Selection of manholes for high temperatures (600 degrees)
Thread Content
The container design I am working on has a design pressure of 1.0 MPa and a design temperature of 600 degrees; it is made of 316 material. However, the temperature range specified in HG/T 21594–21604-2014 is up to only 300 degrees. What should I do? Everyone, please help
In such cases, we usually choose a pressure rating for use; of course, the flanges are also made of pure stainless steel, and it’s not a manhole with a lining.

One has to design everything by oneself – the cylinder sections, flanges, flange covers, bolts, gaskets, hooks, rods, eyelets, and so on; one has to calculate and draw them all on their own
Design it yourself; once it passes the verification, it’s fine.
Designed by itself; the flanges and flange covers adopt a surfacing welding structure
Designed independently, featuring a fully stainless steel structure.
Self-designed solutions that go beyond the standard range are acceptable
