Does anyone have any experience using an inflatable seal (i.e., a Pawling or similar inflatable gasket) as a pressure vessel closure? This would be the only component sealing the main vessel closure/cover and I'm concerned that it will not meet ASME B&PV UG-35.2 criteria. The vessel is designed...
We are a fabricator of stainless steel pressure vessels and are going through the process of getting our license to the subject specification for export to China (by our customer). The material requirements jump from carbon and low alloy steel material to aluminum and non-ferrous materials...
I have an ASME Div. 1 Sec. VIII SA240-316L SST pressure vessel that has internal coils at -238F. The vessel itself is normally operated at atmospheric pressure or under vacuum at -103F, but is also periodically steam sterilized at 30 psig and 275F. I usually rate these at 30 psig/FV at 275F with...
Will passivation or pickling remove ferrite from the surface layer of 316L stainless steel? I'm not talking about free iron contamination, but the actual ferrite as part of the grain structure of the metal.
I have a customer that I'm building a vessel for and the product is sensitive to ferrite...
This may sound obvious, but UG-47 and UW-19 only apply to pressure between the two plates being braced and stayed, correct? One of my collegues is trying to apply these rules in designing a jacketed rectangular vessel with flat walls as if the pressure (P) from UG-47 is inside the rectangular...
Does anyone know whether a sanitary ferrule to ASME BPE-2002, DT-2 is acceptable for use on a pressure vessel to ASME B&PV code section VIII? Table DT-2 in BPE-2002 gives limited pressure/temperature ratings for the fittings but does not specifically cite section VIII acceptability. Also, ASME...
