Anti-corrosion Sucker Rod Centralizer Made in China

  Anti-corrosion Sucker Rod Centralizer Made in China

1. Structure and work principle

1) Structure

It composed of coulping, centralizer sleeve and sub.

2) Work 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.

2. Tech parameter

1) hardness of centralizer steel: HB220-257;

2) compressive strength of centralizer sleeve:60-90Mpa;

3) medium temperature: 0-200°C.

3. Advantages

Sucker rod centralizer is a new developed tool to prevent eccentric wear. Simple structure, convenient operation, long service life and low cost.
