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.
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;
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 .
