Making connection ends on metal pipes involves placing pipe ends in annular grooves of essentially cylindrical connecting pieces, pressing circumferences together with connecting pieces

摘要

The method involves placing the ends (2a) of the piece of pipe (2) in annular grooves (6) of essentially cylindrical connecting pieces (5) and pressing their circumferences together with the connecting pieces. The pipe ends can be inserted into the grooves with additional elements such as damping elements and pressed together with the connecting pieces. Independent claims are also included for the following: a connecting piece for making connection ends and a line element.
