Finite Element Analysis to the Effect of Thermo-Mechanical Loads on Stress Distribution in Buried Polyethylene Gas Pipes Jointed by Electrofusion Sockets, Repaired by PE Patches
Polyethylene (PE) gas pipes can be jointed together by electrofusion PE fittings, which have sockets that are fused onto the pipe.Additionally, electrofused PE patches can be used to repair defected pipes.When these pipelines are buried under the ground, they can experience sever local stresses due to the presence of pipe joints, which is superimpo
