Verification of pressure vessel plugs
Thread Content
Recently, there was an ASME vessel with a drain plug on its flat bottom cover. The AI requested that a verification calculation be carried out for this plug. Dear experts, how should this plug be verified through calculation?
Add the dimensions of the plug, with the thread standard being ANSI B1.20.3
The openings have been calculated; standard plugs can be used for them
This is a small opening; standard reinforcement can exempt it from calculation. The plug is not the standard type, and it will not be replaced with a standard one at the moment. Is there any specification that provides a calculation method for this?
The openings have been calculated; the plugs are not of standard type, so they need to be calculated as well. At present, it’s not possible to replace them with standard ones.
May I ask how to verify a plug that is not standard? Are there any formulas in relevant standards for this purpose? Thank you.
What needs to be verified for the plug? ASME specifies requirements regarding the minimum number of connection threads; nothing else is clear.
According to AI, it is necessary to verify the strength under pressure, as well as leakage...
I also have a question: in which chapter of ASME are the requirements regarding the minimum number of connecting threads specified? Thank you.
It’s difficult to calculate after learning it; it’s best to choose according to the standards.
