Regarding the issue of expired calibration validity periods for safety valves
Thread Content
Our company has over a hundred safety valves, and some of them cannot be removed during operation. If our facilities continue to be in use after the expiration date of those safety valves, it becomes impossible to have them inspected in a timely manner. However, we have internal procedures that allow for delayed inspections to be carried out. Is this considered a violation? Will there be any penalties if inspections reveal that these valves are past their expiration date? There are no relevant regulations regarding this matter
An application for extension must be approved by the local quality supervision bureau. While such an approach may work effectively within the factory itself for the company’s purposes, it is ineffective from the perspective of special equipment regulation. Prepare the application and relevant documents, and submit them to the company’s equipment department so that they can handle the extension process with the local quality supervision bureau
The safety supervision department is concerned with the outcomes; if anything goes wrong as a result, it is they who will be held responsible. No matter how many reasons you have, you should focus on this. For a company, solving this problem is no easy task. First, a stop valve should be installed in front of the safety valve for testing it. Pressure testing can be carried out online, or by replacing the safety valve for testing. If it wasn’t installed in the original equipment, it’s a problem of the designer or supervisor. Regarding safety supervision departments, it is necessary to practice diligently and communicate frequently; giving reasons is not a viable approach.
I contacted an online verification service, and the cost was about ten times higher than that of doing the verification in person.:
