T6 Series Core Barrel

T6 series double tube core barrels are of sturdy design suitable for coring in all formation types. Suitable for use with water, mud or air as the flushing medium. When used with air flush oversize bits and pilot-type lifter case is required.

The T6 series corebarrels are available in metric sizes 101 - 146 mm, and DCDMA hole size H. The latter is denoted T6-H.

The Lifter Case is a push fit directly onto the Extension Tube (T6-101 and T6-H lack an extension tube. The lifter case fits directly onto the inner 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 T6 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.
