This post was last edited by Zhejiang Alang on 2010-10-27 at 15:24. I specialize in obtaining certification for pressure vessels; based on your current situation, my personal advice is as follows: 1. If it’s a low-pressure, simple pressure vessel, it is recommended to obtain a manufacturing qualification certificate for Class D1 simple pressure vessels. In this case, there is no need to set up a flaw detection laboratory – only blast testing is required, which makes the process simpler. II. If it is not a simple pressure vessel, it is recommended to use Class D1/D2. As for how to determine this, a brief overview of the requirements is as follows: 1. Establish a qualified inspection room and obtain environmental protection certifications, that is, apply for a radiation safety license ； 2. Contact the welder examination committee and organize more than 6 welders with extensive welding experience to take exams in shielded metal arc welding, gas tungsten arc welding, carbon dioxide gas shielded welding, and submerged arc automatic welding, in order to obtain welder qualification certificates (the list of examination subjects will be determined based on the company’s product requirements). 3. Establish a summary table of qualified certified welders in the company, as well as records for these certified welders. 4. Establish a primary weld material warehouse, a secondary weld material warehouse, and a dedicated storage area for the welding laboratory (the required equipment will be listed separately based on the company’s specific conditions); maintain records of the weld material inventory. The warehouse manager shall record the relative humidity in the primary weld material warehouse on a daily basis, and keep track of the baking and temperature control processes for electrodes and fluxes in the secondary weld material warehouse. 5. Formulate management regulations for the primary weld material warehouse, the secondary weld material warehouse, and the welding laboratory, and post them on the walls. 6. Prepare welding procedure qualifications based on the company’s products, and establish a summary table of the company’s welding procedure qualification items. 7. The requirements for equipment needed to obtain certification for manufacturing Class D pressure vessels state that compliance with production requirements is necessary, but these specifications are rather vague. Generally, the following should be considered: a. The crane used in the main workshop should ideally have a capacity of over 5 tons; b. The thickness that can be rolled by the sheet rolling machine should be at least 12 mm. If both stainless steel and carbon steel are to be processed, two such machines are required; c. For welding, it is sufficient to have a sufficient number of DC and TIG welders; one welding laboratory is also required; d. At least one submerged arc welding machine is necessary; e. As for roller frames, plasma cutters, etc., any appropriate number will suffice; f. There are no mandatory requirements regarding other precision machining equipment such as sheet cutting machines, lathes, milling machines, and grinders, but having a few of them would be useful. . . . . . . . . . Since the process of obtaining certification involves many complex tasks, in addition to requiring technical expertise that is comprehensive, it also demands organizational skills and the ability to express ideas in writing. I will not go into detail here; those who need advice can contact me directly. I hold a bachelor’s degree in Chemical Equipment and Machinery from a 211 Project university and hold the title of engineer. I have long been involved in the design, manufacturing processes, welding techniques, and quality assurance work related to pressure vessels. I am familiar with the quality assurance systems for pressure vessels, and in particular, I have extensive experience in the process of obtaining certification for pressure vessel manufacturing – from setting up inspection rooms and applying for environmental permits to coordinating with expert teams for on-site evaluations at companies. I welcome inquiries from individuals and other companies involved in pressure vessel manufacturing. Contact details: 1. Engineer Wu, 135 8841 9760 / 138 1603 5040; 2. QQ: 894373799
