Safety Precautions for Inspecting Gas Piping in PSA Nitrogen Generators

As industrial equipment, routine inspection and maintenance of PSA nitrogen generators are essential. However, whether addressing minor issues or major malfunctions, safety awareness must remain paramount. When inspecting gas piping, several easily overlooked aspects require special vigilance:

During gas pipeline inspections, personnel must first confirm that the piping remains in a pressurized state. It is crucial to avoid tightening any pipe fittings under pressure. The most common issue encountered during inspections is gas leakage, which may result from damaged gaskets, thermal stress, or other factors. Attempting to simply retighten fasteners not only fails to resolve leaks but also risks improper bolt loading, potentially causing bolt fracture. This could lead to high-pressure gas suddenly venting, creating a severe safety incident. In fact, such occurrences are not isolated cases; the industry has witnessed multiple accidents where pressurized bolts were broken, causing flanges to become projectiles and resulting in serious injuries.

Therefore, regardless of personnel or timing, strict adherence to operating procedures is mandatory during gas pipeline inspections. Never compromise on safety protocols for the sake of expediency. There are no trivial matters in safety production; often, adopting a cautious approach equates to true efficiency.
