Hi All

We need to analyse an underground piping using ASME B31.3
In ASME B31.8 we define restrained & unrestrained. The allwobles considered for underground piping in ASME B31.8 are also high. But I could not find any specific requirements or procedure for analysis of underground piping using ASME B31.3

If anyone has got idea related to this then please guide us. Kindly highlight considerations like restrained,unrestrained & allowables to be used.

Thanks
