scope & Tie-In Approval
6.1
The Piping Lead Engineer will determine the minimum engineering scope for Revamp and Tie-In
work as per the Contract, Construction and Estimate Requirements.
The Piping Lead Engineer determines which deliverables and engineering data is to be developed for
the development of the revamp work.
During FEED, Tie-In Packages are typically not needed and only the approval of the tie-in location is
needed as deliverable to the Client. For the Estimate, a routing sketch of the new line together with the
type of tie-in (cold cut, hot tap, stopple, etc.) and construction phase is required.
During Detailed Engineering, the IFC Tie-In Packages are issued. The Piping Lead Engineer determines
as per the Contract Requirements and agreement with the Site Manager what the minimum content is.
A specification for tie-in work, such as 000.250.50027, is only made when Fluor oversees third parties
that perform engineering and design for tie-in work or when required to specify requirements for
fabrication and installation contractors.
6.2
The Piping Design Supervisor will determine the physical location of the tie-ins to existing Piping
Systems.
Tie-In Locations are generally determined by Site Surveys and make use of the preliminary tie-in
locations indicated by Process on the P&IDs. Refer to Guideline 000.250.2310 for specific guidelines for

determining tie-in locations.
6.3
The Piping Lead Engineer will obtain approval from the Client for the Tie-In Locations.
To document the approval of the tie-in location, a simple package can be prepared which contains the
minimum information for the Client to approve the locations:
P&ID
Photos
Model Shot
Indication of Tie-In on Plot Plan
Tie-In List
Site Surveys
6.4
The Piping Lead Engineer will determine the minimum criteria for the Site Surveys.
As-Built verification is only to be performed when it is specifically part of Fluor’s Scope of Work.
Otherwise, existing drawings and 3D models are to be communicated to the Client as rely-upon
information.
Site survey are usually costly in terms of hours and additional costs, so clear criteria per site survey are
set to make them as efficient and short as possible.
6.5
The Piping Designer will perform the Site Surveys for the agreed scope which is to be surveyed
in the facility.
Typically, only the actual tie-in locations are surveyed in the field, preferably with the Client. Surveys of
routing of new lines through existing facilities are preferably done via the laser scans in the 3D model
and only verified at site when there is a need for that:
Unclear laser scan
Very tight lay-out
Re-use of existing facilities for which the integrity needs to be verified
P&IDs
6.6
The Piping Design Supervisor will mark up the P&IDs to indicate or update the locations of the
Tie-Ins to Piping Systems.
Refer to Work Instruction 000.250.1931
6.7
The Piping Design Supervisor will create, maintain, and issue the Demolition P&IDs based on the
P&IDs with the new tie-ins.
Demolition P&IDs indicate any demolition scope that is included in the project Scope of Work. To keep
the P&IDs readable, the indication of demolition scope is drawn on a separate set of P&IDs.
Tie-In List
6.8
The Piping Design Supervisor will create, maintain, and issue the Piping Tie-In List.

