Introduction

Pneumatic slip —XDQW-20 can be match with service rig and tractor hoist, which is placed into the BOP flange or rotor of service rig. While working the slip body goes down along the pyramidal face of slip bowl, moves drill pipe to close the center and finally grasps it; on the contrary, it goes up along the pyramidal face of slip bowl, as a result of expanding outward and providing way for pipe moving, the grasped drill pipe is released and goes through the air slips. The slip body is elevated and lowered by elevation and subsidence of the piston rod.

In addition, it has characteristics of small volume, light weight, strong load-carrying capacity, easy operation pneumatically or manually and safe and reliable performance.
