Integral 3-Spiral Blade Stabilizer,Integral 4-Spiral Blade Stabilizer(string type& near bit type).The working hardfacing surface(also called as wall contact)materials available separately are(1)carbide insert,(2)Inserted diamond compound,(3)Low temperature brazing tungsten carbide slug,(4)Surface bead welding abrasive welding rod etc..

Through Ultrasonic testing and Magnetic testing the bodies are proved up to grade.

Hardfacing

HF 1000

Crushed tungsten carbide held in a nickel bronze matrix. The

3 mm grain size ensures greater concentration of carbide

which is ideal for soft formation drilling.

Sections through hardfacing.

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.

HF 3000

Tungsten carbide inserts set in a powder spray deposit ideal

for abrasive formations. 97% bonding guaranteed, certified by

ultrasonic report. Recommended for non- magnetic stabilizers.

HF 4000

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.

HF 5000

This oxy-acetylene process applies tough molten carbide particles of varying sizes held in a nickel chrome matrix which provides excellent bonding properties and greater surface ear characteristics are achieved. Surface hardness levels over 40 HRC. Idear for GEO-THERMAL applications over 350°
