EXTRUSION WELDING

 

The pipes and/or fittings which shall be connected are jointed by a socket and spigot joint. Thus the two pipe ends are connected with the help of an extrusion welding device. The jointing method can be carried out inside or/and outside of the pipe. This jointing is most suitable for low-pressure gravity pipes and manholes.
 
The welding has to be done according to DVS 2207 part 4.
