Selection of materials for safety valves in waste heat boilers
Thread Content
I don’t know how to choose; are there any minimum requirements? Process conditions: saturated steam at 250 degrees, i.e., medium-pressure steam at approximately 5 MPa (A). Only the calculation scheme for the safety valve was found; what’s missing is the selection of materials, and it can’t be located.
Depending on the temperature and pressure conditions, either cast iron or carbon steel valve bodies are used, with bronze or stainless steel internals
