It is recommended that centralizers be used on the rods for reduction of rod string and oil well tubing wear. The centralizers can be fixed; they can be installed directly on the rod body by pressure die casting method. The rotating centralizers are located between the locks on the rod body and can rotate on the same. Apart from ensuring wear protection, centralizers prevent deposits formation inside oil well tubing and increase the time between well overhauls.
