Questions regarding the use of ASME materials as materials for pressure vessels in China
Thread Content
According to the ‘Great Capacity Regulations’, regarding the use of materials from abroad, pressure vessel manufacturers must examine the materials that enter the factory as well as the quality certificates associated with them. They must also conduct verification tests on the chemical composition and mechanical properties of these materials; only after they meet the requirements of these regulations and the corresponding material standards can such materials be used in production. Does this corresponding material standard refer to ASME material standards or national material standards?
I think the same way; a few people in the company think it’s the national standard, and I’m speechless
Why do everyone have different understandings?
During the promotion of the \"Greater Capacity Regulations,\" (the China Special Equipment Inspection and Research Institute) stated that compliance with China’s material standards is required, such as GB 713 and GB 24511.
Thank you; there are always misunderstandings in understanding, so it’s good to have a basis.
After all, it is a domestic technical standard, so it should refer to the national standard
Complies with Chinese material standards. Can China’s standards require compliance with ASTM?
It should refer to that foreign material standard
Pay attention to the original wording of this specification: “Comply with this specification and the corresponding material standards.” The so-called corresponding material standards refer to the standards governing the origin of the material; for example, SA-516 Gr 485. In addition to meeting the requirements for materials specified in the code, it is also necessary to comply with the requirements of standards SA20 and SA516 as outlined in Part A of Volume II of ASME BPVC. Interpreting this sentence as being in line with national standards is likely a misunderstanding of the original text. Since it is basically impossible to find material grades abroad that correspond one-to-one with those specified in national standards, then which national standard should be followed?
