Straight Vane solid rigid centralizer is designed to provide the right feature to achieve a good primary cementing job with maximum wellbore standoff using suitable functionality. It provide ultimate drag and torque reduction with maximum fluid by pass.
It has high axial load strength. These are available in different material grades. Construction provides superior toughness.
Welded Spiral Vane Solid Rigid Centralizer is designed with rows of set screws on the outer periphery of centralizer to restrict rotation. It can be easily converted from fixed to non fixed design by detaching set screws and positioning with stop collars.
All centralizers are stored painted or coated with polyester powder. These are available in different material grades.
Solid Heavy duty Spiralizer are specially designed for extra heavy load in highly deviated Horizontal well and for use with Liner Hangers. Hydrodynamic shapes of spiral fins allow optimal mud displacement and minimal pressure drop across centralizer. Wide symmetrical Spiral fins are welded to the one piece rolled formed Sleeve under required temperature and condition, which assures ultimate strength and uniformity in every weld.
The heavy steel construction is highly effective as compare to other alloy. Solid Spiralizer are provided for direct installation on the pipe by slipping on and can be provided with compatible Stop Collars. These centralizers undergo a special Iron Phosphate coating process to prevent from Rust then coated with special Polyester Powder.
Spiralizer is designed especially for highly deviated or horizontal wells. The fins glide smoothly in the low side of horizontal bore holes. Wide symmetrical fins are smoothly beveled on the both ends to have lower coefficient of friction and to ease casing movement in either direction. Slip On Spiralizer are provided for direct installation on the pipe by slipping on and can be provided with compatible Stop Collars.
The steel construction ensures extra strength and superior toughness. These Centralizers undergo a special Iron Phosphate coating process to prevent from Rust then coated with special Polyester Powder.
Stand Off Band is designed to provide a positive stand off the casing for both cased and open holes. These Stand off Band is require where close tolerance between the casing and the hole is being encountered. The angled fins provide increased turbulent flow.
Mainly it's designed for the liner applications. Design of the stand off Band allows for reciprocation and rotation during cementing and can be installed between Set Screw Stop Collar. These Stand Off Band undergo a special Phosphate coating process to prevent from Rust then coated with special Polyester Powder.
Low Torque Roller Centralizers are specially designed to run in deviatedor horizontal sections and are effective in reducing friction. When casing equipped with Roller Centralizer runs into a deviated or horizontal hole, the sliding friction between the casing and the borehole is converted into rolling friction. Torque reduction is provided by vertical alignment of rollers on the periphery of roller centralizer.
When running cases, irregular hole diameters can lead to the wall of the borehole having an impact force on the spiral centralizer. The use of rollers significantly reduces this impact.
Low Drag Roller Centralizer is a complete mechanical friction-reduction solution designed for extended-reach wells. The contact area of the rollers with the casing or borehole wall functions well in under pressured conditions, where the risk of differential sticking is high.
The Low Drag centralizer helps to avoid ploughing through wellbore material that has settled, alleviating major drag problems in deviated and horizontal wells. In Low Drag Roller Centralizer, all rollers are arranged in horizontal direction. This kind of arrangement of rollers efficiently reduces dragging force.