Process Data for the Tie-In List and Piping Line List is provided by the Process Engineer, refer to
Practice 000.225.2470.
There is no fixed format for the Piping Tie-In List. The Piping Data Manager (PDM) contains a standard
format which can be used in case the Contract does not have specific requirements. The tie-in list
contains, but is not limited to the following information:
Tie-In Numbers
Location (Area, CWP)
Construction Phase (Shutdown, Post-Shutdown, etc.)
Type/Method of Tie-In
Reference to Drawings and other deliverables (P&IDs, Line List)
Specific Line List Data*
*Note: Duplication of data is to be prevented wherever possible. PDM has data integration of the Piping
Line List with the Tie-In List, allowing one source of data to feed both Lists.
Laser Scanning
6.9
The Project Engineering Manager will determine if Laser Scanning is to be applied on the project.
Refer to Guideline 000.250.2310.
Laser Scanning can reduce the effort hours required for (Piping) Engineering as site surveys can be
reduced and detailed piping routing studies can be performed in the Home Office and 3D Model.
Laser Scanning is considered as an alternative method of performing site surveys, specifically in
hazardous locations and operating plants. Laser Scanning is:
Heavy Congestion Areas
Areas such as banks of exchangers, vertical or horizontal vessels, compressors, large pumps, fired
heaters or heavy congestion of piping.
High Elevations
High elevations with limited or no conventional access require special attention.
Large Diameter Piping
Large diameter piping which is very difficult to conventionally measure and survey, such as Vapor
Overhead lines from towers, heater ducts, etc.
As-Built Verification
Laser mapping can be used as a tool to verify the existing piping, equipment, etc. versus an existing
3D model or As-Built Drawings. The laser mapping model can be referenced into the 3D model and
overlaid to visually show the differences and the similarities.
Pipe Racks
Pipe Racks, certainly multi-level congested ones, are usually not a proper scope for laser scanning.
This would involve significant effort for scaffolding and platforming to be used next to a significant

number of scans to be made. Single layer, non-congested pipe racks or sleeper trackers may be
considered.
6.10
The Project Engineering Manager will develop the Technical Scope of Work for the Laser
Scanning Contract.
The Technical Scope of Work for the Laser Scanning Contract includes items as, but not limited to:
Locations, Areas, Equipment to be laser scanned
Items to be scanned
Quality Requirements for the Laser Scans
Schedule
File format of 3D Laser Scan to be supplied
Other deliverables to be supplied
Plant Monuments
6.11
The Project Contracts Manager will coordinate the contracting effort for the Laser Scanning
Contract.
3D Modeling
6.12
The Piping Lead Engineer will determine the minimum modeling scope for brownfield areas in the
3D Model.
By default, not all existing facilities are modeled in the 3D model and only the relevant existing of the
facility are included in the 3D model. When a Laser Scan is available, this can be referenced in the 3D
model to efficiently and correctly route new piping scope in the facility.
6.13
The Piping Designer will model the new Piping scope in the 3D model and only model the agreed
existing facilities.
Wall Thickness Calculations & Rerate Scope
6.14
The Piping Materials Engineer will obtain the wall thickness measurements of the tie-in locations
and verify that the wall thickness is suitable for the intended tie-in.
Wall Thickness measurements are typically performed by the Client after the tie-in locations are
determined. In case the Client does not provide these, Fluor can prepare a Contract for these services in
case this is part of the Contract Requirements or approved by the Client and thus reimbursed.
6.15
The Piping Lead Engineer will coordinate the rerating scope for Piping in case this is included in
the Scope of Work for Fluor as per Work Instruction 000.250.1932.
Tie-In Packages
6.16
The Piping Lead Engineer will determine the content of the IFC Tie-In Packages based on the
Contract Requirements and align it with Construction & Fabrication.

PIPING DESIGN - REVAMP, BROWNFIELD AND TIE-INS
The contents of the IFC Tie-In Packages vary from project to project and may be directed through the
Contract Requirements (e.g., Client specifications). The Piping Lead Engineer determines the minimum
content required as per the Contract Requirements and confirms the minimum requirements with the
Site Manager. Certainly, when Laser Scanning is used, the need for all “paper” deliverables can be
minimized, as the 3D Review Model can be used at site as well.
Typical content of an IFC Tie-In Package is:
P&ID
Demolition P&ID
Marked-up existing isometric
New isometric of new line
Tie-In Location Plan (plot plan background)
Piping Line List
Piping Tie-In List
Photos
Reference to Welding, Testing, Painting, and Isolation Requirements
6.17
The Piping Design Supervisor will prepare, check, and issue the Piping Tie-In Packages per
Construction Phase as per Work Instruction 000.250.1931.
Scope of different phases is to be specifically segregated, as the Construction Work Packages (CWPs)
are different, might involve different contractors and materials have a different Required At Site (RAS)
date. Typically, most tie-in work is performed outside of the plant shutdowns to the maximum extent, as
plant shutdowns are very costly for the Client.
The typical phases when (part of) tie-ins are installed are:
Pre-Shutdown
Shutdown
Post-Shutdown
Anytime


