2.Product detail
Casing centralizers
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.
The Roller Casing Centralizer consists of rigid body, on which machined five spiral blades or straight blades. There are three modified alloy steel, fully heat treated rollers fixed on every blade. Because of rolling friction between the rollers and inside of well or casing, the capability of the RCR Centralizer is better than others of all. Recommend to use the tool in deviated holes and horizontal hole.

2. 3-section force and restoring force conform to API standards.
3. Starting force and restoring force conform to API standards.
