High Quality Customized Size Casing Centralizer API Standard Casing Centralizer for Drill Pipe

Product Introduction

• 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.