TESTING

FORM INSTRUCTIONS

ATTACHMENTS
APPLICATION
This document is to be used as a guideline for making piping tie-ins, including
selection, location, and design of tie-in connections to existing piping and
equipment. Also to be used as a guide for completing Attachment 02 and
Attachment 03.
RESPONSIBILITY

The Lead Piping Engineering will be responsible for the physical location,
design, initiation of material procurement for the tie-in, and completing the tiein forms.

The Lead Process Engineer will establish tie-in process requirements.

Construction will establish blinding, purging, safety procedures, and will
perform NDE (Nondestructive Examination) on the proposed locations.

The client will approve tie-ins, content, and locations.
DEFINITIONS
Tie-In: A new piping connection to any existing pipeline or piece of equipment
which is made in place.
Pressure Tap (hot tap): A tie-in made by drilling or cutting a line or vessel, which
is either under pressure or vacuum without losing product or interruption systems
operations.
Stopple: A device used to isolate a section of pipe for repair or revision without
depressuring or clearing the entire line. Requires a custom design fitting to be
installed, and a hot tap to be performed first.
TIE-IN
GUIDELINES
Review Requirements
 Use as-built P&IDs (Piping and Instrumentation Diagrams).

TIE-IN PRACTICES – GENERAL GUIDELINES


Check for special process requirements such as the following:
- Do not pocket/Free draining/Slope lines
- Vibrating service
- Allowable pressure drop
- Two-phase flow.
With Client Operations Representative, determine hot-tap or cold-cut.

Prepare tie-in list. See Attachment 02 and 03.
Locate Tie-In in the Field
The majority of tie-ins to existing facilities will be accomplished during a Plant
shutdown.
Those piping systems remaining live during a Plant shutdown and requiring tie-ins
will be identified as such in the preliminary flowsheet markups. As illustrated by the
following items, special care and attention will be given during the design phase,
which will be effective in minimizing system shutdown requirements:

Tie-in points will be tagged with a weatherproof tag indicating the job number
and tie-in number, and will be fixed to the tie-in location by means of a semipermanent but removable device such as a wire. The tie-in point will be painted
on the pipe or valved tie-in point with a color of paint which is acceptable to the
Plant Engineer.

It is good practice to photograph each tie-in after tagging in the field, for
recording purposes.

Tie-ins will be as shown on applicable P&IDs.

Use existing connections when possible.
- Valve with no connection.
- Blind flange; tap off with sealed plugs for small bore.
- Replace existing flanged spools with new spools incorporating a connection
point.
Choose locations which can be blocked by existing valves.


Review and obtain approval of tie-in locations with Process, Operations, and
Maintenance.

Determine testing requirements.

Use Attachment 02 FSR (Field Service Request) Tie-In List Instructions and
Sample Forms, for manual measurements and survey data.
- Determine existing reference coordinates and elevations by survey, and
paint the information on the reference item in the field; for example, pipe
support column coordinates and top of steel elevations.
- Measure from marked columns and steel elevations.
- Take pipe measurements from welds rather than from hard-to-find
centerline of elbows or Tees.
- On critical tie-ins, have centerline elevation and 1 set of coordinates
surveyed to complement manual field measurements.
- Perform UT on existing line. (Does it meet code?)
- Determine type of PMI (Positive Material Identification) on the existing
line.
- Determine type of existing insulation or tracing.

TIE-IN PRACTICES – GENERAL GUIDELINES

When the Fluor Piping Design team is close to completing their work, the Fluor
Piping and Process Engineers will travel to the plant site and together will check
the Plant Design team work from a Process and constructability standpoint.

When piping tie-ins are checked by Fluor Piping and Process Engineers, they
will be reviewed with the plant's Project Engineer for approval.

