Issues regarding the classification and inspection of pressure vessels
Thread Content
I’m a newcomer, and I encountered some uncertainties regarding the inspection requirements for pressure vessels. I heard someone say that inspections aren’t required for certain types of pressure vessels; is this only the case for Class I pressure vessels? Are there any situations where inspections aren’t necessary for Class II pressure vessels as well? Under what circumstances are Class I pressure vessels subject to supervision and inspection? I hope you can give me some advice; it would be great if you could provide some specific examples. Thank you!
Does the upper category refer to classification? Containers of categories I, II, and III all require supervision and inspection. Containers classified into these categories mean that they are subject to the regulations set out in TSG R0004-2011 \"Regulations on Solid Pressure Vessels\"; you can take a look at this document.
What was said upstairs is correct. Pressure vessels are special equipment. All are subject to supervision and inspection by the boiler inspection agency
For a 20L air storage tank with a design pressure of 9.8 MPa and an operating pressure of 9.0 MPa, according to clause 1.4.2 of the Code for Fixed Pressure Vessels, no supervision inspection during the manufacturing process is required.
As long as the regulatory requirements are met, classification is required, but inspection is not necessarily necessary. Containers falling under Article 1.4.2 of the regulations do not require inspection, regardless of the pressure level? Is an example even needed? It is a container with a volume of 24.9 liters; even at a pressure of 99 MPa, it does not require testing, but it needs to be classified. Got it?
I think I understand a bit now. Could someone give an example? A vessel that falls under Category I pressure vessels still requires supervision and inspection. Thank you
