Defect repair of pressure vessels in use

Help needed: defect types and repair methods for pressure vessels in use.
What exactly are the defects? It’s not possible to give a general answer; each issue needs to be analyzed individually in order to develop a detailed plan. Asking it this way makes it hard to answer.
For different types of defects such as corrosion, cracks, hydrogen bulging, etc., there are various repair methods. Even once the specific type of defect is identified, the repair approach still varies depending on the specific conditions of the container; it is necessary to determine the exact circumstances.
It is still advisable to refer to the PCC-2 standard, as it provides some principled guidance. http://www.doc88.com/p-5029759634019.html
