BRQ wireline drill rod tubing

●High quality alloy steel tubing

good concentricity, straightness and heat treatment

tubing properties meet the industry standard

BRQ wireline drill rod thread

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

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

BRQ wireline drill rod heat treatment

Provides higher material strength

Whole rod Heat treated significantly increases rod life

BRQ wireline drill rod case hardening

BRQ Pin thread crest is hardened to nominal 50-55 HRC to eliminate damaging ‘adhesion wear