After preliminary approval by the plant's Project Engineer, Fluor Piping will
formally draw up the Piping tie-in isometrics and Piping tie-in key plans, and
develop the Piping tie-in list which will be issued formally for approval.
Prepare Demolition Isometric
 Demolition can be shown on existing isometrics or be part of the new tie-in
isometric.

Demolition isometrics show Construction exactly where the existing line has to
be cut to install the new tie-in.

Piping and process should review P&ID and isometric for alignment.
Design Routing of Line from Tie-In to Destination

Field check for clearances, by Piping Lead or Designee.

Try to maximize the use of existing steel. (Pass the additional loads to CSA on
existing steel, especially on large bore lines.)

Do not block future expansions.

Use 3D Laser Scanned image as reference for design, where applicable.
Review Isometrics
 Verify constructability (such as crane access and welder access).

Verify clearances for hot-tap machine (if required).

Verify clearances for bolt tensioning, where applicable.

Verify sketch's level of detail; does it show existing anchors, guides, and
supports (for stress review)?

Verify that thermal expansion has been accounted for when taking existing line
field measurements.

Consider flanged spools if hot work is not permitted, or limited in accordance
with construction strategy.

Verify that existing isolation valves are shown.

Verify new loads have been passed, and agreed to by CSA, if existing structure
has been used.

Considered the actual available shutdown time and the time required to cool the
line (if it is hot), then cut it, pre-heat for weld, welding time, post-weld heat


Nozzle reinforcement material will be of the same nominal chemical
composition and physical characteristics as the branch connection and the
equipment being tapped.
Pressure Taps
 Pressure taps must be approved by Owner's Engineer.





Pressure taps may be used for the following:
- To provide a connection into Piping or Process equipment without
disrupting normal process operations.
- To provide a connection into Process equipment that has been depressured
but which is impractical to prepare for "hot work." An example would be
connections into long underground pipelines.
- To provide a connection into a pipeline for inserting a plugging or stoppling
device to isolate equipment or a section of pipe.
Pressure tapping of lines or vessels containing the following is not permitted
unless written approval is obtained from the client, and client approved
procedures are followed:
- Compressed air
- Caustic soda
- Oxygen
- Unsaturated hydrocarbons
- Decomposable
Pressure taps will not be used unless it is impractical to employ conventional
methods.
Each tap will be evaluated on its own merits considering operating conditions,
material contents, and location. The following requirements will be met:
- Pressure taps will not be made in equipment while it is operating at a
temperature below the metal transition temperatures.
- Special preheat, welding, and post heat procedures may be required for
pressure taps that will be made at low temperatures (below 40 degrees F; 4
degrees C).
- Pressure taps will not be specified for equipment handling amine (MEA and
DEA) or caustic, if operating conditions would require stress relief.
- Pressure taps will not be specified for equipment or lines containing
flammables below atmospheric pressure, or containing a mixture within the
flammable range and operating at any pressure.
- Pressure taps will be avoided or special precautions specified when air
hardening alloys are involved.
- Pressure tapping of equipment containing hydrogen is permissible, provided
the equipment has not operated above the Nelson curve limits.
- When equipment containing hydrogen sulfide or other toxic materials is to
be pressure tapped, special safety precautions for these materials will be
specified.
- If equipment handling ethylene, butadiene, or acetylene is to be pressure
tapped, special precautions must be taken to maintain circulation and
prevent overheating and thermal decomposition (with possible explosion) of
the contents.
Do not pressure tap pressurized piping or pressure vessels at locations where
fluid flow does not exist.

TIE-IN PRACTICES – GENERAL GUIDELINES

Pressure tapping of storage tanks will not be specified, except at locations on the
shell where the liquid level can be maintained at least 3 feet (0.9 m) above the
highest point of welding during welding operations.

Do not pressure tap equipment upstream of rotating machinery, unless facilities
exist (such as strainers) that will prevent cuttings and droppings from reaching
the machinery.

