  • Patent number: 8430432
    Abstract: A pipe coupling with an anchoring arrangement for locking the pipes together axially. The anchoring arrangement comprises a tubular casing, a frusto-conical gripping ring with inwardly projecting gripping teeth and tensioning bolts for tightening the casing about the frusto-conical gripping ring. The frusto-conical gripping ring is formed of a plurality of arcuate segments which overlap to form a complete ring. By forming the gripping ring of segments, the gripping ring is able to adapt to pipes that are not truly circular in cross section and a better grip on the pipe may be achieved than with a single-piece gripping ring.

  • Patent number: 8292331
    Abstract: A sleeve-shaped anchoring element for pipe couplings sealing pipes, with an essentially cylindrical housing and a sealing element of rubber-elastic material that is arranged in the housing. The anchoring element is arranged in the housing and has individual longitudinal supports connected to each other by means of deformable webs and having a C-shaped longitudinal section. Ends of the longitudinal supports are configured as limbs angled radially inwards. Free ends of the limbs can be brought into engagement with at least one of the pipes when the pipe coupling is clamped. Only one single web is provided between two adjacent longitudinal supports, and the two webs of a longitudinal support are arranged offset with respect to each other in the axial direction for connection to the adjacent longitudinal supports.

  • Publication number: 20120217743
    Abstract: A pipe coupling assembly includes a pair of casing members each having a first end including a first continuous exterior surface edge defined by a first radius, and a second end including a second continuous exterior surface edge defined by a second radius. The first radius is smaller than the second radius so that a tapering, continuous, exterior surface extends therebetween. A gasket is to be positioned adjacent first and second pipe sections, and within the pair of casing members. A sleeve has a tapering interior surface to be positioned over the tapering, continuous, exterior surfaces of the pair of casing members. The second end of at least one of the pair of casing members includes a sleeve locking tab extending outwards from the second continuous, exterior surface edge so that the sleeve is lockable in position surrounding the pair of casing members by engagement with the sleeve locking tab.

  • Patent number: 8151828
    Abstract: A pipe-clamping tool (100) comprises a tool body (102) and first and second tool jaws (104, 106). The tool further comprises a bar (110) in threaded engagement with a portion of the tool body. One end of the bar engages with a boss (108) on a side of the first tool jaw opposite the curved surface thereof. The tool jaws may be closed and opened by rotation of a handwheel (112). The first tool jaw has projections (111A, 111B) which engage respective grooves (101A, 101B) on opposite sides of the tool body; together with the bar and boss, these inhibit rotation of the first tool jaw with respect to the tool body. The pipe-clamping tool may be used to stop a leak in a pipe by applying a layer of deformable material around the pipe and clamping it in place using the tool. The tool enables a substantially complete (360°) azimuthal seal around a pipe with only a single operation on the tool (i.e. rotation of the handwheel to close the tool jaws). The tool jaws remain mutually aligned as they are opened and closed.

  • Patent number: 8128126
    Abstract: A coupling device formed of two identical sides is disclosed. Each of the two sides have a snap fitting mechanism which engage each other to releasably secure the sides together thereby forming the coupling device. The coupling device as formed has a main body communicating with at least two openings. Each opening is sized to engage an end of a corresponding conduit. Generally, the conduits are corrugated such that the openings engage one corrugation to form the friction fit. The openings may be conically shaped with pre-scored cut lines that can be cut at different diameters to engage conduits of different diameters. The openings of the coupling device have pre-score cut lines that may be cut in order to create the friction fit with corrugated conduits having different diameters.
