Do all safety valves need to be calibrated?
Thread Content
In accordance with regulations regarding special equipment, including the safety valves attached to it, regular calibration is required. However, do safety valves on ordinary equipment or non-pressure pipelines (vessels) need to be calibrated? Safety valves for general engineering projects are typically calibrated at 100%, yet there is no regulatory basis for this. . .
Whether the safety valves of ordinary equipment or non-pressure pipelines (vessels) need to be calibrated depends mainly on the safety standards for using such equipment and the regulatory requirements. If relevant regulations or standards explicitly require verification, then verification must be carried out ； If there is no explicit requirement, it is generally recommended to determine whether calibration is necessary after evaluating the operating conditions of the equipment and the associated safety risks. Conducting 100% verification in the absence of regulatory basis is more driven by safety considerations. .
Safety valves themselves must be calibrated in accordance with special equipment regulations, regardless of the equipment to which they are installed.
100% verification is aimed at ensuring perfection. Safety first. Even standards should be as such.
According to the regulations on the management of special equipment, safety valves must be calibrated.
The actual operation involves 100% verification.
