        Application characteristics of lined tubing: tubing lining is a kind of material based on macromolecule polymer. It has excellent wear resistance, impact resistance, excellent environmental stress cracking resistance, good self-lubrication, adhesion resistance, excellent chemical stability and other advantages.The friction coefficient between sucker rod and tubing is reduced by adding lining to common tubing.
        Because the inner surface of liner pipe is smoother than that of common new steel pipe, the friction force between rod coupling and liner pipe is much smaller than that between rod coupling and common tubing pipe, which is equivalent to the friction between ice and ice, thus reducing the load of smooth rod and having a good energy-saving effect.
