DRILL COLLAR SLIPS

TECHNICAL SUMMARY

DCS Series Drill Collar Slips are specialized clamping equipment for drill collar handling in deep and ultra-deep well operations. Adopting manual lead screw adjustment and three-piece extended slip block structure, they are compatible with 3" - 14" drill collars. Equipped with high-hardness alloy jaws (HRC58-62) and anti-slip inserts, the slips ensure strong and uniform clamping force, effectively dispersing load to avoid damage to the thick-walled drill collar. Featured with stable performance, simple operation and reliable safety, it is an ideal choice for drill collar suspension and tripping operations in high-load deep well, ultra-deep well and offshore drilling scenarios.
