HDPE Electrofusion Fittings

Electrofusion is an electrical fusion process by which an external sleeve fitting incorporating an element is installed to poly pipe or fittings and with application of electrical current they are welded to each other. The current applied to the fitting is regulated and supplied by an electrofusion welding machine, which controls the amount of voltage, amps and welding time supplied to a fitting, in order for it to weld strongly and permanently. Electrofusion fittings are typically made from a combination of plastic and metal. The plastic component is typically polyethylene or polypropylene. The metal component is usually a metallic alloy such as stainless steel or brass. This combination of materials makes the fittings strong and durable as well as resistant to corrosion.
