API Composite Centralizer Casing with Metal Rings/Thermoplastic Casing Centralizer 

spiral blades composite centralizer with metal rings

Composite Casing Centraliser is the ultimate in down-hole centralisation, offering field proven lower friction coefficients leading to superior drag and rotational torque reduction. High abrasion resistant proprietary engineered polymer ensures maximum stand-off at TD. Robust enough to meet the challenges of today’s most demanding wells.
