A pipe does more than just convey industrial liquids from one location to another. It must also be corrosion and abrasion resistant. It must be flexible and easy to install, and maintain a high flow coefficient throughout its service life of 50-100 years. And it must not leak.
With polyethylene pipe, you get all of these benefits. Because of the hazardous nature of some chemicals being transported, it is imperative that the system not leak. Heat fusing polyethylene pipe produces a leak free joint that is as strong if not stronger than the pipe itself in tension and pressure applications. These joints are self restrained. They need no thrust blocks or restraint harness except where the pipe attaches to a non-polyethylene system.
