Cast Alloy Spiral Vane Solid Rigid Centralizer
Solid centralizers have proven to be the casing centralizer which eliminates secondary cement squeezing and assures zonal isolation. The solid straight blade design promotes self-cleaning in the wellbore with less fluid restrictions and drag than bow centralizers and allows pipe to rotate and reciprocate freely inside the centralizer. Solid Centralizers are the superior casing accessories, delivering 360º total cement coverage.
solid centralizers are available for casing sizes ranging from 4 ½" to 20".
Rigid casing centralizer is used in deviated wells and horizontal wells. There are several blades on the rigid centralizer that can keep casing from contacting the wellbore wall
Roller rigid centralizer which is most suitable for highly deviated wells and horizontal wells has two or three rollers in each blade. It can change slipping friction to rolling friction, so it greatly reduces the friction between casing and wellbore wall and let casing go to desired position smooth.
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.
