摘要： 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.

摘要： A pipe coupling (11) comprises a tubular casing (12) and a sealing gasket (13), which fit over the ends of the pipes to be coupled. The casing (12) is formed from a strip of rolled steel into a cylindrical shape, with a longitudinal gap (14). The free ends of the strip, which forms the casing, are bent outwardly to form radially projecting flange (15) along opposite edges of the longitudinal gap (14). The outer ends of the flanges (15) are bent back at right angles to form stiffening flanges (16) along the longitudinal outer edges of the flanges (15). A bridging member (18) fits inside the casing so as to span the longitudinal gap. Tensioning screw bolts (25) pass through reinforcing plate's (20) and the flange (15). A hexagonal nut (34) is threaded onto the end of each screw bolt. The nuts fit into the channel but are prevented from turning. The heads (35) of the bolts have a hexagonal recess to take an Allen key so that they can be tightened to clamp the coupling around the pipe ends.

摘要： An anchoring device for a pipe coupling including an annular channel of generally U-shaped cross-section. The channel has a web portion with flanges and projecting radially inwardly. A frusto-conical gripping ring is located in the channel with its outer edge inside the web portion adjacent one of the flanges and its inner edge adjacent the other flange and projecting inwardly beyond this latter flange. The annular channel forms an incomplete ring and is compressible circumferentially. The anchoring device is fitted inside a clamping device, which fits around a pipe coupling. The clamping device has a tensioning for tightening the clamping device around the pipe, compressing the annular channel and causing the inner edge of the frusto-conical gripping ring to engage the outer surface of the pipe and thus grip the pipe.

摘要： A pipe coupling for coupling together two pipes in a fluid-tight manner includes a tubular casing, a tubular sealing gasket located within the casing, and screws for tensioning the casing around the gasket. The casing includes an inner tubular casing and an outer tubular casing, both of metal. A layer of fire-resistant thermally-insulating material is disposed between the inner and outer casings to form a fire shield.

摘要： A pipe clamp 10 for repairing an underwater pipe. The pipe clamp 10 comprises a plurality of part-cylindrical portions 12,14,16 hinged together along a hinge axis or axes 27 along adjacent longitudinal edges 17,18. Two or the longitudinal edges 20,21 of the part-cylindrical portions are free. The part-cylindrical portions 12,14,16 are movable about the hinge axis or axes 27 towards and away from one another between an open position in which the free longitudinal edges 20,21 are spaced apart and the clamp 10 can be placed around a pipe and a closed position in which, in use, the free longitudinal edges 20,21 of the part-cylindrical portions 12,14,16 are brought together around the pipe. Fastening means are provided for holding the free edges 20,21 of the part-cylindrical portions 12,14,16 together, such that, in use, the clamp 10 is held to the pipe.

摘要： A pipe coupling 1 for connecting together two pipes in a fluid-tight manner comprising an outer tubular casing 10, an inner tubular casing 20 and a tubular sealing sleeve 30. The sealing sleeve 30 has two sets of inwardly projecting ribs 32, which in use, are pressed into sealing engagement with the respective ends of the pipes. The inner and outer casings are longitudinally split and tensioning screws 17 on the outer casing can be tightened to tighten the outer casing around the inner casing and the sealing sleeve. Frusto-conical gripping rings 40 grip the pipes by engaging radial abutment surfaces facing away from the pipe ends and positioned close to the ends of said pipes in order to secure the pipes against axial displacement.
