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. |
