I would like to ask: What issues should be taken into consideration during the manufacturing of high-pressure vessels?
Are the high-pressure vessels you mentioned classified as Category 3 vessels? Design drawings usually specify the design codes, and it is essential to be familiar with these codes. The technical requirements are also indicated on the drawings, so they need to be paid attention to. There are usually general requirements, design requirements, assembly, welding, post-weld heat treatment, non-destructive testing, pressure testing, painting, packaging, and transportation. There are relevant specifications for each step, which must be strictly followed.
Design and manufacturing are carried out in strict accordance with standards such as GB150-1998, GB151-1999, tolerance specifications, HG20580~HG20585, H31-67, JB2768~2776, ZH200-2006, etc
A few points for design reference. If there are any omissions, please fill them in. 1. 100% flaw detection of welded joints. 2. The steel plate must be retested. Article 25 of the regulations. 3. Plates thicker than a certain thickness must be inspected by ultrasonic testing. There are also requirements regarding the supply status. See GB150 materials. 4. Overall in-furnace heat treatment is adopted.
