Valve production license

Thread Content

I would like to ask everyone: Is a pressure vessel production license required to design and manufacture gate valves with a design pressure of 20 MPa? Do designers need a qualification certificate for pressure vessel design? Can the company handle getting the design qualification certificate instead? What things are needed?

Designing and manufacturing gate valves with a design pressure of 20 MPa does not require a pressure vessel production license. Instead, obtain a production license for pressure pipeline components. Valves do not require a design license.
