  • Connecting element for pipes and method for welding a connecting element onto the end of a pipe
    Patent number: 7093864
    Abstract: The invention relates to a connecting element for welding onto a circular front face of a pipe, said element having an annular region, (friction region), that can be friction welded to said front face. The connecting element can be welded onto the end of a pipe with a substantially circular front face in a particularly simple, rapid and cost-effective manner. Said element, together with additional components, e.g. a coupling nut and a threaded sleeve enables a tight connection of the pipe to other components, even under extreme pressure and temperature fluctuations.
