Polyethylene pipe is important for the transportation of gas

water supply and drainage. However

the diversification of the service environment leads to the inevitable aging of polyethylene pipes. Therefore

it is very important to study the aging behavior of polyethylene pipe aging in different environments and how to prolong its service life. This paper introduces the influencing factors of aging of polyethylene materials

the main mechanism of aging of polyethylene pipes and the main research methods of aging of polyethylene pipes. The recent research progress on the thermal aging behavior and stress cracking behavior of PE pipes has been reviewed. It is of great importance for prolonging the service life of PE pipes

and it provides a reference for the application of PE pipe in engineering field.
