Pressure vessel with jacket?
Thread Content
As the title suggests, it is a medium-pressure vessel at 4.0 MPa with a jacket; steam at approximately 360°C is present inside the jacket. How should the design pressure of the medium inside the jacket be determined? Is it based on the pressure of the inner cylinder?
It is important to distinguish between design pressure and calculated pressure!
Steam design 360℃? Superheated steam? You might as well use heat transfer oil.
Later, the client switched to electric heating.
The jacket is originally a separate chamber; therefore, the design pressure should not be determined based on the conditions inside the container, but rather according to the operating conditions of the jacket itself
The pressure in the inner cylinder has no effect on the jacket; so what is the relationship between the design pressure of the jacket and that of the inner cylinder?

Designed separately. The inner cylinder is the inner cylinder, and the jacket is the jacket. GB150 specifies clearly that the design pressures for each pressure chamber should be determined separately.
