Which specification specifies the quality certification document for pressure vessel installation?

GB150-2011 \"Pressure Vessels\"

The quality certification for pressure vessel installation is issued in accordance with the \"Code for Acceptance of Quality of Pressure Vessel Installation\" (GB 50236-2010). This standard is a Chinese standard that specifies the requirements and procedures for the quality inspection of pressure vessel installation. .

I spent two or three hours looking into this matter, and now I have some understanding of it. The results of the current query seem to be related to historical issues. What the poster is asking about is likely the \"Quality Certificate for [Installation] of Pressure Vessels\", rather than the product quality documents related to the manufacturing process of pressure vessels. It is presumed that this certificate is required either ① when the user unit applies for a registration certificate for the use of special equipment, or ② when inspecting the quality of pressure vessel installation in petrochemical construction projects. The above two situations refer to the same thing. The original form is taken from Annex 4 of the \"Administrative Measures for the Registration of the Use of Boilers and Pressure Vessels (Replaced)\\" (Guo Jian Zhi Guo (2003) No. 207); these measures require that, when applying for a registration certificate, the user entity must submit a \"Quality Certification Document for the Installation of Boilers and Pressure Vessels\". This regulation was repealed on September 5, 2014, by the \"Rules for the Management of Boiler Use (TSG G5004-2014)\\", and was subsequently repealed on January 16, 2017, by the \"Rules for the Management of Special Equipment Use (TSG 08-2017)\“. Under the new management rules, it is no longer required to upload this file, but the relevant authorities in various regions still require its submission as part of the procedural process. As for why it is called a “boiler” rather than a “pressure vessel,” I didn’t delve into that matter; I’m new to this industry and don’t know much about the history of chemical engineering. However, the replacement of \"pressure vessels\" with \"boilers\" is perhaps a common practice, as indicated in Article 7.0.5 of the \"Code for Acceptance of Construction Quality of Static Equipment in Petrochemical Industries\" (GB50461-2008), which states that \"the unit responsible for installing pressure vessels shall issue a ‘Quality Certificate for Boiler and Pressure Vessel Installation’\" :)
