Factory Supply Sucker rod Nylon centralizer/ plastic centralizer 

Sucker rod centralizer

Snap-on Sucker rod centralizer is used in pumping well, it's a tool which can set upright the sucker rod, and protect the sucker rod wiping with tubing pipe.

Application:

Rod up and down inside the tubing activity, due to the elastic deformation of sucker rod, rod and oil tube wall is easy to produce friction, sucker rod break off easily, sucker rod centralizer has strong flexibility, it contact with the pipe wall, can reduce the friction of rod and tube, enhance the production life of pumping unit

Structure:

Snap-on Sucker rod centralizer is composed of collar, centering sleeve and nipple. 

Working theory: 

It connects 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.
