Product Description

LUHAI provides integral straight blade stabilizer, integral spiral blade stabilizer, replaceable sleeve stabilizer, non-rotary stabilizer, diameter changeable stabilizer etc. There are Five kinds of hard facing(HF***0,HF***0,HF***0,HF***0,HF***0). All above products are manufactured according to API Spec 7 standard.







The working surface has five kinds of hard facing:







HF***0



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







HF***0



Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a great depth of carbide coverage-ideal for high deviation drilling in abrasive formations.







HF***0



Tungsten carbide inserts sets in a powder spray deposit ideal for abrasive formations.*7% bonding guaranteed,certified by ultrasonic reports. This kind is recommended for non-magnetic stabilizer.







HF***0



Tungsten carbide inserts ( type), The inserts have been developed to allow cold insertion and maintain close fit. A great 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***0



This oxy-acetylene process applies tough molten carbide particles of varying sizes held in a nickel chrome matrix which provided excellent bonding properties and greater surface wear characteristics are achieved. Surface hardness levels



over *0HRC.Ideal for geo-thermal applications over **0°C.
