BQ wireline drill rod plays an important role in B size wireline drilling. It provides the channel for BQ inner tube assembly. It also transits the torque, drill pressure in complex and harsh conditions.

BQ wireline drill rod tubing

●High quality alloy steel tubing

●good concentricity, straightness and heat treatment

●tubing properties meet the industry standard

BQ wireline drill rod thread

●Typical BQ tapered, course threads (3 threads per inch) provides easy make and break

●Load efficiency of 30% provides sufficient strength for most drilling conditions

BQ wireline drill rod heat treatment

●Provides higher material strength

●Whole rod Heat treated significantly increases rod life

BQ wireline drill rod case hardening

●BQ 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
