Spiral Vane Aluminium-Alloy Casing Centralizer
The centralizer are made of high strength, corrosion resistant cast aluminum. They can be used with corrosion resistant alloy casing strings to avoid the effects of galvanic corrosion. Their spiral blades increase annular turbulence to improve well bore clean out. It is developed specially for horizontal and extended reach wells with lower coefficient of friction over steel centralizers.
