Do all pressure gauges need to be tested?
Thread Content
What kind of pressure gauges need to be inspected? I know that pressure gauges installed on pressure vessels and pressure pipelines must be inspected. What about other types of pressure gauges, such as those at the pump outlet, those built into equipment, or those installed on ordinary pipelines?
All need to be tested, though some are subject to mandatory inspection, while others take a bit longer to test
Pressure gauges generally need to be inspected

It’s a small pressure gauge that doesn’t emit any sounds for alerts, nor is it involved in any automated control processes. In my opinion, it’s not essential – without it, there’s one less potential point of leakage, making the system even safer.
While that’s true, it’s important to be cautious and prioritize safety; local instruments still work well in conjunction with the inspection process. Also, to be honest, what we really lack are the reasons behind such design choices; it may require many experts in the country to discuss this, as ordinary designers don’t have much say in these matters.
**The requirements stipulate mandatory calibration only for the pressure gauges of pressure vessels. **There are no clear regulations regarding pressure gauges used in other locations. **It’s all a mess, let alone for us ordinary people. Although each pressure gauge here comes with a certification label indicating the expiration date, these labels are applied manually; when the date expires, the label is simply replaced. There is no actual calibration or verification process. Although our company has qualified calibrators and calibration equipment, it is essentially a fraudulent organization whose purpose is to issue calibration records for pressure gauges that have reached their expiration date.
Regular tables also need to be inspected; otherwise, the safety supervision department will impose penalties on you. At least that’s how it is here – it’s not possible to proceed without having the necessary certification for inspections
My wife’s company has the necessary testing qualifications, but there are too many pressure gauges to have all of them inspected upon expiration; those that are not extremely important simply have their certificates renewed when they reach the expiration date； Our company is a new factory established in the development zone; we don’t have the necessary certification for inspections, so we can only take our products to the metrology institute for testing. Since the government has prohibited charging fees, this has created difficulties for us. The municipal and district metrology institutes shirk responsibility, claiming that it’s not within their jurisdiction.
