A newcomer seeking advice: what are the main differences between China’s flange standards, Europe’s DIN standards, and the United States’ ASME standards? Please help me out, experts{:1_90:}!
The domestic standard HG20592 is actually equivalent to the European standard, while HG20615 corresponds to the American standard. For round shapes, imperial measurements are used, and if you look closely, there are differences between them. It is also mentioned in the preparation notes
Personally, I think chemical industry standards should follow national standards; why create so many standards? It’s necessary for the vast majority of key dimensions to be the same. At most, in special cases or situations where there are specific requirements regarding materials and strength, that should not affect the use of standardized components across everyone. Now, with this sudden requirement from HG, it’s necessary to study the standards to see if they can be integrated with GB standards. .
Thank you, there are so many standards that it’s overwhelming!
Standards are also the technical outcome of a particular industry, as well as the result of negotiations among various industries. I think HG20592-HG20615 are quite comprehensive; by looking at the explanations provided for these standards, one can see the effort that went into their development
I agree to the above floors; the specific usage will depend on the owners’ requirements
There aren’t many commonly used domains; they are mainly PL, SO, and WN. PJ and RJ are primarily used for stainless steel and precious metals, and they aren’t often used in factories. You’ll understand better if you see the actual products on site. All ANSI ones have a neck or high neck, and the pipes are of the imperial type with decimal markings. Both types of pipes meeting European standards can be used.
