  • Patent number: 7425023
    Abstract: A profiled clamp with at least one profiled segment which extend successively in the circumferential direction of the clamp and are clamped by means of at least one clamping device. The profiled segments have a profile which in cross-section is essentially inversely trough-shaped or cup-shaped. When the clamp is clamped, flanges which are provided at the ends of two pipes to be connected by the clamp are pressed toward each other between diverging side walls of the profiled segments. Gaps with a bottom each are provided between adjacent profiled segments. In each gap is provided a resilient metal strip at a distance from the bottom of the gap which is greater than the thickness of the bottom of the profiled segments, wherein the metal strip extends transversely of the plane of the clamp, and wherein the metal strip is mounted through lateral arms of the metal strip at the bottom of the gap.

  • Patent number: 7393020
    Abstract: In a pipe connection, a first pipe has a first flange of sheet metal provided with a first wall connected circumferentially to the first pipe. A second pipe has an end section shaped as a second flange. A clamp engages across the first and second flanges and has conical sidewalls forcing the first and second flanges axially against one another when tightening the clamp. The first flange delimits together with the first pipe an annular chamber that is coaxial to the longitudinal pipe axis. The first flange has a second wall that is glidingly supported on a free end of the first pipe. A sheet metal sealing ring is positioned between the first and second flanges. It has an edge section that is bent back onto a remaining sealing ring section that has a corrugation projecting past the bent edge section in an untightened state of the clamp.
