Pressure vessel manhole or hand hole for help
Thread Content
What is the professional name of the manhole or hand hole in the circle, how much pressure can it withstand, and what are the design standards?
2.0mpA is no problem, it depends on the structural size!
This is the boiler manhole, you can check the standards. The key point is that there is no problem with the opening reinforcement and the sealing plate. The seal is a self-reinforcing seal and there is no problem.
