Systematic pipe flange knowledge
Thread Content
Can anyone explain the knowledge of pipe flanges in a systematic way, such as: Regarding pipe flanges, we * * What standards are there, their relationship with the European system, the American system, and our * * the applicability of these different standards. Another example: Flanges involve gaskets, materials, flange covers, etc. . It is best to explain it systematically, and each aspect does not have to be very detailed, so that beginners can have an overall macro understanding of this. Not very grateful! ! ! ! ! ! ! !
Check out HG20592~20635. The introduction is very detailed! HG is the standard of the Ministry of Chemical Industry, as well as the petrochemical standard SH3406 and the American standard ASME B16.5. The subject of the building is too big to be introduced easily. You can go to the forum to find the corresponding standards.
