Thickness of Pipline (ASME B 31.4/31.8) v/s Thickness of Piping (ASME B 31.3)

[cjabhijit]

Dear Experts,

Need your quick help on the subject line.

In general What I think is ASME B 31.3 is far more conservative when calulating Thickness of Pipe when compared to Pipeline Code ASME B 31.4/31.8.

The reason being Safety in Process plant environment is considerably critical when compared to the Popeline travel in differenct Geogrhies.

Pls share your knowledge regarding the same.



Thanks & Regards,
Abhijit

Could depend on what loads are present on the pipe line? There can be other loads too. Waves on platform risers? Span distances! Perhaps you are only referring to the thickness required for pressure. If only it were that simple.

B31.8 has 0.4 and 0.5 design factors for city installation.
