Pressure vessel safety valve
Thread Content
The company has installed a new air compressor. There is a simple pressure vessel in the air compression system, and the safety valve that was installed is a new one. Can this type of safety valve be used directly? The safety valve does not have a inspection tag
Safety valves need to be regularly calibrated and must not be used beyond their calibration period.
The new safety valve should also be checked to see if its calibration has expired.
Safety valves must be inspected before they can be used
Verification shall be carried out based on the operating pressure of the simple pressure vessel; it must not exceed the design pressure of the simple vessel or the maximum operating pressure indicated thereon
It must be tested before use. Technical documents and factory information are complete
Safety valves, whether new or old, must be inspected before use.

It must be sent to a local inspection agency or a unit qualified for calibration in order to have its pressure adjusted and fitted with a label before it can be used
