Wireline Double Tube Core Barrels (BQ NQ HQ PQ)
Wireline double tube core barrels are primarily used in deep
coring. With an overshot device, they eliminate the need to couple
and uncouple the rod string each time the core is retrieved.
Our head assembly features long life span, good compatibility with
parts like inner tube and outer tube from other vendors, and
availability in all spare parts.
All With ISO certificate & quality control.
