Type SD Rotary Slips
The type SD rotary slip is commonly involved in the oil and gas drilling operations, and it is adopted to hold drill pipes to make up or break out connections. Thisrig handling tool is applicable for drill pipes whose diameter range is within 23/8-51/2 inches (60.3-139.7mm).
Classification and Application
Based on the gripping length, our rotary hand slip is divided into three models which are SDS (short), SMDL (medium) and SDXL (extra long), and these rotary slips are designed for different wells respectively. More specifically, SDS slips are suitable for shallow wells, SDML slips are intended for medium depth wells while SDXL slips are for deep wells.
