It’s important to note, however, that the American Society of Mechanical Engineers ( ASME) and National Board Inspection Code ( NBIC), as well as state and local jurisdictions, may set requirements for testing frequency. Be sure your company documents your relief valve testing activities. Scheduling pressure relief valve testing every six months enables you to troubleshoot issues and fix them promptly. It is recommended that you test pressure relief valves at least once every six months, especially to reduce leakage caused by the buildup of minerals and corrosion. If you consider testing pressure relief valves a maintenance task, you’ll be more likely to carry out regular testing and ensure the safety of your organization and the longevity of your boiler. Perform Regular Testing on Boiler Pressure Relief Valves Read on to learn more about each of the best practices for testing pressure relief valves.ġ.
Know when to repair or replace pressure relief valves. Perform regular testing on boiler pressure relief valves. To ensure the pressure relief valve is in good working condition, employees must follow best practices for testing them including: Pressure relief valves must be in good condition in order to automatically lower tank and vessel pressure working valves open slowly when the pressure gets high enough to exceed the pressure threshold and then closes slowly until the unit reaches the low, safe threshold. Ongoing maintenance and periodic testing of pressurized tanks and vessels and their pressure relief valves keeps them in working order and keep employees and their work environments safe. That’s also why knowing the correct way to test the valves is important. Explosions have caused far too much damage in companies over the years, and though pressurized tanks and vessels are equipped with pressure relief vales to enhance safety, they can fail and result in disaster. The valve is designed to limit system pressure, and it is critical that they remain in working order to prevent an explosion. Safety is of the utmost importance when dealing with pressure relief valves.
