  • Patent number: 8491017
    Abstract: An engagement section of a holder is engaged with a metal gasket, the gasket is received in a tubular section, and the tubular section is fitted in a step of a connection pipe. Another connection pipe is placed close to and facing the connection pipe that holds the gasket through the holder, and a center ring is installed surrounding the outer peripheries of the flanges. While a trapezoidal section having slopes which define both sides is inserted into a groove, center ring segments are closed to form a ring shape. A bolt which penetrates through a cutout of a segment is screwed into a threaded hole of the segment. The screwing of the bolt causes the amount of insertion of the trapezoidal section, which has slopes which define both sides, into the groove to be increased. As a result, the distance between flanges is reduced and the contact pressure of projections against both sides of the gasket is increased.

  • Patent number: 8454056
    Abstract: A clamp apparatus for holding together two abutting pipe ends, in which the pipe ends have radial flanges to facilitate the exerting of axial compressive forces on the pipe ends. The clamp includes a first strap structure and a fastening mechanism for providing circumferential compressive force on retainer segments configured to transfer the compressive force onto the flanges of the pipe ends. The clamp apparatus also includes a secondary strap structure for providing independent redundancy, relative to the primary strap, to supply back-up circumferential force onto the primary strap structure, should a failure occur in either of the fastening mechanism or the primary strap structure, to enable the clamp to maintain clamping force on the abutting pipe ends.

  • Patent number: 8439408
    Abstract: A pipe repair clamp includes a flexible strap having ends that are brought together when the clamp is closed. A thrust plate is secured near the first end of the flexible strap. A lug is secured to the thrust plate. A lug plate is secured near the second end of the strap. A threaded stud is secured to the lug plate and is used to tighten the clamp. A lug cover plate is secured to the lug and the thrust plate and receives the threaded stud. The lug cover plate includes a curved end portion covering at least a portion of the lug. A locking plate receives the threaded stud. The locking plate slides along a top surface of the lug and over the lug cover plate when the first and second ends of the strap are pulled toward each other when the clamp is tightened around a pipe.

  • Patent number: 8267438
    Abstract: A two-piece flange adapter including two identical flange parts. Each flange part has two ends, with each end having a planar mating surface disposed at each end of the channel disposed on an inner diameter surface of the flange part. A projection extends from one planar mating surface and is formed to continue the channel for a predetermined distance past the planar mating surface. The other end of the flange and channel define a groove having a depth that accepts the projection of a mating flange part to form a complete channel. A gasket having a cross-sectional area with an internal cavity is compressively disposed in a pocket defined by the channel and the mating pipes. The cross-sectional area of the gasket occupies less than 87% of the pocket and can also occupy approximately 82-84% of the pocket.

  • Patent number: RE45304
    Abstract: A coupling for securing pipe elements together in end-to-end relation has segments joined end-to-end by adjustable connection members. The segments surround a central space which receives the pipe elements. One or more gripping bodies are captured between the segments. The gripping bodies are arranged opposite to each other. The segments have angularly oriented reaction surfaces on the connection members. The gripping bodies have angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping bodies radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping bodies engage and retain the pipe elements.
