The abovementionedcomponents of the pipe system are made from a weldable polypropylene plastic that isresistant to high temperatures, temperature changes and UV radiation. The connectionsleeves (9, 11) of the pipe coupling (4) are welded onto the pipe ends with the aid of anelectrical manual welding apparatus.
