Problems with welding the flat cover to the cylinder of pressure vessels
Thread Content
As shown in the figure, this flat cover is welded to the cylinder; the design pressure is 0.35 MPa, the design temperature is 150°C, and the medium is water vapor
There is no schematic diagram of this structure in GB 150.3 5.9; how should the welding structure of this flat cover with the cylinder be calculated?
If it really doesn’t work, you can change the structure
GB150.3 Table 5-9, Item 4
GB150.3 Table 5-9, Item 4
It’s just that the workers who are responsible for modifying the structure find it troublesome to do so; the original simple structure is still preferred. I’m just wondering if this type of structure is reasonable – after all, there’s no explicit prohibition in the standards
The workers in charge of modifying the structure think it’s too troublesome to do so; they prefer to stick with the original simple structure. I just want to ask whether this kind of structure is reasonable – after all, there are no explicit regulations prohibiting it
It is recommended to use a standard structure...
Refer to HG20583
The design pressure is 0.35 MPa and the design temperature is 150°C. Why is a flat cover used?
