Notas
Carga en libras sobre los espárragos cuando el torq
ue arriba
señalado sea aplicado
La cuerda del perno la tuerca y la superficie deben
estar lubricados
antes de apriete
Es muy recomendado que el equipo de apriete hidrául ico sea usado
en pernos de 1 1/8” hacia arriba
Controlar el apriete del perno es muy recomendado p ara minimizar
el riesgo de fugas en el ensamblado
En el ensamblado lo que fuga es la brida y no el em
paque.
