Pressure vessel inspection
Thread Content
If the pressure vessel has a jacket, and the process side meets the requirements for pressure vessels, but the jacket is filled with water, it does not meet the conditions for being a pressure vessel. Is it necessary to perform regular inspections on the jacket side?
In terms of classification and management, it is treated as a pressure vessel, but the inspection requirements for the jacket are relaxed accordingly.
The requirements for regular inspection of the jacket can be relaxed...
The user can conduct inspections themselves or entrust an inspection agency; it is not a mandatory inspection item.
Inspections are also required on the jacket side, but the inspection items and standards differ; the inspection items can be determined based on the quality of the water in the jacket
