According to CSA B 51, how often must safety valves be serviced?

The appropriate servicing interval for safety valves, as outlined in CSA B 51, specifies that these valves should be serviced every 5 years. This requirement is in place to ensure their reliability and functionality when subjected to the pressures and hazards associated with steam and other pressurized systems. Regular servicing helps in identifying any wear, corrosion, or operational malfunction that could compromise safety. By adhering to this 5-year interval, you can ensure that the safety valves will operate correctly when needed, ultimately contributing to the safe operation of steam systems and facilities. This timeframe reflects the balance between ensuring regular maintenance and the practical realities of industrial operations, providing a sound basis for establishing a maintenance schedule.
