Pressure vessel flange bolts
Thread Content
Can pressure vessel flanges be secured with bolts, and why not?
It depends on whether it is a device flange (for cylinders or end caps) or a pipe flange. Device flanges use studs, while pipe flanges can use bolts at pressures up to 1.6 MPa; for higher pressures, studs are used instead. Bolts cannot withstand stress as well as studs, and their ends tend to come loose easily. .
Aren’t bolts used to fasten flanges?
Does the term \"bolt\" mentioned by the original poster refer specifically to a single-headed bolt? Pressure vessels generally use double-headed bolts.
Refer to the standards NB/T47020-47027-2012
It can be used; refer to the pressure vessel flange standard HG20592-2009, which contains specific requirements regarding the bolts or studs used with flanges
There are specific standards for pressure vessels; please refer to NB/T47020–NB/T47027-2012. For pipe flanges, refer to HG/T20592-2009. These two sets of standards are different from each other
There are specific regulations in the standards; follow them

The fasteners specified for container flanges don’t seem to include bolts, so I think using studs is safer and more reliable.
