ABSTRACT:
The method for preventing the propagation of cracks in plastic pipes consists substantially in that at predetermined locations of the tube sections of reduced diameter are foreseen, but to provide these sections with a view of reinstating the static strength simultaneously with a reinforcement which does not form a homogeneous compound with the material of the tube. This is made preferably by application of a correspondingly designed crack stopping element between to tube ends or by inserting such a element between same.
