Product Overview
DCS Type Drill Collar Slips are rotary table slips used to grip and support drill collars in oil and gas field operations. Rig crews use them when preparing the drill string, making connections, performing tripping operations or handling heavy tubulars on the rig floor.
Drill collars are heavier than regular drill pipe, so they need stable and properly matched handling tools. A suitable set of API 7K drill collar slips helps crews keep the drill collar under better control, reduce slippage risk and improve daily tubular handling efficiency.
SGPE DCS drill collar slips match different drill collar OD ranges and work with corresponding insert bowls. DCS-S covers smaller drill collar sizes, DCS-R covers common medium-size ranges, and DCS-L handles larger drill collars used in deeper wells and heavier drilling environments.
