A pipe clamp, comprising: a band extending circumferentially from a first circumferential end to a second circumferential end, and extending axially from a first axial end to a second axial end, said band having an inner surface defining a first channel segment located inwardly of said first and second axial ends (36, 38) and extending at least part way between said first and second circumferential ends (232, 234); a tightening mechanism connected to said band, said tightening mechanism including at least one fastener to bring said first and second circumferential ends (232, 234) toward each other to tighten said band, and including a reaction block with a radially-facing inward surface; a bridge attached to said reaction block at said radially-facing inward surface, said bridge circumferentially spanning a break in the circumferential extent of said band at said tightening mechanism wherein, upon tightening of said tightening mechanism, said bridge keeps with said reaction block when said first and second circumferential ends (232, 234) of said band come closer together and closer to said reaction block; and a first gasket seated at least partially within said first channel segment; characterized in that: said bridge has a first cutout located in a first circumferential end thereof and has a second cutout located in a second circumferential end thereof, the first and second cutouts (303, 305) having substantially the same axial extent as said first channel segment; said band has a first and second flange (244, 246) respectively extending from said first and second circumferential ends (232, 234) of said band, said first and second flanges (244, 246) opposing each other; said tightening mechanism is connected to said first and second flanges (244, 246); said first gasket has an open loop structure with a first circumferential end and a second circumferential end, said first circumferential end located at said first flange and confronting said first flange, and said second circumferential end located at said second flange and confronting said second flange; and the pipe clamp further comprises a second gasket located at said bridge and having a first circumferential end at least partially overlapping said first cutout and having a second circumferential end at least partially overlapping said second cutout. a band extending circumferentially from a first circumferential end to a second circumferential end, and extending axially from a first axial end to a second axial end, said band having an inner surface defining a first channel segment located inwardly of said first and second axial ends (36, 38) and extending at least part way between said first and second circumferential ends (232, 234); a tightening mechanism connected to said band, said tightening mechanism including at least one fastener to bring said first and second circumferential ends (232, 234) toward each other to tighten said band, and including a reaction block with a radially-facing inward surface; a bridge attached to said reaction block at said radially-facing inward surface, said bridge circumferentially spanning a break in the circumferential extent of said band at said tightening mechanism wherein, upon tightening of said tightening mechanism, said bridge keeps with said reaction block when said first and second circumferential ends (232, 234) of said band come closer together and closer to said reaction block; and a first gasket seated at least partially within said first channel segment; said bridge has a first cutout located in a first circumferential end thereof and has a second cutout located in a second circumferential end thereof, the first and second cutouts (303, 305) having substantially the same axial extent as said first channel segment; said band has a first and second flange (244, 246) respectively extending from said first and second circumferential ends (232, 234) of said band, said first and second flanges (244, 246) opposing each other; said tightening mechanism is connected to said first and second flanges (244, 246); said first gasket has an open loop structure with a first circumferential end and a second circumferential end, said first circumferential end located at said first flange and confronting said first flange, and said second circumferential end located at said second flange and confronting said second flange; and the pipe clamp further comprises a second gasket located at said bridge and having a first circumferential end at least partially overlapping said first cutout and having a second circumferential end at least partially overlapping said second cutout.
