Casing Centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the Casing Centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.
