CORE BARRELS & CORE DRILLING BITS

ROSCHEN offers a variety of high quality coring drilling systems which include Wireline core barrels, Double Tube core barrels, core diamond drill bits, drill rods, casings.

Brief Introductions of Core Barrels:

Roschen core barrels include wireline (Q series, AQ Core Barrel, BQ Core Barrel, NQ Core Barrel, HQ Core Barrel, PQ Core Barrel) core barrels, T2 series (T2-76/86/101/116 Core Barrel), NWM Core Barrel, LTK48, LTK60 core barrels, etc, We also provide core barrel spare parts such as core lifters, core lifter cases, stabilizer, locking coupling, adaptor coupling, landing ring, stop ring, spirol pin, etc. This kind of core drill strictly complies with the international standards.

The Wire-line core drilling tools can lift core from drill rods without picking up coring system. During this process, picking up coring system is not necessary. Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench are all belong to drill tools. A complete set of wire-line drill tools include: core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, drilling rods, inner tube, outer tube, reaming shell, core bits, circle wrench, etc. It has some advantages such as high penetration rate, high core recovery ratio, long bit life and lower labour intensity, the advantages can get more clear with the increasing of drilling hole depth.

Roschen are a professional core barrel manufacturer and supplier in the world. We have gained the recognition of a large number of clients through our 20 years' production experience and marketing and serving experience, and meanwhile we have accumulated abundant experience in terms of products. At the same time, we keep researching core barrels that can better meet the clients' needs and the market.

Features of Core Barrels:

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.

Generally, there are three kinds of core barrel depending on the core barrel tubes.

Core barrels and overshots

Roschen offers core barrel and overshot systems for vertical up (pump-in) and vertical down hole angles.

Multifunctional wireline core barrel and overshot systems

Standard and pump-in applications in a single system Interchangeable components New iQ-FCV valve - always retains the volume of water in the drill string, even in broken ground or dry holes New logic tip on overshot -allows for in-hole dry releasing of the inner tube assembly once the water level has been reached, shortening the release time Pump-in overshot features a ball valve indicator which alerts the operator of positive latching onto the core barrel's back end Comprehensive range of accessories
