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