It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based. The inventive aspects can relate to individual features and to combinations of features. One inventive aspect of the disclosure relates to conduit clamps having structures adapted for providing a more uniform clamping force around the circumference of flanged conduits being clamped together as compared to prior art style V-band clamps.Īnother inventive aspect of the disclosure relates to conduit clamps adapted to conform to variations in flange shape provide improved sealing performance.Ī further inventive aspect of the disclosure relates to conduit clamps and to clamping systems having enhanced sealing capabilities.Ī variety of additional inventive aspects will be set forth in the description that follows. Reasons for such failures include non-uniform clamping forces about the circumferences of the flanges, inadequate clamping forces, and the inability of clamps to effectively conform to irregularities in the shapes of the flanges. However, for a number of reasons, clamps of the type described above often fail to provide an adequate seal between two flanged conduits. Ideally, V-band clamps of the type described above provide an effective seal between the flange end faces of two conduits being clamped together. By tightening the bolt 32, the clamp 20 draws the flanges 44, 46 together to provide a secure connection between the conduits 40, 42. To clamp the conduits 40, 42 together, the flanges 44, 46 are placed in an abutting end-to-end relationship to form a joint, and the clamp 20 is then mounted over the joint with the abutting flanges 44, 46 inserted within the channels 38 of the channel members 36. The conduits 40, 42 respectively include flanges 44, 46. 2 shows the clamp 20 being used to clamp a first conduit 40 to a second conduit 42. The channels 38 provide a means for receiving the flanges of a pair of flanged conduits desired to be coupled together.įIG. 2) that opens inwardly toward the center of the clamp. Each of the channel members 36 defines a generally V-shaped channel 38 (see FIG. The clamp 20 also includes three channel members 36 secured to the inner side of the strap 22. The clamp 20 is tightened by threading the bolt 32 into the first trunion 28 such that the gap 34 closes. The bolt 32 passes through the clearance opening of the second trunion 30 and is threaded into the internally threaded opening of the first trunion 28. The first and second looped ends 24, 26 are fastened together by a bolt 32 that traverses a gap 34 between the looped ends 24, 26. The first trunion 28 defines an internally threaded opening, and the second trunion 30 defines a clearance opening. First and second trunions 28, 30 are respectively mounted within the first and second looped ends 24, 26.
The clamp 20 includes an outer strap 22 having first and second looped ends 24 and 26. 1 illustrates a prior art V-band clamp 20 for coupling flanged conduits. More particularly, the disclosure relates to clamps including channels having V-shaped cross-sections. The principles disclosed herein relate to clamps for coupling flanged conduits such as pipes or ducts. 7, 2005, which applications are hereby incorporated by reference in their entirety.
