What is the best type of gasket to use when connecting a chlorine cylinder or container to the chlorine feed system?

The best type of gasket to use when connecting a chlorine cylinder or container to the chlorine feed system is a lead gasket. Lead gaskets are designed to effectively seal connections in systems handling chlorine and other corrosive gases because they can form a tighter seal than many other materials. The nature of chlorine gas, which is highly reactive and can lead to corrosion, necessitates a material that will not only provide an effective seal but also withstand the corrosive effects over time.

Lead gaskets offer excellent chemical resistance and can compress well to eliminate the potential for leaks at the joints, which is critical in preventing the release of chlorine, a hazardous substance. Furthermore, the malleability of lead allows it to conform better to irregularities in surfaces, ensuring a more secure and durable seal.

In contrast, rubber gaskets may degrade when exposed to chlorine, plastic gaskets may not withstand high pressure or temperature conditions associated with chlorine gas systems, and foam gaskets generally do not have the necessary strength or chemical resistance needed for such applications. Choosing the appropriate material for gaskets is essential for the safe operation of chlorine feed systems in water treatment facilities.
