Electrofusion (EF) joints have been widely used as easy-to-fuse and high-quality joints for joining polyethylene (PE) pipes. When we introduced EF joints 150 mm or more in diameter, an electrofusion simulation program was concurrently developed to reduce time for design and experimental works. It was verified that the simulation results calculated by using the program agreed well with the experimental results. This paper describes the features of the program and its application to EF joints developed for the casing pipes of district heating and cooling pipelines and to the design of EF joints based on the revised JIS.
