摘要： A press fitting for a pipe connection is provided. The press fitting comprises a fitting body for connecting the press fitting to a pipe, a substantially cylindrical pressing sleeve fixed to the fitting body and having a pressing area, and a stop ring fixed to the pressing sleeve and limiting the pressing area in an axial direction of the press sleeve. The stop ring has a substantially cylindrical inner contour with protruding first regions and second regions receding from the first regions. The first areas of the first stop ring encompass an outer contour of the pressing sleeve in a clamping manner. The second areas of the stop ring are spaced from the outer contour of the pressing sleeve.

摘要： A method for expanding an end of a pipe made of plastics having shape memory with the aid of an expander tool having a tool head having an expansion member arranged to be insertable inside the end of the pipe. The method includes steps of measuring the temperature of the pipe to be expanded, adjusting at least one of the expansion control parameters of the tool head on the basis the measured temperature of the pipe, and expanding the end of the pipe utilizing the adjusted expansion control parameter of the tool head. The expander tool includes a temperature sensor for measuring temperature of the pipe to be expanded and/or ambient temperature, and an electronic control unit for adjusting at least one of the expansion control parameters of the tool head on the basis the measured temperature value.
