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 hazardous, 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
I also checked it after seeing you; I don’t have such detailed classifications here – everything is categorized by half-year periods. There’s a passage I found online; take a look to see if it’s useful
Don’t mislead people; generally, pressure pipelines do not require calibration, while pressure vessels and boilers do.
Check whether it is a pressure gauge on a pressure vessel or pressure pipeline; if so, the inspection is usually done every six months (and it is now free of charge)
We don’t make such detailed distinctions here; everything is grouped together on a semi-annual basis
Isn’t there a lot of waste there? It definitely needs to be handled in stages, right?
Do you think that the pressure gauges on pressure vessels and pipelines are the only instruments that require mandatory calibration? Is the pressure gauge at the pump outlet a process control pressure gauge, and can it be used as a Class B pressure gauge?
It is necessary to check whether the pressure pipeline at the outlet of your pump falls under the category of pressure pipelines. If it does, mandatory inspection is required; currently, such inspections are provided free of charge, so it’s fine to declare a slightly higher amount.
Who will end up paying for it? If it’s free, who would engage in a business that doesn’t generate any profit?
Indeed, there isn’t such a detailed classification, but the company conducts uniform half-yearly inspections
