At what pressure does a boiler become classified as a "High temperature water boiler"?

A boiler is classified as a "High temperature water boiler" when it operates above 160 pounds per square inch (psi). This classification is important because it indicates the potential hazards and safety concerns associated with high-temperature, high-pressure systems. Operating at such pressures increases the risks of mechanical failure or catastrophic incidents, which necessitates stricter regulatory compliance, maintenance procedures, and operator training.

The threshold of 160 psi signifies a key difference in operational practices, safety protocols, and design specifications between standard boilers and those deemed high temperature. Understanding this classification helps boiler operators ensure they are adhering to appropriate guidelines and safety measures when managing and operating high-temperature systems.
