At what temperature does the fusible plug on a chlorine cylinder melt?

The fusible plug on a chlorine cylinder is designed as a safety feature to prevent the cylinder from rupturing due to excessive heat. The melting point of the fusible plug is typically around 156°F to 165°F. This temperature range is critical because when the temperature exceeds this threshold, the plug melts, allowing chlorine gas to safely escape and thereby reducing the pressure within the cylinder. This mechanism helps to avert a potential explosion caused by high pressure.

Understanding the temperature range for the fusible plug is essential for operators handling chlorine cylinders, as it is a vital part of maintaining safety protocols in environments where chlorine is stored and used. The specified range of 156°F to 165°F effectively balances the need for operational safety and the properties of chlorine gas under various temperature conditions.
