A Lifetime Prediction Method of Pressured Gas Polyethylene Pipes by Thermal-Oxidative Aging Test and Tensile Test

Polyethylene (PE) pipes have the advantages of low weight, corrosion resistance, high impact resistance, and superior flexibility, and have been widely used for various urban gas engineering. With the increase of service life, the aging of PE pipes has become a safety issue that needs to be solved. So far, the aging performance of PE pipes are researched at home and abroad, but there are few reports on the aging performance of PE pipes under...
