Dear All
My case is:-
code of construction- ASME B31.3
LPG/LNG pipeline
For Pig signaller, we have to weld a barred tee in the pup piece attached with valve.
pup piece material- API 5L X60 PSL2
barred tee- ASTM A860 WPHY 60
length of pup piece is 125 mm. Kindly find the attached drawing for welding connection.
Acc. to Australian std distance between welds should be 6 times of thickness, in this case we r not able to weld.
PLS confirm looking at the drawing, can the welding be performed?
