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
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.
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.
