Regarding Class E welds of pressure vessels?
Thread Content
For a pressure vessel, are the welds between its internal structural components and the inner wall of the vessel considered Class E welds? For example, in a pressure vessel, lining is required inside it. Before applying the lining, thousands of anchor bolts are welded to the inner wall of the vessel. Does this also fall under Category E welds? Surface inspection is definitely not easy at all – doesn’t it obviously make it possible to fake things?
Well, if no inspection is carried out and cracks do damage the base material, then it’s not just a matter of inspection fees anymore.
I think so too, but has anyone actually considered this? Those who have worked with incinerators know that if there are thousands of tiny anchor pins inside, it’s not practical to handle them one by one; only random inspections are possible, or fraud might occur. What do you think?
You need to understand that this is a pressure vessel, and problems with it can be much more serious than those with your incinerator.
This shouldn’t count; visual inspection shows no burrs, which is sufficient. Each issue should be addressed on its own merits……
