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.
The bow springs of this centralizer have two types as follow: non-welded single bow spring centralizers and non-welded double bow
spring centralizer. The centralizer are attached to the end rings without welding. The bow spring casing centralizer bow end is
connected to the end rings with a locking tab that bears the load force on the centralizer. The centralizers are supplied in
hinged segments joined by hinge pins in each segment. All non-welded centralizers meet or exceed the requirements of API
Specification 10D, which dictates the minimum restoring and maximum starting forces for centralizers for various casing / hole
size combinations.
