Tubular Handling Tool API 7K Drill Pipe Slip, Rotary Slip SDML/ SDXL 2 3/8''~7''
Drill pipe slips, also called rotary slips, are suitable to handle the drill pipe during the oil well drilling operations for the exploration of petroleum and natural gas. It is an essential tool for coupling and uncoupling.
Drill pipe slips type SD can accommodate drill pipes from 2 3/8’’ to 7’’ (60.3 to 177.8mm). They are classified as type short (SDS), Medium (SDML), Extra Long (SDXL) according to the gripping length. SDS slips are designed for shallow hole drilling, SDML slips are the perfect choice for all medium depth drilling and SDXL slips are designed for deep drilling. Suitable slips should be selected according to the OD of the drill pipe and the Max. load.
