Reverse Circulation Down The Hole Hammer Inner Tube And An Outer Tube

Down The Hole Hammer Introduction

Reverse circulation RC drill pipe consists of two main components, an inner tube and an outer tube. Reverse circulation drill pipe is a dual wall pipe capable of being pressurised and not losing its pressure between joints. This is done by welding components of the inner tub and outer pipe together but allowing air to pass between them. This allows you to collect continuous uncontaminated samples. This also reduces the amount of air that is required.

Roschen also offers a concealed inner tube reverse circulation system that has a great deal of technological advancement compared to other reverse circulation systems including a system to perforate the water in the central column. It allows to create a stronger vacuum to force cuttings up the inner pipe - better, easier to use, reduction in vibrations and reduction in overall wear compared to other Reverse circulation RC pipe systems.

Down The Hole Hammer Feature

VALUE ADDED

1. Lower fuel consumption
2. More responsive drilling
3. Up to 15% higher penetration rate
4. Less prone of breakage

Advantages:

1. Low air consumption (15% less than before)
2. Faster building up of air pressure
3. Higher frequency means more impact/minute
4. Increased power output

RH560 A BIG HAMMER WITH BIGGER ADVANTAGES:

1. Simple overall design minimizes failures
2. Optimized, piston and bit design maximizes energy transfer efficiency
3. Higher penetration rate up to 15%
4. Low air consumption meaning less fuel consumption yet more power
5. No foot valve meaning no small parts causing unnecessary breakdown
6. Less downtime means less handling of the hammer, lower injury risk
