STEEL DRILL RODS OF NON-STANDARD RAW |
Steel drill rods of non-standard raw are designed to be used in repairs of oil and gas wells in the processes of drilling cement well bores. The rods also can
be used in the drilling of oil wells up to 1000 m in depth.
FRICTION WELDED TOOL JOINTS
Friction welded tool joint with the body of the rod makes the connection
between the rods more durable.
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 è up to 800 make ups.
