Polyethylene hot-wire butt welding fasteners
Cast fittings are made by thermoforming on specially equipped injection molding machines.
The connection of the cast fittings to the pipes is done by butt welding, and in some cases thermistor welding can be used.
Fittings have various standard sizes and are intended for the assembly of pressure and non-pressure pipelines (branches, route diameter changes, connecting pipe fittings).
