Pressure vessel audit level
Thread Content
My friends, please fill in the "Category II (Level A2)" in the container category in the pressure vessel data sheet. Category II is classified according to the grade in the capacity regulations. At the same time, the manufacturing unit must have a manufacturing license for no less than Category II vessels. Is Grade A2 a requirement for review? If not, what category does it refer to? ； If there are several levels, what are they? Please help Haiyou.
I've never seen anyone fill in categories like this. Does it mean design or manufacturing qualifications? Introduce the equipment situation
The A2 level specified in the Pressure Vessel Pipeline Design License Rules and the Pressure Vessel Manufacturing Supervision and Administration Measures refers to the third category of low and medium pressure vessels. And your report is Category II, which...
Maybe I didn't ask clearly. According to the container design categories, they are divided into Class A, Class C, Class D, and Class SAD. I know this, and Class D2 is definitely the second class, but is it necessary to write "Class II (Level D2)" like this? Is it to highlight the level of review? Or just write "Category II" or D2 level.
If it is a drawing, you should only write Level II A1, A2, D2, etc., which represents the company’s design and production certificate.
Just fill in Level II on the drawing
Design categories and levels are divided into two categories: Pressure vessels and pressure piping. Classification of pressure vessel design categories and levels: 1.A1 level 2.A2 level: Refers to the third category of low and medium pressure vessels. 3.A3 level 4.A4 level and above are category A. Category C is divided into three levels ； Category D is divided into two levels ； The SAD class is for analysis and design.

Generally, the quality certificate issued by the manufacturer needs to highlight A1, A2, A3, etc., and A1 must also indicate multi-layer, single layer or winding. Because the manufacturing qualifications of these projects are separate, cross-project production is not allowed. However, the drawings issued by the design institute do not care about these and only write Class I, Class II and Class III. The data sheet you are talking about should be part of the quality certification document issued by the manufacturer. Then please indicate A2 as required in the former.
I understand, because our unit is a pressure vessel manufacturer, marking A2 or D2 is related to our manufacturing qualification. If you obtain the A2 qualification, you can manufacture pressure vessels below D2 level, and only the container category can be marked on the drawing. Thank you, everyone.
