DCDMA Standard B N H P Wire - Line Core Barrel Used In Mineral Exploration Deep Hole

Specifications:

1. high quality alloy tube
2. thru-wall heat treated tube body
3. consistent concentricity, straightness
4. tapered threads

Wire-line core drilling equipment is very commonly used for mineral exploration for deep holes because of practical usage.

Sinocoredrill products are manufactured by using high quality raw materials and designed according to DCDMA ,wire-line –Q standard.  

We offers to clients following models of wire-line core barrel compatible with -Q Wire-line Standard Drilling Equipment;

Wire-line Double Tube Core Barrel; B, N, H, P sizes;

Wire-line Triple Tube Core Barrel; B-3, N-3, H-3, P-3 sizes;

Wire-line Core Barrel T2-76, T2-86, T2-101… T series;

Wire line core barrels are used when coring to greater depths, mainly because they eliminate the need to couple and uncouple the rod string each time the core is retrieved. An overshot device is dropped on a cable and directly couples onto the inner tube assembly, allowing fast retrieval of the core after each core run. Available in DCDMA sizes B, N, H. and P.

1) High penetration rate and high drilling efficiency.

2) High core recovery rate.

3) Long bit life and lower labor intensity

4) Adopt abrasion resistant material.
