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

HRQ wireline drill rod tubing

●High quality alloy steel tubing

●Good concentricity, straightness and heat treatment

●Tubing properties meet the industry standard

HRQ wireline drill rod thread 

●Improved HRQ 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

HRQ wireline drill rod heat treatment

●Provides higher material strength

●Whole rod Heat treated significantly increases rod life

HRQ wireline drill rod case hardening

●HRQ 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
