API Stabilizer forging for oilfield drilling
Forged step bar for oilfield stabilizer
Brief introduction of the oilfield stabilizer
Integral Spiral Blade Stabilizer: It is devided into integral 3-spiral blade stablizer, integral 4-spiral blade stablizer. There
are four kinds of abrasive resistant materials on the working surface of stabilizer: Insert tungsten carbide buttons,
insert diamond compound body, low temperature welding tungsten carbide pieces, hardfacing electrode on the
surface and so on.
The spec. of the stabilizer stated in the order
