BRQ drill rod, BRQ wireline drill rod, BRQ coring rod.
BRQ wireline drill rod play an important 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.
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
●Eliminates the transfer of wear material back and forth as seen between threads of equal hardness, leading to large scale galling and joint seizing
