Casing centralizer as a cementing tool is applied in vertical, deviated and horizontal wells to centralize casing for improving the cementing quality. The cement could be concreted firmed between casing and borehole wall. It can be installed on casing joint or any position working with stop collar for centralizing. Our centralizer with API standard sizes range from 4-1/2” to 26” and surface is coated by powder baking or paint baking. The products have high tensile and yield strength, shock, impact and corrosion resistance performance.
Roller Centralizer Spiral Vane Roller Centralizer consists of rigid body, on which machined spiral vanes. There are modified alloy steel, fully heat treated rollers fixed on every spiral vanes. Because of rigid body and rolling friction between the rollers and inside of well or casing. The capability of the roller Centralizer is better than others of all.
Roller centralizers are mainly used for big high Roller, high deviated wells and horizontal wells, to centre casings.Roller Centralizers can also remove wellbore cake and improve mud replacement efficiency etc.Roller Centralizers provide superior wear resistance and have been proven to remain functional throughout the life of the well and can aid in casing/tubing retrieval.
Precision-machined inside diameter fits over the casing through the complete API tolerance range, providing excellent rotational performance in mud.
When running casing through open hole, the system’s smaller roller-contact area reduces the risk of differential sticking and maintains standoff. The roller/axle relationship ensures that axle shear stresses remain within elastic limits, preventing permanent deformation.
Axles are crimped in place, eliminating the welding process, while ensuring the rollers cannot break free and fall into the wellbore. The system's high-quality construction materials improve high-pressure/high-temperature capabilities.
Roller Centralizers are available in sizes 4½" to 20". Any special sizes are available on request.
Solid Rigid Centralizer Steel Type
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.

PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
Composite Centralizer
The composite centralizer is used during running and cementing operations to centralize casing.
Made of advanced composite, the one-piece centralizer has a low coefficient of friction, is heat resistant, and is highly durable. The composite material performs reliably even in extreme wellbore conditions.
Unlike many plastic centralizers, this centralizer withstands high-impact loading and is highly wear resistant.The centralizer enables casing strings to reach total depth efficiently, provides optimal standoff for mud displacement, and greatly enhances cementing operations.
The composite centralizer has a smooth, tapered construction to easily pass obstructions in the wellbore, which makes it well suited for horizontal applications.
