Supervision and inspection of pressure vessels.

This post was last edited by WANGJIABAO on 2017-7-13 at 15:40. Inspection for manufacturing supervision was carried out on the pressure vessel heads; the pressure vessels using these heads are not covered by the regulations regarding large capacity vessels. What should be done in such a situation?
After this end cap is used, a supervision and inspection certificate is no longer required; copies need not be provided to the client, and the documents related to the production process should be organized and archived accordingly.
The entire equipment does not require inspection, but it would be better to inspect components such as end caps, right? Of course, this will increase costs, but the quality will be ensured.
I don’t understand what exactly you are trying to ask
The purchased end caps were subject to manufacturing inspection; they are bought for use in atmospheric or vacuum vessels, and since the entire vessel does not require inspection, what should be done with the inspection documents for the end caps?
It’s indeed a bit of a waste; there is a difference in price depending on whether inspection is included or not. Then archive it together with the head certificate......