Bolt-on connections will be used for pressure tapping cast iron equipment.

Pressure tapping of reinforced concrete pressure piping (or other internally lined
equipment) is allowed; however, special tapping materials, equipment, and
techniques are required.

Design of pressure tap connections will be in accordance with the applicable
Codes and Standards.

Locate pressure tap connections according to the following:
- Allow sufficient clearance to install connections and operate the tapping or
plugging equipment.
- Whenever possible, locate connections so welding is performed at least 2
feet (0.6 m) from flanges, threaded connections, and riveted joints. This
should prevent leaks from developing in those joints.
- Locate connections so that no welding is required within 2 inches (50 mm)
of an existing weld.
The nozzle length must be determined for the particular tapping machine that
will be used in order to ensure a complete cut through the equipment wall. In
addition, for flanged nozzles, the length should be adequate to permit removal of
flange bolts. When practicable, the face-to-center line dimension of flanged
nozzles for perpendicular connections to pipeline should be the same as the
corresponding dimensions for a welding tee, and welding neck flange of the
same size and rating as the tapped line.


Connections will be the reinforced type using one of the following:
- Pressure tap connections for size-to-size connections will be a full
encirclement saddle (3-inch minimum (75 mm) width and a minimum
thickness of either 1/4 of an inch (6 mm) or the header wall thickness,
whichever is greater).
- Pressure tap connections for other than size-to-size will be one of the
following:
a) Integrally reinforced welding outlet fitting (fully welded).
b) Reinforcing pad (3-inch (75 mm) minimum width and a minimum
thickness of either 1/4 of an inch (6 mm) or the header wall thickness,
whichever is greater).
c) Full encirclement, weld-on saddles (3-inch (75 mm) minimum width
and a minimum thickness of either 1/4 of an inch (6 mm) or the header
wall thickness, whichever is greater).
d) Full encirclement, bolt-on saddles where attachment by welding is not
permitted.
- Pressure tapping connections for cast iron pipelines will be full
encirclement, bolt-on saddle.
- Stoppling connections will be full encirclement type, fitting equal to T. D.
Williamson's stopple fitting.

TIE-IN PRACTICES – GENERAL GUIDELINES

Connections will be designed to prevent buckling of the surface being tapped,
due to application of test pressure to the inside of the branch connection. An
acceptable method for calculating the buckling pressures in externally loaded
cylinders is given in R. J. Roark's Formulas For Stress And Strain, Fourth
Edition, Page 54, Item S(34).

The minimum pressure tapping nozzle and valve size specified will be 1 inch
NPS.

Heating or purging of the tapping or stoppling connection will be specified, if
the equipment contents will be solid at ambient temperatures.
NOTE: All Pressure Taps should be reviewed with HSE.
Bolt-On Connections
 When welding or other hot work is not allowed, pressure taps using bolt-on
connections will be considered.

When bolt-on saddles are used to pressure tap equipment within limits or in fire
hazardous areas, a fireproof gasket will be specified.
Valves
 Valves must have clear, full round openings at least 1/8 of an inch (3 mm)
greater in diameter than the specified drill or cutter OD. Valves will be
inspected for sufficient clearance of cutter prior to tapping.


Regular-port (not tilted-port or venturi-port) gate valve with the same NPS and
rating as the branch connection will be specified, except as follows:
- Ball valves may be used, if port opening and material specifications are
adequate.
- Corporate plug cocks (3/4 of an inch NPS) may be used in water service, if
the line being tapped is cast iron or steel, Schedule 40, and is 4 inch NPS or
larger.
- If maximum drill diameter is required for valves size 2-inch NPS and
smaller, full-port valves equal to Smith Valve No. 88 (threaded or
socketweld).
- Flanged full-port valves will be either API 600 pattern (available in 1- 1/2
inch and 2-inch sizes) or forged body (available in any size as a special
order); check availability with the Material Engineer.
For valve sizes 2 inch NPS and smaller (other than full-port type), it may be
necessary to use a drill diameter one size smaller than that specified in order to
clear the valve seat rings. This decision must be made in the field after the valve
has been selected, since inside dimensions of the smaller valves vary widely
with manufacturer and style.
Testing
 The hot tapping or stoppling connections, reinforcing pad, valve, machine, and
joints will be pressure tested prior to tapping the line.

