Zinc Alloy Spiral Vane Solid Rigid Centralizer
We fabricate Zinc Spiral Vane Solid Rigid Centralizer are designed from our experts and provides efficient functionality. These are checked on a regular basis and that are used in different industrial applications.
The offered zinc spiral vane solid rigid centralizers are simple and convenient, extensively used for rough and fine polishing of metallurgical specimens. They are available at cost effective price.
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 Roller Casing Rigid Centralizer consists of rigid body, on which machined spiral blades.
There are thermoplastic, fully heat treated rollers fixed on every spiral blades.
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/Wheeled centralizers are mainly used for big high Roller, high deviated wells and horizontal wells, to centre casings.
Features
1. Spiral blades increase annular turbulence.
2. With the shape of stream-lined, it enables casing run easily in wellbore.
3. Both straight blade and spiral blade are available.
4. The material can be cast steel or cast aluminum.
This centralizer should be used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps, and shoe joints. They are suitable for either cased or open hole. These are made of high tensile, solid, cast aluminum, for shock, impact, and corrosion resistance.
Vane ends are beveled 30 degrees relative to casing centerline to provide excellent lead into restrictions, and reduced drag when running into hole. Wide vanes distribute load from the casing string into the wellbore without gouging. It is made of softer material than wellhead equipment to avoid damage to the wellhead when running through. Has provided excellent results in extended reach and horizontal applications. The design of the vanes keeps running forces at a minimum. Any special sizes or combination can available on request.
