API standard Sucker Rod Centralizer
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.

working principle:
It connect with Sucker Rod, the centralizer casing OD is larger than the Sucker Rod Coupling OD in order to centralizer rod. Centralizer casing has high strength wear resistant, so when contact with oil tube, makes the centralizer body wearing and reduces oil tube wearing so as to anti-wear (centralizer casing temperature resistant: 260°C, material: self-lubricating Ni-p plating material). The steel surface adopt Ni-p plating (the anti-corrosion technology) makes the centralizer has the ability of anti-wear and anti-corrosion. And it also suitable for the worse corrosion well condition.
