As industrial machinery and equipment, regular inspection and maintenance are essential for PSA nitrogen generators. However, whether it is a small problem or a major failure, safety awareness must be firmly grasped. Taking the inspection of pressure pipelines as an example, there are several places that are easily neglected and need to be vigilant;

When the staff is inspecting the pressure pipeline, they must first be very clear that the pipeline is in a "pressurized" state, and remember not to tighten the screws on the pipeline; this is because in pipeline inspections, the most common situation we encounter is pipeline leakage; the cause of the leakage may be gasket damage, thermal stress on the pipeline, etc.; but the staff just want to simply tighten the screws, not only can not solve the leakage problem, but also may cause the bolt to break due to insufficient estimation of the bolt force, so that the high-pressure gas in the pipe will be ejected, causing serious safety accidents. In fact, this situation is not an isolated case. There have been several accidents in the industry, which are painful lessons of injuring people because of the bolts being screwed off under pressure, resulting in the flying of the flange.

Therefore, no matter who is doing the pressure pipeline inspection at any time, they must keep in mind the operating procedures and strictly abide by the operating specifications; they must not rush the time and take chances in the inspection of "pressure pipelines". Safety production is no small matter, and in many cases, slow is fast.
