Spiral Vane Roller Composite Centralizer

>>Spiral Vane Roller Composite Centralizer consists of rigid body, on which machined spiral blades.
>>There are made of advanced composite that has a low coefficient of friction and is heat resistant and highly durable, fully heat treated rollers fixed on every spiral blades. 
>>Because of rigid body and rolling friction between the rollers and inside of well or casing.
>>The capability of the roller Centralizer is better than others of all. Roller/Wheeled composite centralizers are mainly used for big high Roller, high deviated wells and horizontal wells, to centre casings.
>>Roller Composite Centralizers can also remove wellbore cake and  improve mud replacement efficiency etc.
>>Roller Composite 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 .
>>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 Composite Centralizers are available in sizes 4-1/2" to 20".
>>Any special sizes are available on request.
