Because of its flexibility, toughness and good resistance to corrosion and abrasion, polyethylene has been widely used as a material for making pressure pipes, corrugated pipes for decades in a variety of applications, including gas and water distribution, oil and gas collection, and many industrial pipe segments. Dane Chang and Carl Baker conducted a study, finding that a significant limitation to polyethylene pipes in this application is its temperature capability. Typical, polyethylene pipe can be safely used at temperatures up to 60 ° C (140 ° F).

There is a projects that has been involve of higher temperatures can historically require alternative materials. High density polyethylene (HDPE) bimodal resins with a pressure rating of 82 ° C (180 ° F) have recently been developed for demanding pipe applications. This resin qualifies in the highest pressure rating category with a list of ISO PE100 and ASTM PE4710. In addition, it has excellent resistance to slow crack growth and fast crack propagation. This expands the capabilities of traditional polyethylene materials to a more severe service environment and has been used successfully in North American oil and gas collection and transportation applications in solid walls and composite pipe structures. The main physical properties and performance will be discussed.
