Wireline Triple Tube Core Barrels NQ3 HQ3 PQ3 For Mining Drilling
Wireline triple tube core barrels are generally required in broken,
fractured formations. They incorporate a third, split inner tube on
base of wireline double tube core barrel. This can be pumped out of
the inner tube after retrieval, allowing the core to be examined in
its in-situ state.
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.
