Application Comments Max Detensioning Pressure refers to the maximum capacity of the tensioning tool and should not be considered to be the safe max load capacity of the flange 100% Tensioning is the recommended mode of bolt tensioning, wherever possible use 100% Bolt to tool ratio © 2020 Tentec Limited Tentec Limited do not accept any liability for errors within or caused by the use of this software. - All Rights Reserved
