Wireline Core Drill Parts , Double Tube Core Barrel Assembly 3m - 1.5m


Specifications:


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

Description:


Standard core barrel lengths are 1.5 and 3.0 metre. Core barrel is supplied with a blank reaming shell and thread protector. Core Bits purchased separately.


designed for use with core bits with a thin cutting face in order to maximize the rate of penetration. Suitable for use with water or mud as the flushing medium.

The T2 series corebarrels are available in metric sizes 56 - 101 mm, and DCDMA hole sizes B and N. The latter are denoted TBW and TNW, respectively.

The Lifter Case is a push fit directly onto the Extension Tube. When the core is broken from the rock strata, the Lifter Case slides down to rest on the Core Bit. Thus the entire load of the core is transferred to the Outer Tube. This design is especially advantageous when working with heavy cores as it prevents overloading the bearings and thus prolongs the life of the core barrel.

The Inner Tube and Outer Tube are manufactured from cold drawn steel tube with a very high tensile strength and straightness. The Head Assembly is manufactured from heat-treated alloy steel to ensure long life.

As an option T2 series core barrels can be used with clear plastic Coreliner tubes to form an inner, triple tube.This greatly facilitates core handling and improves presentation. When Coreliner tubes are used an undersized bit and corelifter are required.

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.
