Description

Atlas Copco RC 50 Remet 4 1/2" Oil Drill Pipe

Heat treatment control:


Heat treatment will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body. After heat treatment, strength, hardness, straightness and concentricity of the treated tubes will be tested in our lab.

Introduction

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.
