The Casing Holder is an external gripping device which holds strings of casing on the OD using a conventional “slip” action. It is generally used to hold the casing string in the borehole while additional lengths of casing are added to the string.
Casing Holder features:
- Available with mechanical, air or hydraulic slip actuation.
- Inclined wedge holding system, no shoulder required.
- Thirty-five ton holding capacity.
- Can be installed above or below drilling table.
- Comes with one set of slips.
Height is to top of linkage. Handle is removable and can be installed at either end of holder. Pneumatic/Hydraulic Casing Holders and Removable Side Plates are available on any model. Model Size is dictated by the maximum casing size that will fit into a particular Holder Frame. Note that slips designed to fit a small frame size such as 4 – 8 are less expensive than the same size slips to fit Model 4 – 26. Some drillers prefer to have several different sized models particularly if they have multiple rigs.
