Is it necessary to verify the strength of low-pressure vessels under purging conditions?
Thread Content
It is a low-pressure device with a design pressure of 0.5 MPa; under purging conditions, the steam temperature is 290°C and the pressure is 1.0 MPa. Is it necessary to consider the strength of the device under these conditions?
What are the design temperature and pressure? It’s better to conduct a verification, even if it’s only for the shell
How can 1.0 MPa result in 290°C? Strength verification is required!
High-temperature steam purging, temperature 290℃
It’s necessary; calculate it to be sure, and with a basis for it, the using unit can also carry out purging with confidence!
OK. . . . Thank you~~~~~~~~~~~~~
Personally, I think 16MnDR should be used as the main material, or 09MnNiDR, which offers higher safety performance. Stella Special Steel Services – hope this is helpful to you.
