DOUBLE LIGHT ALLOYED DRILL RODS |
These rods are designed for Russian KGK complex for drilling the wells with diameter 84 mm and 93 mm and for the depth up to 300 m. Drill rods are needed in geological mapping and exploration of deposits of solid minerals. Drilling of wells is carried out with hydro-transport of the
core sample which is delivered on the surface along the internal channel of the double drill string.
EXCELLENT COAXIALITY AND STRAIGTHNESS
FRICTION WELDED TOOL JOINTS
Friction welding tool joint with the body of the rod makes the connection between the rods more durable.
DOUBLE DRILL ROD FOR HYDRO-TRANSPORT OF CORE SAMPLE
HEAT TREATED AND CARBONITRADED
The body of the rod is quenched and tool-joint is heat treated and quenched and thread is carbonized adding to overall wear resistance of the drill string. The hardness of carbonized tool joint is 55HRC up to 800 make ups.
