Description

Product Description

Casing centralizer as a cementing tool is applied in vertical, deviated and horizontal wells to centralize casing for improving the cementing quality. The cement could be concreted firmed between casing and borehole wall. It can be installed on casing joint or any position working with stop collar for centralizing. Our centralizer with API standard sizes range from 4-1/2" to 20" and surface is coated by powder baking or paint baking. The products have high tensile and yield strength, shock, impact and corrosion resistance performance.

Bow type Centralizers

The bow springs of this centralizer have two types as follow: non-welded single bow spring centralizer 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.
