Flange standards
Thread Content
Cannot the flanges of HGT20615 and HGT20592 be used together? And there are no plate flat welding flanges (PL) in HGT20615? Are there any fellow travelers who understand this standard?
How to connect the things from the two series? The Class series is based on US standards, while the PN series seems to be based on European standards.
With different standards, the sizes will definitely vary!
HG/T20592 belongs to the PN series and meets European standards, while HG/T20615 belongs to the CLASS series and meets American standards; both domestic standards are used in China, whereas ASME B 16.5 is generally used in foreign projects. The dimensions of HG/T20615 are the same as those of the other standard
HG/T20592 European standard, HG/T20615 American standard
The Class series is based on American standards, while the PN series is based on European standards; the American standard does not include plate-type butt welding

HG/T9115.4-2000 and HG/T20592B-2016; where can I find this 2016 standard?
