Thermoresistive welding of polyethylene pipes

Thermistor welding is called the connection of polyethylene pipes using parts with an integrated electric heater or polyethylene pipes with integrated thermos-resistant coil.

Heat-resistant welding using heat-resistant couplings is also called the electric coupling method. Heating of the pipe occurs due to polyethylene fittings, in which heating elements are laid. When the heating element, which is usually made in the form of coil, passes current, the polyethylene is melted and welded to the pipe.

Recently, composite polyethylene pipes have appeared in Ukraine, one end of which is made with a “trumpet” in which a heat-resistant coil is embedded, which liquidate the need for additional connecting elements.

Conducting hear-resistant welding requires the stripping of the surface of the sections to be joined, as well as ensuring absolute immobility of the pipes.

Heat-resistant welding is a more expensive type of connection of polyethylene pipes than butt welding. The use of this technology is advisable in cases where it is impossible to place the device for butt welding due to its dimensions.
