Get a grip! Using Slips

As their namesake suggests, slips are designed to help keep drill pipe from slipping down into the hole or to hold pipe in place. Small but mighty, these specially-designed gripping tools are carefully engineered to handle delicate and dangerous pipes in high-risk environments like drilling rigs.

Slips are wedge-shaped tools that wrap around the drill string. Inside, the slip is lined with small serrated teeth, known as inserts, designed to firmly grip the outside of the pipe, stabilizing and suspending the drill string in the rotary table.

Traditional slips require workers to manually lift and lower slips around the pipe. Once set, the driller slowly lowers the pipe, allowing the teeth to grip the string. The force wedges the slips into the taper of the rotary table’s opening to lock the drill pipe in place, effectively distributing and supporting the weight of the drill pipe. To remove slips, members of the rig crew must grasp and lift the slip handles while the driller lifts the pipe out of the rotary table opening. Once fully removed, the slips are set aside.

Unlike their traditional counterparts, power or automatic slips do not require manual lifting and setting of slips. Instead, power slips can be pneumatically or hydraulically powered and can be operated remotely using a valve or pedal control. And, by eliminating the need for manual handling slips, power slips can also help to reduce crew fatigue and increase safety on the drill floor.
