    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.

    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.
