WHEELED ROD GUIDE
Sucker-rod centralizers also may be called paraffin scrapers or rod guides. They keep the rods and couplings away from the tubing to decrease wear. However, special mechanical paraffin scrapers have been developed
to also aid in keeping paraffin off the tubing and most of the sucker-rod length.
Rod centralizers with full-bore-fluted centralizers should be placed on or between the pump-handling pony rod, the sinker bars used above the pump, and the first two sucker rods above the sinker bars. Rod centralizers in these locations help stabilize the pump and valve rod and prevent valve-rod bending or breakage. When a tubing anchor is not used, rod centralizers will reduce tubing wear because of tubing helical buckling on the upstroke. Rod centralizers also may be used in crooked holes in which there are areas of concentrated tubing wear.
.
Guide Couplings should be installed:
1.On the first two or three rods above the bottom hole pump.
2.Intermittently throughout the rod string where wear is indicated on rods or tubing.
3. Where known hole deviation occurs.
4.On the first two or three rods below the stuffing box
