Dear Mezrar,

It depends if Client has any Pigging Specification. In one of my project we were going to design as per B31.3 due to piping connected was also B31.3. but later we found that the Client Spec was saying about ASME Sec VIII Div. 2 hence we had to change the design code.

Also the pig receiver design code has to be designed as per the connecting piping code which is by Piping.
