Hardfacing for Stabilizer:

HF1000 Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF2000 Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage -- ideal for high deviation drilling in abrasive formations.

HF3000 Tungsten carbide inserts set in a power spray deposit ideal for abrasive formation. 97% bonding guaranteed, certified by ultrasonic report. Recommended for non-magnetic stabilizers.

TCI Tungsten carbide inserts (button type). The inserts have been developed to allow cold insertion and maintain close fit. A greater concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.

Testing equipment
