Butt and Fusion Welding
Butt welding is a welding technique used to join PE (polyethylene) pipes together. The join is made by using hot plates to melt the ends of the pipes, then joining them together under pressure. PE pipes are commonly used for water, sewer, stormwater and power ducts instead of PVC pipes. We offer butt welding of up to 315 mm.
Electrofusion (or fusion) welding is a method of joining plastic pipes using special fittings which have built-in electric heating elements. The pipes to be joined are firstly cleaned before an electrofusion fitting is installed. Voltage is then applied for a fixed amount of time depending on the fitting used. The built-in heater coils melt the inside and outside of the pipe and the two ends are joined together.
