Spiral  vane steel solid rigid centralizers are developed in response to  the need for better cementing in high deviated and horizontal well.Spiral vane steel solid rigid centralizers are  designed to provide optimum flow area.The 360degrees overlapping solid  vane provides  maximum wall contact and fluid swirl.Reduced flow area   between the spiral blades produces a vortex motion of the fluids for more fluid velocity with direction.The 30-degree slope of the vane end reduces drag and  aids the caing in reaching TD.
This gentle flow from the body to the  height of the vane will eliminate scraping,gouging or digging into the formation and consequently reduce balling between the vanes.Spiral vane steel solid centralizer has high impact and  shock resistance combined with tensile and yield strength as well as  resist corrosion.The Spiral vane solid rigid centralizer is normally 8" long, but it can be manufactured to any length the customer requires.
These centralizers are available with or without set screws for eliminating of stop collars.
Spiral vane solid rigid centralizers are available for casing Sizes 4 ½" to 20".Any special sizes are available on request.

igid casing centralizer 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.

5-1/2" rigid casing centralizerconsists of a rigid body, on which machined five spiral blades. There are three or four modified alloy steel, fully heat treated rollers fixed on every spiral blades. The assembly is shown as following fig. Because of rigid body and rolling friction between the rollers and inside of well or casing, the capability of the top wire casing rigid roller centralizer is better than others of all. Recommend to use the tool in deviated holes and horizontal holes.
