Butt Fusion is used to make pipe end to end joints. Butt Fusion joining of polyethylene pipe requires that the mating surfaces are square to each other and properly prepared. The surfaces are simultaneously heated and melted with a hot-plate heater. The hot plate heater is then removed and the melted surfaces are pressed together and held under pressure. As the molten surfaces are pressed together, the melted ends mix and once cooled, they fuse into a permanent monolithic joint which is as strong or stronger than the pipe itself in both tensile and pressure properties.
