HRQ drill rod

HRQ drill rod, HRQ wireline drill rod, HRQ coring rod.

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 damagingadhesion 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
