How easy is it to repair HDPE pipe?
HDPE is more durable and forgiving in most applications than PVC. By using proper fusion methods, HDPE does not have joints that fail like PVC. Polyethylene pipe is more flexible, and has greater impact resistance than PVC. HDPE can handle a scratch as deep as 10% of the wall thickness, without reducing the pressure rating of the pipe. PVC is notch sensitive, meaning PVC pipe has a higher inclination to fracture because of a notch, crack, or scratch. HDPE piping systems are also more surge tolerant than PVC, which means less repairs caused from pressure surges. If a polyethylene piping system is in need of repair, electrofusion couplings are one of the simplest ways to facilitate repairs. Clamp-around repair couplings, like those available from JCM Industries, offer a traditional method of pipe repair. More information on electrofusion couplings can be found by clicking here.
