Should Fusible Plugs Be Used in Emergency Shut-off Valves in Chemical Plants?

Valve /

1. Function of Fusible PlugsFusible plugs are temperature-sensitive safety components made from low-melting-point alloys. When ambient temperature exceeds a predefined threshold (typically 70–200°C), the plug melts and triggers the emergency shut-off valve (ESV) to close automatically. This serves to: Prevent hazardous media leaks during fire or extreme heat; Protect equipment from thermal damage or explosion;
