The issue of the inspection cycle for pressure gauges used in pumps
Thread Content
First, I read many posts and understood that pressure gauges need to be classified into different grades, with varying inspection cycles for A, B, and C categories. So which category does the pump outlet pressure gauge belong to? Is there any difference if the medium pumped by the pump is liquefied gas or a highly corrosive medium, as opposed to water? This is because one of the requirements for Category A mandatory inspections is: g, measurement of pressure for harmful, toxic, and highly corrosive media. (For example: Bourdon tube pressure gauges, electric remote transmission pressure gauges, and electrical contact pressure gauges) Please help me understand this
If the medium being transported is water, Category C can be designated. Of course, it also depends on the importance of the equipment in the process. It would be inappropriate to classify a pump used in a fire protection system as Class C!
