Electrofusion fittings

Fittings PND electrowelded
PND electrowelded fittings are a type of pipeline elements designed to connect pipes made of high-density low-pressure polyethylene (HDPE) grades: PE-100 and PE-80. Electrofusion fittings have another name - electrofusion fittings, as well as fittings with embedded electric heating element. HDPE electrowelded fittings are manufactured by injection molding or extrusion followed by mechanical processing, the raw material for production is polyethylene grade PE-100. During the production process, an electric thermistor heating element in the form of a metal spiral or wire is laid in the body of the fitting.
Polyethylene electrofusion fittings are connected to pipes or other polyethylene fittings using a special welding machine for electrofusion welding of HDPE pipes, which supplies voltage to the embedded heater, from which the inner surface of the fitting and the outer surface of the pipe are melted. The result is a strong, durable bond. HDPE electrofusion fittings are available with internal diameters from 20 to 1600 mm
