Product Description
  spiral blade aluminium alloy solid body rigid centralizer 
Spiral Blade Solid Centralizers were developed to provide better cementing in highly deviated and horizontal wells and are designed to provide optimum flow area.

The spiral solid vanes minimize casing drag and plow effect and overlap the 360 degree circumference to provide maximum wall contact and increase fluid swirl which increases the displacement efficiency.
The reduced flow area between the spiral blades produces a vortex motion of the fluids for more fluid velocity with direction.

 Spiral Blade Solid Centralizer are constructed in one-piece and are available in high strength corrosion resistant cast aluminum, non-sparkling zinc alloy or in solid steel.

Available in all sizes from 3-1/2" to 13-3/8" without or with set screws for eliminating stop collars.
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.
Available with straight blade centralizer and spiral blade centralizer
Cast steel, cast aluminum and light weight casing rigid centralizer are available
Easy to install
Can move on casing freely, also can be fixed on casing by tighten screws.
