cast aluminum solid rigid centralizerApplicationCasing centralizers are to help center the casing in the wellbore, allowing even distribution of the cement around the casing during cementing operations.
Aluminum Rigid Centralizer should be used in areas where a good primary cementing job is required, including deviated and horizontal wells.
Features for Aluminum Solid Rigid Centralizers:a. Light Weight.
b. High shock, impact Resistance.
c. Optimum tensile and yield strength.
d. Anti-corrosion.
InstallationRigid 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.
