Solid rigid casing centralizers Rigid 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 point. Several styles of centralizers are available for matching different well specification and hole size,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 hole and improve cement flow by reducing the effects of channeling.
