Casing Centralizer with Coating
•Casing centralizer is a cementing tool which applied to centralize casing to improving the cementing quality.
•They are designed for High Restoring Force and Low Starting Force for centralizing the casing pipe in a Horizontal and Deviated well.
•This slip-on centralizer features a long Aluminum collar with spiraled bars to assist in either clockwise or counter-clockwise pipe rotation and to create turbulence in the annulus. It is normally run between two stop collars to provide the casing a smooth bearing surface and reduced torque.
Casing Centralizer with Coating
1.Available in sizes 4-1/2" to 20". 2.With Coating Surface. 3.Good corrosion resistance. 4.Reducing drag force.