Hydrostatic test shall be specified for equipment operating between 40 and 200
degrees F (4 and 95 degrees C), unless other special conditions require a

different test medium. Air, nitrogen, or another inert gas shall be specified for
other temperatures.
Test pressure for the valve, nozzles, and reinforcing pad (if required) will be as
follows:
-
For tanks, test pressure will be 40 psi (275 kPa).
For piping and pressure vessels, test pressure will be calculated in
accordance with the applicable code and will be based on the most severe
combination of design pressure and temperature (not the operating
conditions), since operating conditions may change from time to time.

a.
Ball valves may be used if port opening and material specifications are
adequate.
b.
Corporation plug cocks (3/4 of an inch NPS) may be used in water service if the
line being tapped is cast iron or steel. Schedule 40, and 4-inch NPS or larger.
c.
If maximum drill diameter is required for valves sizes 2-inch NPS and smaller,
full port valves equal to Crane Company's No. 3607XU (threaded) or No.
3615XU (flanged) shall be specified.
For valve sizes 2-inch NPS and smaller (other than full port type), it may be
necessary to use a drill diameter 1 size smaller than that specified in order to clear
the valve seat rings. This decision must be made in the field after the valve has been
selected since inside dimensions of the smaller valves vary widely with manufacturer
and style.

2.3
Regular port (not tilted port or venturi port) gate valve with the same NPS (Nominal
Pipe Size) and rating as the branch connection shall be specified, except as follows:
Hot Tapping
1.
Some pipe systems may be unsuitable for hot tapping because the metallurgy or
thickness of metal requires stress relieving, which normally cannot be done while the
system is in service. Special treatment is required for high tensile strength alloy
steels, and special welding electrodes must be used. Hot tap fitting and weld rod
metallurgy must be compatible with piping to be welded.
2.
The base metal thickness must provide support for the new connection and the hot
tap machine or be properly reinforced to provide such support. Generally, a
minimum base metal thickness of 3/16 of an inch is recommended for hot tapping.
A minimum base metal thinner other than 3/16 of an inch shall not be hot tapped
without written authorization from Fluor Daniel and Client.
3.
The base metal must be free of lamination, hydrogen attack, or stress corrosion
cracking. There must be no other imperfections that would prevent a solid weld
from being made.
4.
Stress relieving of the welded area must not be required.
Hot Tap Machine Criteria
A.
The hot tap machine shall be of the proper size and rating to accommodate the required
pipe branch connection.
B.
Hot tapping machines have a maximum working pressure and temperature rating which
shall not be exceeded. The machine may be powered by hand, hydraulic fluids, or
pneumatic drives. Electric motor drives are prohibited.

materials, and location. The following requirements shall be met:
a.
Hot taps shall not be made in equipment while it is operating at temperatures below the metal transition
temperatures.
b.
For hot taps that will be made at low temperatures (below 40 degrees F), special preheat, welding, and postheat procedures may be required.
c.
Hot taps shall not be specified for equipment handling amine (MEA and DEA) or caustic, if operating
conditions would require stress relief.

b.
Locate connections so that welding is performed at least 2 feet from flanges, threaded connections, and
riveted joints, whenever possible. This should prevent leaks from developing in those joints.
c.
Locate connections so that no welding is required within 2 inches of an existing weld.
The nozzle length must be determined for the particular tapping machine that will be used so as to ensure a complete
cut through the equipment wall. In addition, for flanged nozzles, the length should be adequate to permit removal of
flange bolts. When practicable, the face-to-center line dimension of flanged nozzles for perpendicular connections
to pipelines should be the same as the corresponding dimensions for a welding tee and welding neck flange of the
same size and rating as the tapped line.
Connections shall be the reinforced type using one of the following:
a.
Hot tap connections for size-to-size connections shall be a full encirclement saddle (a minimum width of 3
inches and 1/4 of an inch minimum thickness).
b.
Hot tap connections for other than size-to-size shall be 1 of the following:
1.
Integrally reinforced welding outlet fitting (fully welded).
2.
Reinforcing pad (a minimum width of 3 inches and 1/4 of an inch minimum thickness).

