1. Casing centralizer is a cementing tool which applied to centralize casing to improving the cementing quality. Casing centralizer can be applied directly to casing to form stabilizers for drilling with casing or liner in both straight and directional wells. The popular styles available are non-welded single bow spring centralizer, and double –bow spring centralizer with high reliable quality.

2. 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.
