Abstract
A band type clamp for securing together first and second pipe sections each having outwardly projecting flanges with opposing flange faces that extend about the circumference thereof is described. The band type clamp includes a conforming material disposed between the band type clamp and the outwardly projecting flanges and is configured to engage the outwardly projecting flanges and to exert an inwardly directed radial force thereon when the band type clamp is tightened from a first un-tightened position to a second tightened position and to radially pilot the outer surfaces and the first and second pipe sections relative to each other and the corresponding centerlines thereof.
Claims20
A V-band type clamp for axially securing together, and radially positioning, first and second pipe sections relative to corresponding centerlines, the pipe sections each having outwardly projecting flanges with opposing flange faces that extend about the circumference thereof, comprising:
- an outer strap having a first end and a second end;
- a trunion joint in communication with the first end and the second end and configured to connect the first and second ends into a circumferentially extending assembly having a first un-tightened position and a second tightened position;
- an inner V-band in communication with the outer strap and extending substantially from the first end to the second end and comprising:
- an internal, circumferentially extending wall extending along the strap;
- frusto-conical side walls extending from the circumferentially extending wall and configured to engage remote faces of the outwardly projecting flanges and to exert opposed axial forces on the outwardly projecting flanges when the circumferentially extending assembly is in the second, tightened position;
- and
- a conforming material disposed on the internal, circumferentially extending wall and configured to engage outer surfaces of the outwardly projecting flanges and to exert an inwardly directed radial force thereon when the circumferentially extending assembly is in the second tightened position and to radially pilot the outer surfaces and the first and second pipe sections relative to each other and the corresponding centerlines thereof.
A V-band type clamp for securing together first and second pipe sections each having outwardly projecting flanges with opposing flange faces that extend about the circumference thereof, comprising:
- a conforming material disposed between the V-band type clamp and the outwardly projecting flanges and configured to engage the outwardly projecting flanges and to exert an inwardly directed radial force thereon when the V-band type clamp is moved between a first un-tightened position and a second tightened position to radially pilot the outer surfaces and the first and second pipe sections relative to each other and the corresponding centerlines thereof.
A band type clamp for securing together first and second pipe sections each having outwardly projecting flanges with opposing flange faces that extend about the circumference thereof by applying opposed axial forces thereon, comprising:
- a conforming material disposed between the band type clamp and the outwardly projecting flanges and configured to engage the outwardly projecting flanges and to exert an inwardly directed radial force thereon when the band type clamp is tightened and to radially pilot the outer surfaces and the first and second pipe sections relative to each other and the corresponding centerlines thereof.
