At what temperature do fusible plugs designed for chlorine cylinders melt?

Fusible plugs in chlorine cylinders are designed to melt at a specific temperature to ensure safety. Most commonly, these plugs are calibrated to melt at approximately 157°F. This melting point is crucial because it allows the plug to release gas from the cylinder if the temperature rises too high, thereby preventing a potential explosion or a release of chlorine gas at dangerous pressure levels.

Understanding the function of fusible plugs is important for water operators who handle chlorine as it aids in maintaining safety during the storage and handling of chlorine cylinders. The other temperature options provided do not align with standard safety specifications for chlorination systems, thus highlighting the significance of knowing the correct melting point to ensure systems are functioning safely and effectively.
