Triple Tube Core Barrels (Standard)
The Triefus Triple Tube Core Barrel, as described in figure 1, was developed nearly sixty years ago in conjunction with the snowy mountains hydro electric authority and the joint coal board of Australia for coring the badly weathered and decomposed granite in south eastern new south wales ‘from the grass roots down’.

The cutting sizes AMLC, BMLC, NMLC and HMLC are to international standards and are used with standard W series casing. Water Ends are threaded to accept W series drill rods. From 2C to 8C the barrels are supplied with rod connections specified by the client.
The letters ‘LC’ used in the reference nomenclature refer to ‘Large core’ to differentiate between the original double tube core barrels (NM etc.) in which the core diameter was much smaller than that obtainable with these barrels.
All Triefus Triple Core Barrles are normally supplied with steel split inner tubes; however plastic (non-split) inner tube is available in NMLC size and stainless and hard chromed split tubes can be supplied for most other sizes. The plastic inner tube is used in NMLC triple tube core barrels where it is desired to retain the core exactly as it is recovered from the hole. The core is not removed from the plastic inner tube which is sealed at each end and despatched undisturbed to the laboratory. Because the plastic is clear and only 1 mm thick, visual examination of the core is possible at the drill site.
The outer tubes of all Triefus Triple Tube Core Barrels are hard faced at each end. Staggered hard facing over the full length of the outer tube can be supplied if required.
