Regarding the issue of obtaining a pressure vessel manufacturing certificate.
Thread Content
Our company plans to obtain the manufacturing licenses D1 and D2 for pressure vessels this year, and I have been assigned to handle the related documentation. Until now, I have only been involved in the design of pressure vessels, and with only two years of experience, my knowledge is quite limited. The information available online is also very scarce; I hope that experienced colleagues can offer me some guidance. Thank you very much. The main issues are: 1. The personnel required, 2. The equipment needed, 3. The document systems required. I haven’t thought of anything else yet; I hope everyone can help me come up with some ideas. Thank you!
Take a look at Document No. 194 issued by the General Administration of Quality Supervision, Inspection and Quarantine; there are regulations in it.
Take a look at Document No. 194 issued by the General Administration of Quality Supervision, Inspection and Quarantine – the requirements for obtaining a license to manufacture boilers and pressure vessels, as well as the procedures for such licensing; it’s all quite clear there. Wish you success in obtaining the certification soon. :victory:
However, nowadays, most people apply for the manufacturing certificate for type A2 vessels (medium and low pressure, category 3), and the initial investment required is not much higher than that for type D2 certificates. If you want to obtain evidence, you can first consult the local special inspection agency; of course, it’s best to have good relationships with them, as that will make things go much more smoothly.
You can go there; the General Administration for Quality Supervision, Inspection and Quarantine will tell you what technical requirements and standards apply, and you just need to follow those requirements. That’s all. If you can’t meet his requirements, then you’re not good enough.
Reference standards: the \"Regulations on the Safety Supervision of Special Equipment\" (Decree No. 373 of the State Council), the \"Measures for the Supervision and Management of Boiler and Pressure Vessel Manufacturing\" (Decree No. 22 of the General Administration of Quality Supervision, Inspection and Quarantine), the \"Basic Requirements for Quality Assurance Systems in the Manufacturing, Installation, Modification, and Maintenance of Special Equipment\" (TSG Z0004-2007), and the \"Detailed Rules for the Assessment of Licenses for the Manufacturing, Installation, Modification, and Maintenance of Special Equipment\" (TSG Z0005-2007). In addition, the necessary resource conditions must be met in order to establish a quality assurance system
The staff are much better now; quality assurance engineers don’t need to take exams and can be appointed directly. The other type of engineers include those in charge of materials, quality inspection, non-destructive testing, pressure testing, equipment, processes, welding, and physical and chemical analysis. The documents are even simpler – just prepare a warranty manual, along with management documents, procedure documents, process documents, and a compilation of forms and cards. Then organize the site and divide it into areas according to the manual’s specifications. It’s possible to find a manufacturer to modify the relevant documents to resolve the issue, and finally, produce a prototype of the equipment. The key is to use connections!
1. Standards: TSG Z0004-2007 \"Basic Requirements for Quality Assurance Systems in the Manufacturing, Installation, Modification, and Maintenance of Special Equipment\" and TSG Z0005-2007 \"Detailed Rules for the Assessment of Licenses for the Manufacturing, Installation, Modification, and Maintenance of Special Equipment\"; all details specified in these standards must be followed. 2. Personnel: There are nine roles for responsible engineers, namely those in materials, quality inspection, non-destructive testing, physics and chemistry, equipment, processes, welding, site management, and quality assurance. At least 5 people are required, with the position of quality assurance engineer having to be held by someone with an engineering degree or higher ； The workers should include several cold-working specialists, as well as several certified welders with the necessary qualifications. 3. Site: Divide the workshop area and designate a specific space (approximately 1000 m2), in accordance with the provisions in the manual. 4. Equipment: There should be edge trimmers, rolling triggers, welding machines, automatic welding machines, machines for testing physical and chemical properties, flaw detection rooms, as well as various machining devices.
In accordance with the requirements of the \"Basic Requirements for Quality Assurance Systems for the Manufacturing, Installation, Modification, and Maintenance of Special Equipment\" (TSG Z0004-2007) and the \"Detailed Rules for the Assessment of Licenses for the Manufacturing, Installation, Modification, and Maintenance of Special Equipment\" (TSG Z0005-2007), a quality assurance system shall be established, and appropriate responsible engineers shall be appointed.
It was explained very clearly on the 6th floor; basically, there are 3 regulations that serve as the basis for obtaining certificates. Where are you from? If you’re in Jiangsu, it’s easier to get an A2 certificate than a D-level certificate. I’ve helped people obtain certificates for several companies already. Feel free to contact me if you need any help
I’m not quite sure about pressure vessels. The license for manufacturing pressure pipeline components is generally granted by evaluating enterprises from two aspects: one is the enterprise’s own conditions ； Second, a corresponding type test certificate is required
