The technical specifications for CD130A19-85 fiberglass-reinforced plastic equipment designed using the hand-laying method are really outdated. I’m not sure what the new standard that replaces it is; some people say it has been replaced by HG/T 20696-1999, the specifications for the design of fiberglass chemical equipment. However, HG/T 20696-1999 itself does not state that it replaces the former standard; moreover, the scope of application for these two standards is different – the former applies to the \"hand lay-up method\", while the latter is applicable to \"mechanical winding\". Welcome everyone to discuss; thank you for participating!
