Spiral Vane Thermoplastic Composite Centralizer Casing
Centralizers are an integral part of the cementing process. They provide the mechanism that centers the casing in the hole and allows uniform cement flow around the casing to help protect it at all points. Several styles of centralizers are available for matching different well specifications and hole sizes, including turbulence generating designs that help clean the annulus and distribute the cement more evenly and uniformly. All models offer ample clearance for fluid passage and are extra effective in centering the casing, even in highly deviated holes and improve cement flow by reducing the effects of channeling.
Features
1. Spiral blades increase annular turbulence.
2. With the shape of stream-lined, it enables casing run easily in wellbore.
3. Both straight blade and spiral blade are available.
4. The material can be cast steel or cast aluminum.

Our composite centralizers provide the following benefits:
Reduce total well construction costs - eliminate the need for expensive casing couplings
Enables casing or screen deployment in longer reach wells - industry leading low friction factors reduce torque and drag, enabling the user to reach total depth
Zero corrosion - totally non-metallic material removes the contamination risk to carbon or expensive hi-chrome content steel tubulars and completion equipment
Low wear and material loss - low friction factors and advanced material formulations result in low wear
High impact and side load resistance - longer lasting
Light weight - the size to weight ratio is significantly lower than metallic centralizers which reduces freight and handling costs
Specific OD's can be accommodated - composite material can be machined down to meet requirements.
