Issues regarding the calibration of safety valves in centrifugal compressors
Thread Content
Hello, teachers. I have a question I would like to ask. Our company is involved in long-distance pipeline transportation, and we have foreign-made centrifugal compressor units installed at the compression stations; we are currently facing a problem. Do the safety valves installed on the compressor dry gas seal disk and lubricating oil system need to be regularly calibrated on-site? Online or delivered locally? Are there any relevant mandatory regulations? I always feel that testing good products is a way of ruining them; besides, there are no spare parts for safety valves either. I couldn’t find any information online either; I’m asking the teachers here if they have any experience with this
This safety valve certainly isn’t of the type that can be switched between three modes, right? Talk to the special inspection agency; it would be best if they could provide only a report without requiring the item to be sent for inspection. We’re also reluctant to send our imported high-pressure safety valves for calibration, as they are very delicate and we’re afraid they might get contaminated
