Plastic Spiral Vane Casing Centralizer/Casing Composite Centralizer
1. Description
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.
2. 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.
