What materials are used for liquid chlorine filling and evacuation tubes?
Thread Content
Our liquid chlorine evacuation pipe is over 600 meters long; after several years of use, various blockages occur, mainly due to chlorides. What material is used for such pipes? We have also considered fiberglass, CPVC, glass-lined steel, etc., but we are not sure which one is the best; we hope everyone can share their insights.
Fiberglass is better; HPVC works too!
Our company uses both fiberglass and carbon steel pipes. The pipes used for transporting liquid chlorine to the negative-pressure pipelines of Nessler pumps were replaced over a period of about 4 years; fiberglass pipes are still in use to this day. CPVC is definitely a viable option, though its cost is much higher than that of fiberglass. There isn’t much contact between the glass lining and steel, but as long as the material is corrosion-resistant and does not react with chlorine, it should work fine.
