This is for station piping pertaining pipeline , construction code is B31.8.
-- Our client Spec required -45 degree impact at LTCS material , where all material belongs to P1G1. And remaining material/Class required impact @-20 degree. For minimize PQR I have proposed P1G1#P1G3 combination. Impact of Weld and G1 HAZ will carry out in -45 degree and G3 HAZ will be carried out in -20 Degree .
Is it Okay in Code and technical point of view , right ?
