NQ3 HQ3 PQ3 AQ NQ HQ PQ For Mining Drilling
Induction:
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.
The necessary test equipment and the effective & perfect production
process control is the assurance of product quality. Taking the spirit of "To win the market with
innovation, to serve the customers with friendship, to build the brand with quality, to develop
the enterprise with sincerity", we utilize the advanced testing methods to make each product
meticulously.
All With ISO certificate & quality control.
