Product Description

RC Drill Rods & Reverse Circulation Double Wall Drill Pipes

 
REVERSE CIRCULATION DRILLING RODS
 
ROSCHEN reverse circulation heavy duty drill pipes outclass similar products on the market in both value and quality. Drilling Supply Store RC drill rods also provide the driller with excellent durability, thanks to the highest quality products which were used during the manufacturing process. Nearly 100% of our sales are direct to drilling contractors, whom openly specify our RC drilling pipes, because they last longer and drill deeper with the same air, offering the most value for the price. Additionally, our drill rods were designed specifically for RC drilling and are available in the reverse circulation drilling string configurations shown below.
 
Double Wall Drill Pipes are used in drilling of wells with diameter 84 and 93 mm and depth up to 300 m in soils of II-V drill ability classes with seams of soils up to VII drill ability class in the fulfillment of all necessary prospecting and geochemical operations, in geological mapping and exploration of deposits of solid minerals.
 
Drilling of wells is carried out with hydro-transport of the core delivered on the surface along the internal channel of the double drill string.
