Minimum size of ASME code vessel
Minimum size of ASME code vessel
(OP)
Dear Folks;
Is there a minimum size or volume below which vessels do not have to be ASME code certified.
This question arises from dust collector air headers. Which, I have been told do not need pressure vessel certification below a certain volume.

RE: Minimum size of ASME code vessel
...i) vessels having an inside diameter, width, height or cross section diagonal not exceeding 6" with no limitation on length

For example, pipeline pig launchers/receivers and compressor pulsation bottles can be fabricated piping assemblies.

The ASME B31.3 Process Piping Code also includes provision for pressure less than 15 psig and temperature less than 366 deg F for non-toxic non-flammable fluid services being excluded from the scope of the B31.3 Code. I think the ASME vessel Codes have similar 15 psig threshold for application. Your dust collection air headers may be outside of ASME scope.

The air pressure in this header is 80 psig
Also 1969grad,
the fabricated piping assemblies idea sounds good
thanks also metengr I will check out the PV code section you mentioned.
