Ordinary drill pipe protectors are fixed on the drill pipe body and rotate with the rotation of the drill pipe. In order to reduce the wear of the upper casing caused by the rotation of the drill pipe during the drilling process of horizontal wells and large displacement wells, and to minimize the frictional resistance caused by this rotation wear, a non rotating drill pipe protector has been developed. Non rotating drill pipe protectors can reduce drill string torque and decrease wear between drill pipes and casing. The drill rod protector consists of a central movable sleeve (protective sleeve), a metal reinforced liner, and a limit clamp.
