TS Certification for Pressure Pipeline Valve Manufacturing License
Thread Content
I would like to ask the teachers: Under the new standards for the licensing levels for pressure pipeline valve manufacturing, is it not necessary to obtain a license for pressure levels of 4.0 MPa and below?
To obtain evidence, levels below 4Mpa should correspond to Class B
Literally, there is no need to collect evidence
Under the new **regulations**, special equipment manufacturing licenses are divided into Class A and Class B: those with a pressure of over 10 MPa fall under Class A, those with a pressure between 6.4 and 10 MPa fall under Class B, and those with a pressure below 4.0 MPa do not require a license
If you need to obtain evidence, you can come to me
