Unibody Bow Spring Casing Centralizer Made of Seamless Pipe

1. Type: Single (One) Piece Bow Spring
 
2. Materials: 65Mn steel
 
3. Specifications: 4 1/2''---20'', or others as required
 
Introduction
Unibody Bow Spring Casing Centralizer is designed for deviated and horizontal holes. The centralizer provides high restoring forces while keeping starting and running forces at or near 0 lbf. This minimizes drag during casing running and maximizes standoff during cementing operations.

All Centralizers undergo a special iron phosphate coating process to prevent corrosion and are then coated with a special polyester powder.

Unibody Bow Spring Casing Centralizer is shipped in assembled condition only. They are available in all sizes ranging from 4 ½" to 20". Any special sizes or combination can be made available upon request.
 
Applications
Unibody Bow Spring Casing Centralizer is Utilized in lean-profile drilling applications where centralizers are needed to pass through narrow / close tolerance sections, and then ultimately provide effective centralization of casing in under-reamed hole sections. Designed to meet and exceed today's most challenging well construction designs with proven performances.

 
Features, Advantages, and Benefits
· The advanced, versatile design of the centralizer enables customization for unique or critical applications.
·  The proprietary fillerless welding technique used to form the centralizer body results in a weldment virtually indistinguishable from the parent metal.
·  The one-piece construction results in a robust centralizer that can withstand immense forces, remain intact, and never leave debris in the hole.
·  Minimal cross-sectional area minimizes flow restrictions and increases equivalent circulating densities.
·  The single piece centralizer provides high restoring forces and 0 lbf running force.
·  All sizes have been tested and validated to exceed API Specification 10D.