02 TIE-IN LINE NUMBERING EXAMPLES
This is an example of a standard approach to numbering Tie-In lines. Client specifications and practices will be properly reviewed for
applicability when developing project-specific Line Numbering requirements.
The following are two different situations for Tie-in lines:
a.
Existing – New – Existing
When lines are rerouted and a new line section ties into the existing line, the Line Number will stay the same with only a suffix
e.g., ‘A’ will be added to the Line Number. By adding this ‘A’ to the Line Number, this part will be recognized as a “new” line for the
project.
Example: Existing line number is P-12001-10”-F01A
New line number is P-12001A-10”-F01A3
b.
Existing – New
When a line is rerouted in a unit with a new destination in that unit, a new Line Number will be assigned.
Example: Existing Line Number is P-12001-10”-F01A
New Line Number is P-12031-10”-F01A3

03 TYPICAL PIPING LINE LIST STRUCTURE AND ADDITIONAL FIELDS
1.0
TYPICAL LINE LIST STRUCTURE
The Piping Line List can be a manual form, a computer generated report or database. Whatever form it will take, the elements of
the Piping Line List will include the following (the field size is normal, but will need adjustment to meet project requirements):
2.0
a.
Revision (2-place alpha-numeric field) to indicate a revised line.
b.
WBS or Area/Unit information (3-digit numeric field).
c.
Line Number (Sequence Number) (3 to 5-digit field), unique within an Area or Unit
d.
Line Class (4-place alpha-numeric field).
e.
Line Size NPS or DN (4-place numeric field with fraction capabilities for NPS). Trim Line Numbers will not require size
entry.
f.
WBS or Area/Unit information (3-digit numeric field).
g.
Line Number Fluid Service code.
h.
Steam Out requirements - Y/N (Yes / No). Process will provide design temperature and pressure during steam out.
i.
Service – use consistent designations as defined on the Project Service Index.
j.
Vapor / Liquid / Solids (3-digit field to allow for multi-phase flow)
k.
From (the origin of the line) and To (the terminus of the line). Use equipment numbers where possible and abbreviate
consistently.
l.
Design and operating pressure and temperature (4 fields with 4 numeric places each). Units will be psig and °F (imperial)
or MPag and °C (metric).
m.
Type of insulation and heat tracing (symbols as defined on flow diagram legend, in Client specifications, or Fluor
Specifications - such as 000.285.85110 Specification - Hot Insulation or Cold Insulation specification if available and
applicable).
n.
Indication of stress check required - Y/N (Yes / No) as indicated by Piping Stress Engineer per 000.250.50200 Specification
for Piping Flexibility.
o.
PWHT (Postweld Heat Treatment) Requirements - Y/N (Yes / No). This is as required by MSD, P&ID, or ASME Code
requirement.
p.
Field test type and pressure (psig): H for Hydrostatic Leak Test (water), P for pneumatic Leak Test (air), I for Initial
Service Leak Test (Commodity test), and NA for identification for vent and drain lines unblocked and opened to the
atmosphere. These lines will not require pressure testing.
q.
Remarks, if any, in this field will indicate any special or alternate (upset) design conditions or special requirements.
ADDITIONAL LINE LIST FIELDS TO CONSIDER
PME will consider the impact of any changes to the Line List in revising software and additional time to construct and maintain
the Line List.
a.
Fluid Category, Hazard or Toxic indication.
