Product Description

Ordinary drill protectors are all fi xed on the drill pipe and rotate as the drill pipe. In order to reduce the

friction from the rotary drill pipe and upper casing in the horizontal well and extended reach well, we
develop the NRPs with drill pipe rotating while it idoesn't when drilling.
NRPs ensure minimal casing wear, increase stability and reduce shock and vibration in the drill string.
It consists of four parts, sleeve, upper thrust collar, lower thrust collar and alloy steel bolts.
