Abstract
A clamp system is provided for clamping one tubular to another, such as control lines to a marine choke and kill riser line. The riser clamp comprises a saddle and U-bolt arrangement. The upper surface of the saddle defines a track configured to receive a shoe attached to either the control line clamp or an extension leg attached to the control line clamp. The control line clamp comprises an upper clamp half, a lower clamp half, a hinge pin connecting the halves, a fastener latching the halves, and a support leg having a shoe for receipt by either the saddle structure or the extension leg. The control line clamp preferably contains an elastomeric liner. The elastomeric liner is preferably provided in two halves. The inner surface of each liner half preferably is provided with a non-skid layer to more firmly position the control line.
Claims16
An elastomeric liner half for a hinged hose clamp or cable clamp, said liner half being formed from an elastomeric material and defining an inside wall defining at least one semicylindrical trough having a longitudinal axis, a first end, and a second end, said semicylindrical trough being for closely receiving a hose or cable to be clamped, and an outside wall to be closely received by an inside surface of a clamp half, said liner half having a first flange extending away from the longitudinal axis at the first end and a second flange extending away from the longitudinal axis at the second end for extending around a first end surface and a second end surface of a clamp half, said elastomeric liner half further having a first lip element positioned on the periphery of the first flange and extending over the outside wall and a second lip element positioned on the periphery of the second flange and extending over the outside wall so that the liner element can be snapped onto the clamp half.
A clamp for a tubular hose or cable, said clamp comprising
- an upper clamp half having a downwardly facing parting line face;
- a lower clamp half having an upwardly facing parting line face, said lower clamp half being positioned in a face to face relationship with the upper clamp half so that the parting line faces are side by side;
- a hinge pin pivotally connecting the clamp halves along a hinge edge,
- a fastener connecting the clamp halves along a latch edge;
- a support leg extending from the lower clamp half, said support leg having an upper end attached to the lower clamp half and a lower end;
- and
- a shoe positioned on the lower end of the support leg,
- wherein the clamp halves, when positioned in a face to face relationship, form a clamp assembly which defines at least one passage therethrough for clamping a cylindrical object, wherein said passage has a longitudinal axis and wherein the clamp assembly parts along a parting plane which encompasses the longitudinal axis, and wherein the support leg has a longitudinal axis which extends normally to the parting plane,
- said clamp further comprising an elastomeric liner which lines each of the passages which extend though the clamp assembly for clamping a cylindrical object
- said elastomeric liner further defining at least one semicylindrical trough for receiving the cylindrical object to be clamped and a layer of an anti-skid material positioned in each semicylindrical trough.
A clamp for a tubular hose or cable, said clamp comprising
- an upper clamp half having a downwardly facing parting line face;
- a lower clamp half having an upwardly facing parting line face, said lower clamp half being positioned in a face to face relationship with the upper clamp half so that the parting line faces are side by side;
- a hinge pin pivotally connecting the clamp halves along a hinge edge,
- a fastener connecting the clamp halves along a latch edge;
- a support leg extending from the lower clamp half, said support leg having an upper end attached to the lower clamp half and a lower end;
- and
- a shoe positioned on the lower end of the support leg,
- wherein the clamp halves, when positioned in a face to face relationship, form a clamp assembly which defines at least one passage therethrough for clamping a cylindrical object, wherein said passage has a longitudinal axis and wherein the clamp assembly parts along a parting plane which encompasses the longitudinal axis, and wherein the support leg has a longitudinal axis which extends normally to the parting plane,
- said clamp further comprising an elastomeric liner which lines each of the passages which extend though the clamp assembly for clamping a cylindrical object
- said elastomeric liner further defining at least one semicylindrical trough for receiving the cylindrical object to be clamped and a layer of an anti-skid material positioned in each semi-cylindrical trough;
- wherein the clamp assembly defines a pair of passages extending therethrough in side-by-side relationship, said clamp further comprising a flange positioned on the support leg between the upper end and the lower end of the support leg which is of the same shape as the shoe.
Apparatus comprising
- an extension leg having a first end and a second end and a longitudinal axis extending between the first end and the second end, a shoe positioned on the first end of the leg, and a track positioned on the second end of the extension leg configured to receive the shoe,
- a clamp for a tubular hose or cable, said clamp comprising
- an upper clamp half having a downwardly facing parting line face,
- a lower clamp half having upwardly an upwardly facing parting line face, said lower clamp half being positioned in a face to face relationship with the upper clamp half so that the parting line faces are side by side,
- a hinge pin pivotally connecting the clamp halves along a hinge edge,
- a fastener connecting the clamp halves along a latch edge,
- a support leg extending from the lower clamp half, said support leg having an upper end attached to the lower clamp half and a lower end, and
- a shoe positioned on the lower end of the support leg,
- wherein the shoe positioned on the lower end of the support leg is received by the track positioned on the second end of the extension leg, and
- a clamp for a tubular member comprising
- a saddle structure having a first end and a second end, an upper surface and a lower surface, wherein the lower surface defines a trough extending from the first end to the second end for mounting the saddle structure to a tubular member, and at least one pair of parallel apertures positioned one on each side of the trough for receiving a first U-bolt for fastening the saddle structure to the tubular member, and
- a first U-bolt having a first end and a second end which are received by the apertures, said U-bolt extending over the trough,
- wherein the upper surface of the saddle structure defines a track configured to receive a shoe,
- wherein the shoe positioned on the first end of the extension leg is received in the track on the upper surface of the saddle structure.
