Recertifying a safety valve involves inspecting, testing, and verifying that the valve still meets its original design specifications and safety standards, especially its set pressure and leak-tightness. This is a critical maintenance step in industries where overpressure protection is legally or operationally required.
Overhauling a safety valve means performing a comprehensive disassembly, inspection, refurbishment, and testing to restore the valve to like-new operating condition. It’s more extensive than a recertification and is typically done when the valve has been in service for a long time, is damaged, or has failed an inspection or test.
Pressure gauge recertification is the process of verifying, calibrating, and documenting that a pressure gauge reads accurately within its specified range and tolerance. This ensures compliance with safety standards and maintains reliable performance in critical systems.
