High density polyethylene (HDPE) pipe has many advantages over metallic pipe, and has been used innon-safety related application for years in some nuclear power plants (NPPs). Recently, HDPE pipe wasintroduced into safety related applications. The main difference between safety-related and non-safetyrelated pipes in NPPs is the design method of extra loadings such as gravity, temperature, and earthquake. In this paper, the mechanical behavior of HDPE pipe under various loads in pipe gallery wasstudied by finite element analysis (FEA). Stress concentrations were found at the fusion regions on innersurface of mitered elbows of HDPE pipe system. The effects of various factors were analyzed, and theinfluence of various loads on the damage of HDPE pipe system were evaluated. The results of this paperprovide a reference for the design of nuclear safety-related Class 3 HDPE pipe. In addition, as the HDPEpipes analyzed in this paper were suspended in pipe gallery, it can also serve as a supplementaryreference for current ASME standard on Class 3 HDPE pipe, which only covers the application for buriedpipe application.
