SINODRILLS Atlas Copco Roc F6/L6/L8 DTH Drill Pipes

DTH drill rods transmit compressed air, so as to power the hammers to perform drilling works. Sinodrills DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe.The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.

Features

• Complete sizes for option, suitable for different types of DTH drilling system;

• The rods are made of cold-drawn steel with high manufacturing precision;

• Thread joint sturdily linked to the rod via friction welding;

• Nitriding process grants the thread joint good hardness, good wearing quality and thus long lifespan.

Applications

Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.
