Re: [MW:16834] ASME code construction limits

Dear sir if the vessel construction is  as per ASME Sec.VIII , then the internals also  will governed by same code.

Guys,

Pls put your comments for the below query

If a vessel is constructed as per ASME Sec.VIII then what will be the code of construction for
the internal pipes being used for that vessels?Will the pipes falls under Sec.VIII or B31.3?

Also is it required to do a pwht for that pipes if pwht is not a service requirement for vessel
and if the pipe wall thickness SA 333 Gr.6 exceeds 19mm ?

Is it allowed to use the wps in accordance with ASME SEC .IX and ASME Sec.VIII for piping of that
internal pipes and also for other piping jobs as per ASME B31.3 works.
