Product Description

Straight Blade Cast Steel Solid Body Centralizer for Oilwell Cementing

Description of solid rigid centralizer
Rigid centralizers are with high supporting force and low starting force , thus enabling the casing smoothly down and at the same time stay at a high level.
Sizes ranging from 4-1/2" to 20", custom size are available 
Spiral vane: reducing drag force.
 
Feature of cast steel straight vane centralizer
1. Application:in deviated and horizontal wells, liner overlaps, and shoe joints.
2. Suitable for either cased or open hole.
3. Made of high tensile, solid, cast steel, for shock, impact, and corrosion resistance.
4. Vane ends are beveled 30 degrees relative to casing centralizer to provide excellent lead into restrictions, and reduced drag when running into hole.
5. Wide vanes distribute load from the casing string into the well bore without gouging.
6. The design of the vanes keeps running forces at a minimum.
 

Feature of cast steel Spiral vane Solid Rigid Centralizers
The 360 degrees overlapping solid vane provides maximum wall contact and fluid swirl. Thus reduced flow area between the spiral blade and produces a vortex motion of the fluids for more fluid velocity with direction.
