How is excess flow control implemented in pressure systems?

Excess flow control in pressure systems is primarily implemented through shut-off devices designed for ruptures. These devices play a critical role in maintaining safety within a system by automatically stopping the flow of gas or fluid when excessive flow is detected, which could indicate a failure or rupture in the system. This proactive approach prevents potential hazards such as leaks, explosions, or fire that can occur when there is an uncontrolled release of flammable gases.

The use of shut-off devices is essential because they are specifically engineered to respond quickly to abnormal conditions, thereby mitigating risks and protecting both personnel and property in laboratory environments. In scenarios where pressure systems are in operation, ensuring that any sudden increase in flow is managed efficiently is paramount for safety compliance and system integrity.
