The Effects of Chlorinated Water on Polyethylene Pipes

Chlorine chemistry is complex. Under certain common conditions, chlorinated compounds can react with polyethylene pipes causing premature failures (bursts/leaks). It is important to understand this degradation mechanism in order to prevent future premature pipe failure. Recently, a specific additive system, when incorporated into polyethylene pipe resin was demonstrated to significantly improve the pipe’s resistance to degradation caused by chlorine exposure.
