 Rotary Slips are conventional tool for handling tubing, drill pipes and casing drilling operation, and are necessary tool for coupling and uncoupling operation. Drill Pipe Slips or Rotary Slips can accommdate drill pipe from 2 3/8in-5 1/2in(60.3mm-139.7mm)O.D..They are classified as type short(SDS),Medium (SMDL) and Extra Long(SDXL) according to gripping length.SDML slips are the perfect choice for all medium depth drilling.SDXL slips are designed for deep drilling.Executive standard:API Spec 7K.
