Abstract

An aspect of the invention is provides a clamping shell for placement about an elongate pipe for accommodating a chain vise thereover, the clamping shell having: a pair of elongate generally arcuate half-shells, each half shell having an internal portion for engagement with the pipe, the internal portion including a non-uniform surface for frictional engagement with the pipe; and at least one of the half-shells of the pair including a pocket formed on an external surface thereof for supporting the chain vise therein.

Claims (14)

1. A clamping shell for placement about an elongate pipe for accommodating a chain vise thereover, said clamping shell comprising:

a pair of elongate generally arcuate half-shells, each half shell having an internal portion for engagement with said pipe, said internal portion including a non-uniform surface including a scored pattern for frictional engagement with said pipe, said scored pattern allowing for gripping of the pipe without damage thereto;

at least one of said half-shells of said pair including a pocket formed on an external surface thereof for supporting said chain vise therein;

said external surface of said one half-shell including elongate stiffening ribs; and

wherein said stiffening ribs are elongate and longitudinally spaced and wherein said space between said ribs defines said pocket.

2. A clamping shell of claim 1 wherein said elongate stiffening ribs have a tapered height extending from the external surface of said one half shell.

3. A clamping shell of claim 2 wherein said stiffening ribs taper downward from a central space apart location.

4. A clamping shell of claim 3 wherein said spaced apart location defines said pocket.

5. A clamping shell for placement about an elongate pipe for accommodating a chain vise thereover, said clamping shell comprising:

a pair of elongate generally arcuate half-shells, each half shell having an internal portion for engagement with said pipe, said internal portion including a non-uniform surface including a scored pattern for frictional engagement with said pipe, said scored pattern allowing for gripping of the pipe without damage thereto;

at least one of said half-shells of said pair including a pocket formed on an external surface thereof for supporting said chain vise therein;

wherein said non-uniform internal surface of half-shells are defined by a depression pattern in said internal surface.

6. A clamping shell of claim 5 wherein said depression patterns is a cross-hatch.

7. A clamping shell of claim 6 wherein said cross-hatch pattern is a 60° cross-hatch pattern.
