Must the pressure vessel testing bolts be official ones?
Thread Content
Dear sea friends, are formal pressure testing bolts required for pressure vessels?
For pressure vessel pressure testing, the bolts need only meet the specifications specified in the drawings.
It is best to use the original accessories, as the bolts are also part of the strength test
There are no requirements in national standards; it is only for bolts with high-pressure, non-standard designs that it is generally necessary to use standard bolts for pressure testing, right?
Use the one built into the container, with a separate official fitting for the pipe outlet.
In principle, the designed official gaskets and fasteners must be used during pressure testing in order to reflect the actual effects of such testing.
Compliant bolts or studs should be used, with emphasis on stress resistance
