Product Description

Casing Accessories Slip On One-piece Bow Spring Centralizer

Introduction
The centralizers are a single / one-piece, slip-on, close tolerance bow spring design, made from low alloy and low carbon (Heat-Treated) steel.

Applications
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.

Advantages
Available in 4 ½" to 20" sizes. Customized sizes are also available.
The one piece construction results in a robust centralizer that can withstand immense forces, remain intact, and never leave debris in the hole.
Optimum standoff capability in even the most challenging well conditions.
At or near zero starting and running forces.
Minimal cross-sectional area minimizes flow restrictions and increase equivalent circulating densities.
All sizes have been tested and validated to exceed API Spec 10D.
