Twist on sucker rod centralizer /SUCKER ROD GUIDE eliminates or greatly reduce down-hole problems with Snap-On and Twist-On Rod Guides. With a coefficient of friction when wet lower than metal, overall pumping efficiency is increased while costly metal-to-metal contact between the rods and tubing is minimized.
Twist On sucker rod guides contain no metal clip insert. Tests, however, indicate an excellent holding strength due to design and materials. The Twist-On style rod guide can easily be installed with a pipe wrench, and withstands temperatures up to 200oF.
The product is made by moulding strengthened, plasticized, hard wearing PA66(nylon 66) material at a time and processing it through heat aging, the product is clipped into the sucker rod through the diagonal slot and fits closely with the flange of the sucker rod after revolving at a certain angle, and thus the position is fixed and rod is centralized.
