Puyang zhongshi API Certificated Carbon Steel Centralizer Spiral Vane Rigid Centralizer Casing Roller1



Solid Casing Centralizer description:

Solid rigid Centralizers serve the purpose of centering the casing in the wellbore and are constructed from robust materials such as solid steel bar, cast iron, or other durable substances. These centralizers have a fixed blade height and are precisely sized to fit a specific casing or hole size.

On the other hand, Roller Centralizers are a type of solid rigid centralizer that feature rollers attached to the vanes of the centralizer. These rollers facilitate smoother movement and rotation of the casing during installation and operation.

Solid centralizer type:

1. spiral vane solid centralizer

2. straight vane solid centralizer

Features
a. By changing slipping friction to rolling friction, the amount of friction is reduced, allowing the casing to smoothly move to the desired position.
b. The presence of roller centralizers helps remove the wellbore cake and enhances the efficiency of mud replacement.
c. These centralizers offer excellent wear resistance, ensuring they can withstand harsh conditions.
d. Roller centralizers remain fully functional throughout the entire lifespan of the well.
e. They are capable of assisting in the retrieval of casing or tubing when needed.
f. The roller/axle relationship is designed to ensure that shear stresses on the axle remain within elastic limits, preventing any permanent deformation.
g. The axles of roller centralizers are securely crimped in place, eliminating the need for welding. This design ensures that the rollers cannot break or fall freely into the wellbore.
h. Roller centralizers are constructed using high-quality materials that provide resistance to high pressure and high temperatures.

Installation

Roller centralizers can be affixed to the casing using stop collars or integral set screws. It is generally preferred to opt for installations that permit casing rotation and reciprocation as they enhance displacement efficiency. Unlike slip-on rigid centralizers, which are typically placed between stop collars and float freely in that space, roller centralizers offer more flexibility in terms of installation options.
