Does the pressure gauge on the gas source trio need to be calibrated?
It hasn’t been inspected yet, but if an HSE inspector or some expert requests an inspection, then it will have to be inspected.
It’s not necessary; no one needs to check it. It serves only as an indicator, and there are no issues related to safety or environmental protection. It belongs to category three instruments, and a one-time calibration is sufficient
Are you referring to the anemometer? It has never been calibrated; as long as it passes the factory inspection, it can be installed right away. It definitely doesn’t fall under categories A or B. As mentioned above, in our company it’s classified as category C (some people call it category 3, which means the same thing), and only one calibration is required… For a watch that costs 20 yuan each, the calibration fee isn’t even worth it……
It’s just air filtration + pressure reduction + oil mist lubrication. In many cases, air filtration and pressure reduction are combined to form an air filtration pressure reducing valve. The small gauge in question is the one located on the pressure reducing valve; it serves as a rough indicator when adjusting the pressure control knob. Many of these gauges are of poor quality – they have plastic casings, and the dial or pointer falls off even before they are used.
No, it’s only needed on the pressure vessels here
It hasn’t been inspected, nor has an inspection been requested; it falls outside the scope of mandatory inspections. Generally, local pressure gauges, as well as those related to flammable and toxic substances, fall under the category of devices that require mandatory inspection; this one does not. But don’t let it get damaged – issues like a broken watch or shattered glass should be mentioned as soon as they are noticed, haha
It’s not necessary. As long as it passes the factory inspection, that’s fine.

Only those used for safety purposes require mandatory inspection; as for whether general inspections are necessary or not, the rules are determined by oneself.
