Solid rigid centralizers are one series of casing centralizers, which are integral part of cementing processing. They 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. It is available in steel or aluminum materials with spiral or straight blade body construction in standard and customized sizes to match different casing sizes and wellbore conditions. Roller centralizers are also available for customers' requirements. Solid rigid centralizers are available in deviated or horizontal wells. But it is rarely selected in the vertical wells because of the smaller diameter than the wellbore.

  • The centralizer is made of stamped steel.

  • It is designed for vertical well configurations where lateral loads are at a minimum.

  • It is designed to provide a positive stand off the casing for both cased and open holes.

  • The stand off centralizer is required where close tolerance between the casing and the hole is being encountered.

  • It allows for reciprocation and rotation during cementing and can be installed between set screw stop collar.
