Product Description
Oilfield Equipment Solid Rigid GF Centralizer with Rollers

Introduction

Solid rigid centralizers are built out of solid steel bar or cast iron or other solid material, with a fixed blade height and are sized to fit a specific casing or hole size, to help center the casing in the wellbore.
Roller Centralizers are solid rigid Centralizers designed with rollers on the vanes of the centralizer.
 
Features for solid rigid centralizers with rollers:
a. Change slipping friction to rolling friction to reduce the friction and let casing go to desired position smoothly.
b. Remove wellbore cake and improve mud replacement efficiency etc.
c. Provide superior wear resistance.
d. Remain functional throughout the life of the well.
e. Able to aid in casing/tubing retrieval.
f. Roller/axle relationship ensures that axle shear stresses remain within elastic limits, preventing permanent deformation.
g. Axles are crimped in place, eliminating the welding process, while ensuring the rollers cannot be broken and fall into the wellbore freely. 
h. High pressure and high temperature resistance with high quality material.
