I’m not an expert in pipeline design; could everyone please check whether it’s correct to use a stainless steel pipe swivel flange paired with a carbon steel flange? Please state the basis for the standards or norms
No problem; the flanging ring is made of stainless steel while the loop is made of carbon steel – this is the standard practice, as specified in HG20592 for loop flanges.
No problem; in the example marked on page 90 of HG/T20592, the weld ring material is 316L, and the flange material is 20 steel.
Yes, refer to page 90 of HG/T20592: mark PJ/RJ 300-10 FM 20/316
Those on the third floor can provide evidence; they are truly experts in technology
The process area used to be filled with experts, but now few people respond:(
Sure! Both the gasket flange and the loop flange are similar in structure
It’s possible; the only drawback is that the flange should ideally be painted to ensure corrosion protection in the future.
