What is the requirement for the connection of safety valves or safety relief valves to a boiler?

The requirement for the connection of safety valves or safety relief valves to a boiler is that they must be attached close to the boiler. This is crucial to ensure their effectiveness in protecting the boiler system. The proximity of the safety valve to the boiler allows for immediate response in case of overpressure, enabling the valve to open quickly and relieve pressure without delay. This is vital for preventing potential damage to the boiler and ensuring safe operation.

In addition, placing the valve close to the boiler minimizes the length of the pressure line, reducing the risk of pressure buildup or fluctuations that can occur in longer connections. It also simplifies the path for steam or fluid to escape, thus enhancing the reliability and speed of the safety mechanism.

Other connection methods, such as using long pipes or various fittings, can introduce factors that may impede the valve’s performance and reaction time, which directly compromises the safety function intended for the system.
