Can flanges in accordance with ASME standards be used directly on pressure vessel equipment?
Thread Content
I would like to ask the experts: Can flanges in accordance with the ASME standard be used directly on pressure vessel equipment?
It depends on which standards are used as the design criteria for this pressure vessel; if the ASME standards are applied in the design, then it can certainly be used
Equipment designed in accordance with GB150 and subject to tolerance-based inspection
According to Article 3.2.5 of the \"TSG 21-2016 Safety Technical Inspection Regulations for Fixed Pressure Vessels\", reference should be made to the \"HG∕T 20592~20635-2009 Steel Pipe Flanges, Gaskets, and Fasteners\" standard, which includes PN and class series
If the flange is designed in accordance with ASME standards, then a series of procedures must be followed based on the requirements for foreign materials outlined in the Code for Pressure Vessels, including inspections, re-inspections, and the preparation of weld evaluations.
Using it within the country is another matter.
HG20615 is the same as ASME
This situation is not uncommon; considering that the container needs to have piping flanges in place, I believe that the ASME-standard flanges on the container do not need to follow the same material specifications as those specified for external components.
