How often does ASME require low pressure steam boilers to be pressure tested?

The American Society of Mechanical Engineers (ASME) sets forth guidelines for the operation and maintenance of various types of boilers, including low pressure steam boilers. According to ASME standards, low pressure steam boilers are required to be pressure tested annually to ensure their safety and functionality. This frequent testing is crucial in identifying any potential weaknesses or issues within the boiler system that could lead to hazards if left unaddressed.

This annual requirement helps maintain the integrity of the boiler, allowing operators to take proactive steps in maintenance and repairs, which ultimately prolongs the life of the equipment and enhances operational safety. Regular pressure testing is part of a comprehensive maintenance program that yields benefits not only for safety but also for efficiency and reliability in boiler operation.
