Regarding the qualifications for the design and manufacture of pressure vessels
Thread Content
For units that do not possess any level of qualification for manufacturing pressure vessels, 1: Can they manufacture vessels at atmospheric pressure and pressure vessels that fall outside relevant categories and are not subject to inspection? 2. Can atmospheric-pressure vessels and pressure vessels that are not subject to supervision and inspection be designed?
Of course. Do I even need to classify a cup I make as a special type of equipment?
It is possible, but for safety reasons, it is better for the company to have professional welders and technical experts.
1. It is possible to manufacture pressure vessels at normal pressure as well as pressure vessels that are not subject to supervision and inspection. 2. It is possible to design pressure vessels at normal pressure as well as pressure vessels that do not fall under the category requiring supervision and inspection.
Please pay attention to Section 3.2 of the General Provisions in GB150
Units that do not hold any level of qualification for pressure vessel manufacturing can manufacture vessels at atmospheric pressure and pressure vessels that fall outside relevant categories and are not subject to inspection. However, it is not allowed to design pressure vessels at normal pressure or pressure vessels that are not subject to supervision and inspection. The design of pressure vessels at normal pressure and those that do not fall under the category of pressure vessels subject to supervision and inspection must be carried out by entities holding qualifications for pressure vessel design.
