20080272595 | Mechanical Pipe Coupling Having Spacers - A mechanical pipe coupling is disclosed having an arcuate band with first and second ends in facing relation. A hinge is positioned between the first and second ends allowing the ends to move relatively to one another. Connection members are mounted on the ends, and a spacer is positioned between the ends to maintain the ends in spaced apart relation sufficient to allow end portions of a pipe to be inserted between arcuate surfaces which extend radially inwardly from the band. The spacer is configured to allow for tightening of the connection members to draw the ends together and permit the arcuate surfaces to engage the outer surfaces of the pipe elements and form a joint. | 11-06-2008 |
20080290652 | Mechanical Pipe Coupling Having Spacers - A preassembled mechanical pipe coupling having spacers is disclosed. The coupling has a plurality of interconnectable segments that straddle the ends of pipe elements to be joined. The segments have arcuate surfaces that engage outer surfaces of the pipe elements. Spacers, positioned between the segments, maintain them in spaced apart relation sufficient to allow the pipe elements to be inserted between the segments. The segments have adjustably tightenable connection members for connecting the segments and drawing them to one another. When the connection members are tightened and the effect of the spacers is overcome, the arcuate surfaces are brought into engagement with the outer surfaces of the pipe elements. | 11-27-2008 |
20090206598 | Method of Securing Pipe Elements End to End - A method of joining pipe elements in end to end relation using mechanical pipe couplings. The couplings have a plurality of segments attached end to end surrounding a central space. The segments have arcuate surfaces adapted to interface with the outer surfaces of the pipe elements. The method includes inserting end portions of the pipe elements into the central space and then drawing the coupling segments toward one another so as to engage the arcuate surfaces of the segments with the outer surfaces of the pipe elements. | 08-20-2009 |
20090243291 | Flanged Mechanical Pipe Coupling Having Spacers - A mechanical pipe coupling having segments joined end to end by connection members has arcuate surfaces and flanges in spaced relation to the arcuate surfaces on each segment. The coupling is positionable between a first pipe element having a cylindrical outer surface and a second pipe element having an end flange to couple the pipe elements to one another. The arcuate surfaces engage the outer surface of the first pipe element; the flanges engage the end flange on the second pipe element. One or more spacers support the coupling segments in spaced relation to one another to permit insertion of the first pipe element between the segments. The spacers are deformable upon tightening of the connection members to permit the arcuate surfaces to engage the pipe element and the flanges to align with the end flange. | 10-01-2009 |
20100320756 | Deformable Mechanical Pipe Coupling with Shoulder Pipe Elements - A mechanical pipe coupling formed of segments attached end to end surrounding a central space is used to connect pipe elements having a raised circumferential shoulder in end to end relationship. The segments have arcuate surfaces and arcuate landings which subtend an angle less than 180° and which have a radius of curvature greater than the radius of curvature of outer surfaces of the pipe elements on the raised circumferential shoulder. The segments are maintained in spaced relation allowing the pipe elements to be inserted into the central space without disassembling the pipe coupling. Connection members attaching the segments to one another are tightened to engage the arcuate surfaces or the arcuate landings with outer surfaces of the pipe elements to effect the connection. | 12-23-2010 |
20130200609 | Fitting for Joining Pipe Elements - A fitting for joining pipe elements together includes housing portions held preassembled in spaced apart relation to permit pipe elements to be inserted without disassembly of the fitting. Elbow and tee fittings include sealing elements which support the housing portions in spaced relation. Angled surfaces on each housing portion interact with one another to rotate the housing portions in opposite directions to form a rigid joint between the fitting and the pipe elements. | 08-08-2013 |
20140246852 | Combination Sealing Member and Pipe Couplings - A sealing member is disclosed having an outer surface that supports segments of a pipe coupling for joining pipe elements in end to end relation. The segments are supported in spaced relation to permit the pipe elements to be inserted into the coupling without disassembly. The sealing member is a flexible ring that has conical lips around its inner circumference to engage and guide the pipe elements into the coupling. A tongue extends radially inwardly between the lips, the tongue having conical shoulders which engage and guide the pipe ends. The tongue locates the coupling segments relatively to the pipe elements. | 09-04-2014 |
20140346769 | Fitting For Joining Pipe Elements - A fitting for joining pipe elements together includes housing portions held preassembled in spaced apart relation to permit pipe elements to be inserted without disassembly of the fitting. Elbow and tee fittings include sealing elements which support the housing portions in spaced relation. Angled surfaces on each housing portion interact with one another to rotate the housing portions in opposite directions to form a rigid joint between the fitting and the pipe elements. | 11-27-2014 |
