摘要： A mounting group for a press fitting is provided. The mounting group includes cylindrical pressing sleeve with a pressing area and a stop ring fixed to a first axial end of the pressing sleeve and limiting the pressing area in an axial direction of the pressing sleeve. The stop ring has a first inner contour on a side opposite the pressing area and as a first circular segment and a second circular segment, which extends over a smaller part of the first inner contour than the first circular segment. The stop ring has a constant cross-section in the region of the first circular segment and an element arranged in the region of the second circular segment which projects inwardly beyond the constant cross-section of the first circular segment and causes a tilting of an axis of symmetry of the pressing sleeve.

摘要： A tool device for expanding the end of a tube (T) includes an expansion sleeve element made of elastomeric material, the expansion sleeve element being arranged concentrically around a pull rod. A calibration sleeve is arranged concentrically around the expansion sleeve element. The inner die surface of the calibration sleeve comprises a mouth portion which has a fourth diameter (d4) which corresponds with a play to the outer diameter of the tube (T), at least one expansion die portion having a fifth diameter (d5, d6) which is larger than the fourth diameter (d4), and a shoulder between the mouth portion and the expansion die portion. The shoulder keeps the end of the tube (T), while being expanded, stationary in place inside the calibration sleeve. The calibration sleeve comprises mutually openable and closable calibration sleeve parts to enable closing of the calibration sleeve to a closed position (III) for the expanding operation of the end of the tube, and for opening of the calibration sleeve to an opened position (IV) for releasing the expanded end of the tube.

摘要： This invention relates to a polymeric pipe, and more particularly a polymeric pipe where the pipe comprises a crosslinked polyolefin formed from extruded polyolefin comprising a photoinitiator. More particularly, this invention relates to the manufacturing of plastic pipes and tubing by utilizing co-rotating twin screw extrusion combined with photo-induced cross-linking, of thermoplastic polymers such as polyethylene, to produce PEX pipes and tubing.

摘要： A press fitting for a pipe connection is provided. The press fitting includes a fitting body for connecting the press fitting to a pipe, a press sleeve fixed to the fitting body and having a substantially cylindrical pressing portion and at least one projecting element which delimits the substantially cylindrical pressing portion in the axial direction, and a tubular banderole which surrounds the substantially cylindrical pressing region of the pressing sleeve, wherein the tubular banderole is arranged rotatably relative to a surface of the pressing sleeve, is held in the cylindrical pressing region by the at least one projecting element and is at least partially destroyed when the pressing sleeve is pressed with a pressing tool.

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 mold assembly (1) for injection molding of a plastic pipe fitting (2, 3). The pipe fitting comprises an elbow-shaped or a tee-shaped internal flow channel (4). At least one of the first core member (14) and the second core member (15) of the core package (12, 13) comprises a built-in cooling arrangement (20) for cooling of the core package (12, 13), the cooling arrangement (20) extending longitudinally inside said core member over a substantial length of said core member. The pipe fitting (2, 3) comprises an elbow-shaped or tee-shaped internal flow channel (4) comprising at least two channel parts (5, 6, 7) arranged at a first angle (α) in relation to each other, the channel parts (5, 6, 7) each having a circular cross-section and a smoothly radiused inner corner face (8) between each two channel parts being at said first angle in relation to each other, the at least one of the channel parts having an inner diameter D, a length L from central corner point to the end of the channel part, the inner corner face having a rounding radius R. The ratio (D/R) of the inner diameter D and the rounding radius R is in the range 2 to 5, and the ratio (L/D) of the length L and inner diameter D is in the range 8 to 3.
