What is the recommended interval for testing safety valves set between 15-400 psi?

The recommended interval for testing safety valves set between 15-400 psi is monthly. This frequency is necessary to ensure that the safety valves function correctly and can provide the needed protection for the boiler system. Safety valves play a critical role in maintaining system pressure and preventing overpressure conditions, which can lead to dangerous situations such as explosions or equipment failure.

Regular monthly testing allows for the early identification of any malfunctions or wear that could hinder the valve’s operation. It ensures that the valves can release pressure effectively when needed. Adhering to this monthly schedule is aligned with best practices and regulatory requirements within the boiler industry, emphasizing the importance of maintaining safety and reliability in boiler operations.
