Rigid polymer centralizer with spiral blades NPKF-TsZhPP is made of polymer composite material, which significantly reduces friction force under torsional and axial loads, which in turn improves production efficiency, helping to transfer power to the tool, and not to overcome friction force. The centralizer is installed on a casing pipe or a well screen between two retaining rings.
