A pipe clamp for connecting pipe ends together to form a gas tight seal. The clamp includes an open band, tightening mechanism, split sealing sleeve, and inner gasket. The band extends circumferentially from a first end to a second end and has a pair of axial ends. The band includes a radially protruding rib located inwardly of the axial ends, and this rib extends at least part way between the first and second ends. The split sleeve is disposed within the band and is located at least within the rib. The gasket is disposed radially within the sleeve such that it is located at least partially within the rib. Each of the pipe ends can have a protruding bead and the clamp can be placed over the two pipe ends during assembly such that the beads engage the gasket within the center rib region of the band.

The invention claimed is: 1. A pipe clamp for connecting two tubular bodies, comprising: a band extending circumferentially and continuously from a first end to a second end and having a pair of axial ends, said band including a radially protruding rib located inwardly of said axial ends and extending continuously at least part way between said first and second ends, wherein said first and second ends of said band comprise radially extending flanges; a tightening mechanism connected to said flanges to draw said first and second ends toward and away from each other for tightening and loosening of said band; a split sleeve disposed within said band and located at least within said rib such that, when tightened, said band compresses said sleeve via direct contact between a radially inward surface of said rib and an outer surface of said sleeve, said split sleeve extending circumferentially from a first mating end to a second mating end; and a gasket disposed radially within said sleeve such that said gasket is located at least partially within said rib. 2. A pipe clamp as defined in claim 1, wherein said flanges each have an aperture aligned with the aperture of the other flange, and wherein said tightening mechanism includes a single nut and bolt fastener and a backing plate, said bolt extends through the aligned apertures of the two flanges, through the backing plate, and into its corresponding nut such that tightening of the nut onto the bolt draws the flanges together via the backing plate. 3. A pipe clamp as defined in claim 2, wherein said tightening mechanism further includes a reaction member located between said flanges. 4. A pipe clamp as defined in claim 2, wherein said bolt includes a head and a shank, said bolt head and said backing plate extending an axial distance sufficient to disperse a force from said tightening mechanism across each of said two flanges. 5. A pipe clamp as defined in claim 1, wherein said flanges are formed from unitary end portions of said band, each of said end portions being folded back over itself to provide said flange with an inner and out leg. 6. A pipe clamp as defined in claim 1, wherein said sleeve includes first and second mating ends having a circumferential separation such that said mating ends nearly come into engagement when said tightening mechanism is fully tightened, but do not substantially touch each other. 7. A pipe clamp as defined in claim 6, wherein said gasket includes first and second mating ends having a circumferential separation such that said mating ends barely come into engagement when said tightening mechanism is fully tightened, but do not substantially overlap each other. 8. A pipe clamp as defined in claim 1, wherein said rib, said sleeve and said gasket each have an axial width that it is generally the same. 9. A pipe clamp as defined in claim 1, wherein said flanges each have a pair of apertures aligned with the apertures of the other flange, and wherein said tightening mechanism includes a pair of nut and bolt fasteners and a backing plate, said bolts each extending through a pair of the aligned apertures of the two flanges, through the backing plate, and into their corresponding nut such that tightening of the nut onto the bolt draws the flanges together via the backing plate, and wherein said backing plate is notched with the protruding rib of the band being located at least partially within said notch. 10. A pipe clamp as defined in claim 9, wherein said tightening mechanism further includes a reaction member located between said flanges, wherein said reaction member is notched with the split sleeve being located at least partially within said reaction member notch. 11. A pipe clamp as defined in claim 1, wherein said flanges are formed from unitary end portions of said band, each of said end portions being folded back over itself to provide said flange with an inner and out leg, and wherein said protruding rib of said band extends into at least a lower portion of said inner and outer leg of each flange. 12. A pipe clamp as defined in claim 1, wherein said gasket comprises a solid ring of graphite material. 13. A pipe clamp as defined in claim 12, wherein said gasket has a density in the range of 70 to 130 lbs/cf. 14. A pipe clamp for connecting two tubular bodies, comprising: a band extending circumferentially from a first end to a second end and having a pair of axial ends, said band including a radially protruding rib located inwardly of said axial ends and extending at least part way between said first and second ends, said first and second ends having radially extending flanges each having a pair of apertures aligned with the apertures of the other flange; a tightening mechanism connected to said band to draw said first and second ends toward and away from each other for tightening and loosening of said band, said tightening mechanism including a pair of nut and bolt fasteners and a backing plate, said bolts each extending through a pair of the aligned apertures of the two flanges, through the backing plate, and into their corresponding nut such that tightening of the nut onto the bolt draws the flanges together via the backing plate, and wherein said backing plate is notched with the protruding rib of the band being located at least partially within said notch; a split sleeve disposed within said band and located at least within said rib, said split sleeve extending circumferentially from a first mating end to a second mating end; and a gasket disposed radially within said sleeve such that said gasket is located at least partially within said rib. 15. A pipe clamp as defined in claim 14, wherein said tightening mechanism further includes a reaction member located between said flanges, wherein said reaction member is notched with the split sleeve being located at least partially within said reaction member notch. 16. A pipe clamp for connecting two tubular bodies, comprising: a band extending circumferentially from a first end to a second end and having a pair of axial ends, said band including a radially protruding rib located inwardly of said axial ends and extending at least part way between said first and second ends, said first and second ends having radially extending flanges formed from unitary end portions of said band, each of said end portions being folded back over itself to provide said flange with an inner and outer leg, said rib extending into at least a lower portion of said inner and outer leg of each flange; a tightening mechanism connected to said band to draw said first and second ends toward and away from each other for tightening and loosening of said band; a split sleeve disposed within said band and located at least within said rib, said split sleeve extending circumferentially from a first mating end to a second mating end; and a gasket disposed radially within said sleeve such that said gasket is located at least partially within said rib.
