What is the melting point of fusible plugs used as a safety device on chlorine cylinders?

The melting point of fusible plugs used as a safety device on chlorine cylinders is 163 degrees Fahrenheit. Fusible plugs are critical safety features that help prevent over-pressurization in the cylinder due to heat. When the temperature rises to the melting point, the plug melts, which allows the gas to escape in a controlled manner rather than risking a catastrophic cylinder failure. The choice of 163 degrees as the melting point is specifically designed to provide a balance between allowing the cylinder to safely vent under high heat conditions while also preventing premature melting under normal operating temperatures. This temperature is carefully selected based on the materials used in the plug and the safety requirements for handling hazardous materials like chlorine.
