Hello folks,
In my current Pipeline project, Construction code is AS 2885.
Pig Launcher designed as per AS 2885 welded to ASME sec Viii div 1 designed end closure, Which code to be followed for PWHT. ASME sec Viii div 1 states PWHT above 38mm thickness and AS2885 specify above 32mm thickess. Never encountered such problems, should you need more info, feel free to ask me.
Your inputs are most awaited and appreciated.
