Integral Blade Stabilizer

Size: Up to 36”

1. Stabilizer forging/blank, Reamer Forging
2. Integral Blade Stabilizer
lIntegral spiral stabilizer
lInterchangeable sleeve stabilizer
lStraight blade stabilize

All of the connections are strictly in accordance with API Standard, which have stress relief groove and are cold rolled. The flank of thread is phosphatized or plated copper, coated with thread dope and equipped with thread protector. It is mainly the spiral blades (usually three blades, also can be four blades will according to customers’ requirements), which rub against the borehole wall. The working surface of the blade is hard faced. The hardfacing type we can provide are HF1000, HF2000, HF3000, HF4000, HF5000, HF6000. It is preferred operation that tungsten carbide inserts are cold inset into the working surface of blades including its bevels. Braze welding tungsten carbide grains are also adopted according to customers’ requirements.

Inquiry and order should specify:
lHole size and type of stabilizer( string or near bits)
lMaterial (steel or Non Mag.)
lOD and ID
lConnections type and size
lFishing Neck OD and length
lAPI stress relief groove
lOpen or tight design
lRight or left hand spiral
lHard facing type
lFloat valve and hole
We also can make the Impact value under -20(negative) low temperature according to the requirements of clients. The average impact value is about 30J.(This only for 4145H Mod.)
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.

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 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 wear characteristics are achieved. Surface hardness levels over 40HRC. Idear for GEO-THERMAL applications over 350°

HF 6000
This process is a highly automated way of applying hard face and utilizes a combined arc/plasma stream on the work piece surface. This results is low base metal dilution and a dense,
uniform coating, the filling medium can be variety of hardfacing consumables.
