I need to know the national standard: should steel plates used for pressure vessels be in accordance with GB24511-2009 or GB4237-2007?

I don’t see any relevant provisions requiring that steel plates used for pressure vessels comply with GB24511-2009 or GB4237-2007; it’s possible that many steel mills do not produce such plates in accordance with GB24511-2009. So where can you buy them?

GB24511-2009 mentions... It is a stainless steel plate for pressure vessels developed with the involvement of the Pressure Vessel Committee. However, current steel manufacturers ignore this standard. In other words, the new regulations require the use of 24511 material, but since these regulations have not yet been made mandatory, manufacturers can do as they please. Even if the new safety regulations are enforced, steel manufacturers may not produce such products, and they may not be available in the market (or the production volume will be very low). In any case, most pressure vessel manufacturers currently follow GB4237 standards~~~

I have seen similar questions before. You can refer to http://bbs.hcbbs.com/viewthread.php?tid=672234&highlight=GB24511 http://bbs.hcbbs.com/viewthread.php?tid=698597&highlight=GB24511 http://bbs.hcbbs.com/viewthread.php?tid=737232&highlight=GB24511

It should be GB713-2008 Steel Plates for Boilers and Pressure Vessels http://bbs.hcbbs.com/viewthread.php?tid=406049&highlight=GB713-2008

Currently, GB24511 is required by regulations, but GB/T 4237 is also acceptable; it’s mainly the latter that is available on the market these days

Either is fine; the standard approaches differ in focus, but the content remains the same

I think it’s better to follow the requirements of 24511

In addition to demonstrating the experts’ high level of skill. . . There’s no difference. . . . . . It’s not noticeable. . .

Pressure vessels must comply with GB24511. When using GB4237, its performance parameters need to be modified in accordance with GB24511

Opinions on the Implementation of the Regulations on Safety Technical Inspection of Fixed Pressure Vessels (Quality Inspection Special Letter No. 86): The Regulations on Safety Technical Inspection of Fixed Pressure Vessels (hereinafter referred to as the Fixed Vessel Regulations) will see the end of their transition period on November 30, 2010, and will come into force officially on December 1. The following suggestions are put forward: 1. Materials (1) Regarding the materials specified in standard GB/T4237-2007. For inventory materials ordered in accordance with \"Hot-rolled stainless steel sheets and strips\" (GB/T 4237-2007), each pressure vessel manufacturer shall compare their chemical composition, mechanical properties, etc., with the technical requirements specified in GB 24511-2009, based on the quality certificates or retesting results. If they meet these requirements, such materials can be used in the manufacture of pressure vessels. Once the fixed capacity regulations are officially implemented, manufacturing units shall use materials specified in GB24511-2009 to produce pressure vessels. (II) Relevant technical measures.
