Abstract

The device is assembled of two pipe sections joined along one of their edges by welding (11). The material of one of the pipes is corrugated (14) or formed into a helical shape in order to compensate axial and lateral motions. The second segment has longitudinal grooves (13) to suitable for absorbing torsion forces. In a second version the device is made all in a piece with two differently shaped areas (13, 14), and a third version consists of one segment with an extension to be inserted into the second segment for joining the two parts.
