Article

Aspects of the use of effective hardware for thermistor couplings and components, which are used for thermistor welding in the repair of low- and medium-pressure polyethylene pipelines are investigated. Parameters of thermistor welding, and namely, the limiting values of the electric resistance, welding time, welding voltage, and the time required to cool the butt joints, are analyzed as a function of the diameter of the polyethylene pipelines and the type sizes of the connecting thermistor couplings or components.
