Aging pressure relief valves: Are you managing history well?

The risks associated with the malfunction or blockage of pressure safety valves (PSVs) are significant, and operating facilities invest heavily in preventive maintenance (PM) programs to mitigate the risks and ensure that PSVs are functioning exactly as per design requirements.

The risks associated with the malfunction or blockage of pressure safety valves (PSVs) are significant, and operating facilities invest heavily in preventive maintenance (PM) programs to mitigate the risks and ensure that PSVs are functioning exactly as per design requirements. Significant resources are allocated to isolate, remove and transport PSVs to a workshop so that they can be returned to service as soon as possible after inspection, testing and overhauling. All field activities are controlled under strict PM programs; however, one thing that is sometimes overlooked is the preparation of traceable historical records, which is important to continuously optimize and improve the program.
