Abstract
A clamp assembly provides an attachment point for securely gripping pipe or other tubular goods including, without limitation, a section of coiled tubing. The clamp assembly beneficially includes a pad-eye member for attaching the clamp assembly (and any attached tubing) to a hook of a crane or other lifting mechanism. The clamp assembly also prevents partially unspooled coiled tubing from re-winding through a winding guide of a spool, thereby maintaining a distal outer end of the coiled tubing in an easily accessible location.
Claims14
A clamp assembly for gripping an external surface of pipe or other tubular goods comprising:
- a) a central pad-eye member having at least one aperture adapted to be connected to a lifting apparatus;
- b) a first half member pivotally attached to said central pad-eye member having a first substantially semi-cylindrical inner surface;
- c) a second half member pivotally attached to said central pad-eye member having a second substantially semi-cylindrical inner surface, wherein said first and second half members can be biased toward each other so that said first and second inner surfaces cooperate to form a substantially cylindrical bore;
- d) a plurality of gripping teeth disposed on said first and second inner surfaces.
A clamp assembly for gripping an external surface of pipe or other tubular goods comprising:
- a) a central pad-eye member having at least one aperture adapted to be connected to a lifting apparatus;
- b) a first half member pivotally attached to said central pad-eye member;
- c) a first die member removably attached to said first half member, wherein said first die member defines a first substantially semi-cylindrical inner surface;
- d) a second half member pivotally attached to said central pad-eye member;
- e) a second die member removably attached to said second half member, wherein said second die member defines a second substantially semi-cylindrical inner surface, and said first and second die members cooperate to form a substantially cylindrical bore when said first and second half members are joined together;
- and
- f) a plurality of gripping teeth disposed on said first and second inner surfaces.
A method for conducting operations on a well using continuous tubing on a spool comprising:
- a) attaching a clamp assembly to an external surface of said tubing, wherein said clamp assembly comprises:
- i) a central pad-eye member having at least one aperture adapted to be connected to a lifting apparatus;
- ii) a first half member pivotally attached to said central pad-eye member having a first substantially semi-cylindrical inner surface;
- iii) a second half member pivotally attached to said central pad-eye member having a second substantially semi-cylindrical inner surface, wherein said first and second half members can be biased toward each other so that said first and second inner surfaces cooperate to form a substantially cylindrical bore;
- iv) a plurality of gripping teeth disposed on said first and second inner surfaces;
- b) connecting said clamp assembly to a lifting apparatus;
- c) moving said tubing from said spool to an injector head using said lifting apparatus to support said tubing;
- d) disconnecting said clamp assembly from said lifting apparatus;
- and
- e) removing said clamp assembly from said tubing.
