NRQ wireline drill rod play an important part in N size wireline drilling. It provides the channel for NRQ inner tube assembly. It also transits the torque, drill pressure in complex and harsh conditions.

NRQ wireline drill rod tubing

●High quality alloy steel tubing

●Good concentricity, straightness and heat treatment

●Tubing properties meet the industry standard

NRQ wireline drill rod thread

●Improved NRQ tapered, course threads (3 threads per inch) ,increased taper and a reverse angle load flank provides an interlocking joint with increased strength and anti-jamming for easier make-up.

●Load efficiency of 50% provides sufficient strength for most drilling conditions

NRQ wireline drill rod heat treatment

●Provides higher material strength

●Whole rod Heat treated significantly increases rod life

NRQ wireline drill rod case hardening

●NRQ Pin thread crest is hardened to nominal 50-55 HRC to eliminate damaging’adhesion’ wear

●Eliminates the transfer of wear material back and forth as seen between threads of equal hardness, leading to large scale galling and joint seizing
