Keystone Energy offers a wide variety of different types of Slips for different oil and gas needs. 

Yet, in this blog, we will drill down into everything you need to know about our Drill Collar Slips.

What Are Drill Collar Slips and What Are They Used For?

Drill Collar Slips are devices used to grip and hold drill collars, as well as wash pipe, to the drill floor on an oil rig. The slips are constructed as a collection of metal wedges, hinged together to form a circular shape around the tubular. On the inside surface, the slips have replaceable steel teeth that grip the pipe.

The outsides of the slips are tapered and meets a similar taper on the drill floor. 

After the slips are placed around the tubular, it is lowered so that the teeth on the inside grip the pipe and the slips are pulled down. The wedges then holds the tubular by the compressive force.

After work is completed, the string is raised, thereby unlocking the gripping action. The slips are then lifted away.
