Due to the increasing demand for using polyethylene pipes in gas distribution networks and regarding the technical specifications of transmission and suitable service condition as well as ease of implementation and installation, these materials are considered as ideal substitutes for metal pipes. Regarding the safety and economic aspects in PE (polyethylene) pipe networks before and during the operations, technical inspection is highly required. Examinations have a significant role in the safety and proper function of gas distribution PE pipes tests, because of the damage of the products and excessive costs and time are not usually affordable. Consequently, the mentioned tests are nowadays being replaced by non-destructive types and admissibility of various industries gas company in these methods is increasing. Electrofusion is a proper and fundamental technique for connecting PE pipes. In this research, the mechanism of electrofusion tapping saddle polyethylene welding has thoroughly been studied and simulated using ABAQUS software. Thermal equation of electrofusion is investigated and the results of simulation as compared with experimental results have been evaluated based on which the best qualified methods for connection have been determined and presented.
