6) Introduction

Casing centralizers are to help center the casing in the wellbore can be used to help align casings through well heads near surface, allowing even distribution of the cement around the casing during cementing operations.

Rigid centralizers are built out of solid steel bar or cast iron, with a fixed blade height and are sized to fit a specific casing or hole size.

7) Feature 

a. Rugged and works well even in deviated wellbores, regardless of the side force.
b. Shock, impact and corrosion resistant
c. High tensile and yield strengths
d. Available with straight or spiral blades
e. Helps ensure positive centering in deviated or horizontal holes
f. Helps prevent differtial sticking while running casing
g. Provide a guaranteed standoff and function as bearings during the pipe rotation.

8) Installation

Rigid centralizers can be installed on the casing with stop collars or with integral set screws. Installations that allow casing rotation and reciprocation are preferred because of improved displacement efficiency. Most slip-on rigid centralizers must be installed between stop collars and are freely floating there between.
