At what temperature do fusable plugs on a chlorine cylinder start to melt?

Fusible plugs on chlorine cylinders are designed to provide a safety mechanism by melting at specific temperatures. This melting is crucial in preventing the cylinder from over-pressurizing and potentially causing an explosion. The correct temperature range for the melting of fusible plugs on chlorine cylinders is between 158° and 165° Fahrenheit.

This range ensures that the plugs will melt before the internal pressure rises to dangerous levels. When these plugs melt, they allow the chlorine gas to safely escape, thereby relieving pressure and helping to avert a hazardous situation. Understanding this safety feature is essential for operators handling chlorine to maintain proper safety protocols and ensure that the equipment is functioning as designed.

The other temperature ranges do not align with the operational standards for fusible plugs, which is why the selection of 158°-165° F is the most accurate and relevant in this context.
