plugs, caps, flanges for hydrostatic pressure test
(OP)
is there recomendation for the material type for plugs to pressure testing of the welded pipe line made by super duplex material and carbon steel with inconel clad. a specialy with thinking om contamination aspect. Recomendations in standars such as ASTM. if yes where can if find this in standards?





RE: plugs, caps, flanges for hydrostatic pressure test
Selection of a specific material type from one of the ASME B16.XX specifications or similar standards is based on engineering judgment. If you are attaching plugs or blanks by welding consideration should be given to provide enough base material to allow complete removal of the plug without affecting the pressure part base material.

I added the comment because when you select the material using a standard like ASME B16.5 or other, you need to know both pressure and temperature. Typically, I use the minimum temperature for the hydrostatic test. That is it.
