HDPE pressure pipeline has been widely used for its excellent properties in gas, water supply and other fields. However, lack of knowledge and research on damage behavior of HDPE pressure pipeline has resulted in the shortage of safety requirements for equipment engineering. This paper summarizes the research progress of the two main damage modes of HDPE, i.e., aging damage mode and stress damage mode, and expounds the damage mechanisms, evolution processes and influencing factors. It also reviews the existing research problems and looks ahead the future research direction in special equipment engineering.
