ORCHID ENERGY-Hardfacing

HARDFACING

TECHNICAL SUMMARY

The stabilizer hardfacing can be divided into two categories according to different processing methods: traditional alloy inlaid column type and overlay welding type.
The traditional embedded stabilizer cannot be repaired after wear, while the hardfacing of the welded stabilizer can be removed by air gouging and then re sprayed for repair. The repair life is generally 3-4 times. The service life of the hardfacing stabilizer for overlay welding is longer, which can greatly reduce drilling costs and save expenses.
At present, various hardfacing is uniformly numbered as HF1000-HF6000 internationally. The larger the number of the hardfacing, the better its wear resistance, among which HF4000 is a traditional inlay alloy column type.

HF1000

HF1000

Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

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.

HF2000

HF3000

HF4000

HF5000

HF3000

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.

HF4000

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.

HF5000

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. Ideal for GEO-THERMAL applications over 350°.
