    Remet 4 1/2" REVERSE CIRCULATION DRILL ROD For Atlas Copco RC 50 Reverse Circulation Drilling

    Remet 4 1/2" REVERSE CIRCULATION DRILL ROD For Atlas Copco RC 50 Reverse Circulation Drilling


    Introduction

    ROSCHEN offers a complete line of premium quality reverse circulation, drill rods, in sizes from 3 1/2" to 10 3/4", and with a number of thread connections. All Reverse Circulation rods are manufactured using the most advanced technologies and specifically engineered to provide high strength, excellent wear resistance, and long life.

    RC, dual wall drill rods are manufactured with an outer drill rod and an inner tube located inside the rod. When the drill rods are threaded together, the inner tubes seal together to provide a continuous route for cuttings to travel from the bit face to the surface for collection.


    The RC method employs dual wall reverse circulation drill rods that comprise an outer drill rod, with an inner tube located inside the drill rod. The inner tubes overlap, and seal on the tube below with O rings when the drill rods are screwed together. These inner tubes provide a continuous sealed pathway for the drill cuttings to be transported from the bit face to the surface. The circulating medium, in most cases high-pressure air, enters the annulus between the rod and tube via the air swivel, which is normally part of the drill string, or sometimes mounted on top of the rotation head. The air travels down the annulus to the drilling tool, which is usually an RC hammer, or can be a blade bit or tricone roller bit. As in conventional open hole drilling, the air powers the drilling tool and the exhaust air carries the cuttings.
