Product Description

 

Casing Accessories Steel Roller Solid Body Centralizer Supplier1
1. Type: Rigid casing centralizer with rollers

2. Material: Cast steel, Nylon, Aluminum, Zinc Alloy

3. Standard: API, or others as required
 
4. Specifications: 4 1/2''--- 20'', or others as required

5. Introduction
Rigid centralizers are made of solid steel bar or cast iron or other solid materials, with a fixed blade height. They are sized to fit a specific casing or hole size and help center casing in wellbore.
Roller centralizers are rigid centralizers designed with rollers on the vanes of the centralizer.

6. Characteristics:
1) Change slipping friction to rolling friction to reduce the friction and let casing go to desired position smoothly;
2) Remove wellbore cake and improve mud replacement efficiency;
3) Provide superior wear resistance;
4) Remain functional throughout the life of well;
5) Be able to aid in casing/tubing retrieval;
6) Roller/axle relationship ensures that axle shear stresses remain within elastic limits, preventing permanent deformation;
7) Axles are crimped in place, eliminating welding process, and ensuring the rollers cannot be broken and fall into wellbore freely; 
8) High pressure and high temperature resistance with high quality material.

7. Installation
Rigid centralizers can be installed on the casing with stop collars or with integral set screws. Installations that allow casing rotation and reciprocation are preferred because of improved displacement efficiency. Most slip-on rigid centralizers must be installed between stop collars and are freely floating there.
