How should the coefficient for circumferential weld joints in pressure pipelines be determined?
Thread Content
Where is this information specified in the standards? Could it be that the coefficient for circumferential weld joints is set at 1.0?
The grade is related to the pipe grade; some are 0.8, some are 1.0, and some are even lower.
Could you tell me which regulations contain provisions on this matter?
:Lol, as long as the longitudinal seam calculation is satisfactory, that’s fine. .
I installed the software for obtaining values related to pressure vessels, but I’m not sure why this coefficient needs to be specified. It seems like it’s not necessary to include this in the pipe characteristics table, right?
The grade is related to the pipe grade; some are 0.8, some are 1.0, and some are even lower. Refer to what was said above; I’m not really familiar with the specifics either, so it’s recommended to check the relevant manuals
The pipe characteristic table in HG/T 20519 does not specify the welding joint coefficient
It is listed in Table A3 of GB/T 20801.2, but only the longitudinal seam coefficient is mentioned, while the circumferential seam coefficient is not addressed； I also want to ask: Is the joint coefficient of the pipe-to-flange girth weld affected by the gasket? . .
