Pressure vessels are the sealing equipment which is filled with gas or liquid, carrying a certain pressure.
The internal and external inspection of pressure vessels must be carried out only after cleaning the inside of the parking and container. The main content of the inspection is not only to include all the contents of the external inspection, but also to check the corrosion and wear of the inner and outer surfaces.
Check all cracks in all welds, head transition zones and other stress concentrations with naked eye and magnifying glass. If necessary, check the internal quality of the weld with ultrasonic or radiographic inspection.
