Product Description
                single piece centralizer with PTFE coatings 

The elastic casing centralizer of our company uses heavy-duty springs to support the casing, which keeps the casing in the center for improved the centralizing performance.
 
Main features
Pressed by the mold, without welding and rivets, so the centralizer has a solid structure;
The centralizer has a trivalvular structure, which makes it easy for shipping;
The starting force and the reset force are both in accordance with the API standards;
Convenient Installation;
The displacement efficiency is improved more effectively with a spinning disk.

 The roller/axle relationship ensures that axle shear stresses remain within elastic limits, preventing permanent deformation. 
>>Axles are crimped in place, eliminating the welding process, while ensuring the rollers cannot break free and fall into the wellbore. 
>>The system's high-quality construction materials improve high-pressure/high-temperature capabilities.
>>Roller Casing Rigid Centralizers are available in sizes 4-1/2" to 20".
>>Any special sizes are available on request.
Roller Casing Rigid Centralizers can also remove wellbore cake and  improve mud replacement efficiency etc.
>>Roller Casing Rigid Centralizers provide superior wear resistance and have been proven to remain functional throughout the life of the well and can aid in casing/tubing retrieval. 
>>Precision-machined inside diameter fits over the casing through the complete API tolerance range, providing excellent rotational performance in mud. 
>>When running casing through open hole, the system's smaller roller-contact area reduces the risk of differential sticking and maintains standoff .
