Product Description

                                          spiral vane cast aluminum rigid casing centralizer


Spiral Vane Solid Rigid Centralizer are designed with special angled vanes with round ends overlapping the entire 360^o open hole circumference. The spiral vanes enhance the localized turbulence, mud cake removal, even distribution of fluid around casing/ liner and provides good cementing. The spiral vanes helps it to reach TD.

These centralizers provide ultimate drag and make it preferred option for horizontal and deviated wellbores. These centralizers are available in Aluminium Alloy, Zinc Alloy, Thermoplastic and Steel Alloy material.
 

These centralizers are also available in fix style. Rows of set screws are fixed on the periphery of the centralizer which prevents rotating of centralizer against casing/liner. These centralizers are tested for reciprocating and rotating holding force capacity along with testing as per API standard.

 

This slip-on centralizer consists of a slip-on 5" long steel collar with spiraled steel bars welded onto the outside for counter-clockwise pipe rotations and to assist in creating turbulence in the annulus. These centralizers are normally run between two stop collars to provide the casing a smooth bearing surface and reduced torque. Sizes are available for all standard casing sizes. Recommended for use with all standard casing grades.



 

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. 
 

The 30° slope of the vane ends reduce drag and aid the casing in reaching TD. This gentle slope 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. 

The high grade metallic alloy centralizer can now be placed across the productive intervals allowing clean perforations without shot distortion. Casing deterioration due to electrolysis between dissimilar metals is non-existent because the metallic alloy is the softer sacrificial metal reducing casing collapse. The centralizers are designed to slip easily on the pipe's pin end. They can run free on the joint or between stop rings, or can be secured to the casing with set screws.
