  • Publication number: 20050248152
    Abstract: A pressed-connection arrangement (1) has a connection piece (2) made of a cold-workable material, which is constructed on a fitting or a valve and into which a pipe end (3) can be pushed. The connection piece (2) has a ring-shaped receiving device (5) in which a metallic cutting ring (10) and a sealing ring (8) are held. Between the sealing ring (8) and the cutting ring (10), a separating ring (9) is provided, by means of which separating ring (9), the cutting ring (10) is held at a distance from the sealing ring (8). As a result, only a single ring-shaped receiving device has to be shaped out on the connection piece (2), in which ring-shaped receiving device the sealing ring (8), the separating ring (9) and the cutting ring (10) are then held.

  • Publication number: 20040003645
    Abstract: The disclosed process permits the production of special steel press fittings practically in a single work step, which comprises two process steps, which can be performed simultaneously, or also one after the other. The cut to size blank is widened in a die and is upset in order to form the desired pipe connection areas. The process has been shown to be dependable for special steel press fittings. Other pressure-resistant and tough metals can also be employed. The process is particularly suitable in connection with a following roller-burnishing step or grinding step for producing press fittings from welded special steel pipes.

  • Patent number: 6581983
    Abstract: A fitting or a mounting part, particularly for the connection with a tube-shaped component, comprises an end section, which can be pressed together for establishing a connection. At the end section, a ring-shaped elevation is arranged in which a sealing ring is disposed. According to the invention, a bulge is provided on the elevation. By means of the bulge, a space is formed between the sealing ring and the wall of the end section, such that a fluid can flow between the tube-shaped components. Only by pressing together this leaky point, will a sealed-off connection arrangement be established.
