Does a new safety valve need to be tested before it can be used?
Thread Content
For new safety valves, the manufacturer conducts inspection upon leaving the factory; is it still necessary to have them inspected by a third party before they can be used? Which organizations are generally responsible for third-party testing?
Yes, it seems to be going to the local boiler inspection office
It must be inspected at a special inspection agency located where the safety valve will be used before it can be put into use.
It is necessary to go to the local technical supervision bureau for pressure setting.
It must be inspected at a local pressure vessel inspection agency before it can be used, and inspections must be carried out annually thereafter
Of course: When does a safety valve need to be calibrated? 1) Before long-term storage or before first use; 2) Regularly. It should be verified at least once a year. Inspections should be carried out at each minor maintenance cycle. 3) Valves with severe damage and rust 4) Valves with missing nameplates 5) Valves with damaged seals
The new ones are only in the first grade; they can’t reply to posts, so they get some points instead. Bye for now, hahaha!!!!
Is it necessary to remove it and send it to a specialized inspection facility for testing, or can the testing be done online?
It must be calibrated at a special inspection institute before it can be used.
The compressor we just ordered comes with a pressure relief valve set at a specific pressure, but it lacks the label from the inspection agency; therefore, it needs to be recalibrated. Since safety valves need to be registered with the local pressure vessel inspection agency, safety valves that come with the equipment generally need to be recalibrated, mainly to obtain the pressure rating label and calibration date issued by the inspection agency.
Do other countries in the world also want to send their products to inspection agencies for testing, just like our country does?
