Editor’s Pick: Wheeled Rod Guide Couplings

The rolling action of the wheels inside the tubing walls during stoking reduces friction and wear caused by sucker rods slapping or rubbing the tubing.

Wheeled Rod Guide couplings from Oilfield Improvements (Broken Arrow, OK) reduce wear and prolong the life of sucker rods and tubing by centralizing the sucker rod string in the tubing. The rolling action of the wheels inside the tubing walls during stoking reduces friction and wear caused by sucker rods slapping or rubbing the tubing. According to the company, with proper use of the Wheeled Rod Guide couplings and effective chemical treatment programs, several operators have extended by an average of four times the operating periods between having to pull and service wells because of sucker rod or tubing wear.

Wheel angles are designed to centralize the sucker rod string in the tubing. The wheels are set vertically, and at 45 degree angles to each other, along the axis of the coupling body. This design assures the centralizing effect wherever the Wheeled Rod Guide couplings replace the regular couplings.
