Verfahren zum Verbinden von Leitungen

摘要

The method involves connecting one end (2) of the pipe to an adapter (1) of a connection device such as a quick-connector, through friction welding and controlling the build-up area of the molten mass caused by the welding. Independent claim describes connection device with at least one adapter (1) which has means for controlling the build up area of the molten mass caused by the friction welding. The adaptor has an inner pipe (3) whose outside surface is provided at least in some areas with anti-friction means.
