Polymer centralizers are installed on the casing string to ensure trouble-free lowering of the tubing string into the well and centering it relative to the wellbore walls. The centralizer is made according to the dimensions of the casing pipe and the well from a complex-composite polymer material. Its position is fixed by restrictive rings with screw or welding to ensure free rotation of the centralizer on the lowered casing.
