Single Piece Centralizer Product Show

Shuttle bow spring

Slip on Single Piece Bow Spring Centralizer

Wearable and stable API casing centralizer

Centralizer cementing tools, it makes simple, and beautiful structure, durable, strong centering force, prone to overcome the
original welded lifter desoldering , is a kind of centralizer can ensure quality of drilling cementing. The sort is various,
according to the structure can be divided into the roller type, the sliding block type, automatic reversing type, etc. Different
structure and material of centralizer, applies to different types of eccentric wear oil well. On the part of eccentric wear
prevention, the most critical is installation location, spacing, and number.

Single Piece Centralizer Coating

Higher restoring force than API standard

Single Piece Centralizer :Shuttle Bow Spring increases restoring force

Integrate steel plate to process，Paint baking

The integral centralizer has ultra-high strength without any weak point. The centralizer provides High restoring forces while keeping starting and running forces at or near Zero lbf. This Minimizes drags during casing running and maximizes stand off during cementing operations.
Application:
Horizontal and deviated hoes, the slim and irregular holes, Oil reservoir
Advantage:
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.
