BQ Outer Tube 3.0M

With the substantial increase of medium and deep hole geological core drilling workload,we produce a complete line of single, double and triple tube core barrels.

Wireline core barrel is characterized by "three high and one low", that is, high drilling speed, long service life of diamond bit, high time utilization rate and low labor intensity. Therefore, it is widely used in geological prospecting, coalfield exploration and other fields.

We can produce all series,like B,N,P,H sizes.

Wireline coring drill pipe is a method of taking out core from hole bottom without raising drill bit and drilling tool.
