External Inspection Of Pressure Vessel

It is also called in-operation inspection. The main contents of the inspection include: whether there are any abnormal phenomena such as cracks, deformation, leakage, and local overheating on the outer surface of the pressure vessel; whether the safety accessories are complete, sensitive and reliable; whether the fastening bolts are intact and all tightened; Whether the foundation is sinking, tilting, and whether the anti-corrosion layer is damaged or not, etc. External inspection is not only the job of the inspector, but also the routine inspection item of the operator. Safety-critical phenomena (such as cracks, deformation, serious leakage of pressure components, etc.) should be stopped and the relevant personnel should be reported in time.
