Integral blade stabilizer
The integral blade stabilizer has a single piece body made of 4145H modified alloy steel, fully heat treated to 285-341 Brinell hardness and 40 ft x lb minimum impact strength. Integral stabilizers are available in either open design or tight design, near bit or string type. Connections are gauged to API standards. And their Stress relief grooves are cold rolled. Connections are phosphatized or plated copper, coated and equipped with thread protectors.
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 3mm grain size ensures greater concentration of carbidewhich is ideal for soft formation drilling.
Sectons through hardfacing
HF 2000
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 fomations.
Sections through hardfacing
HF 3000
Tungsten carbide inserts set in a powder spray deposit idealfor abrasive fomations. 97% bonding guaranteed, certified by ultrasonic report. Recommended for non-magnetic stabilizers.
Sections through hardfacing
HF 4000
Tungsten carbide inserts (button type). The inserts have been developed toallow cold insertion and maintain close fit. A greater concentration of insertson the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.
Sections through hardfacing
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 wear characteristics are achieved. Surface hardness levels over 40 HRC. ldear for GEO-THERMAL applications over 350°
