Material: AISI 4145H, AISI 4145H Mod, AISI 4340, AISI 4140-4142 and Non-magnetic.

Size: Up to 36”

Type:

1. Stabilizer forging/blank, Reamer Forging
2. Integral Blade Stabilizer

l Integral spiral stabilizer

l Interchangeable sleeve stabilizer

l Straight blade stabilizer

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.

ALSO WE CAN SUPPLY DS-1 and NS-1 STANDARD STABILIZER.

Inquiry and order should specify:

l Hole size and type of stabilizer( string or near bits)

l Material (steel or Non Mag.)

l OD and ID

l Connections type and size

l Fishing Neck OD and length

l API stress relief groove

l Open or tight design

l Right or left hand spiral

l Hard facing type

l Float 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.

Sections through hardfacing.

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 40

HRC. 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.
