Blackening Sucker Rod Centralizer
1. Structure and work principle
1) Structure
It is 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
| type | Sucker rod(screw type) | OD mm | Total length mm | Centralizer length mm |
| KFZ-19 rotation | Φ19(3/4'') | Φ58 | 265-270 | 91 |
| KFZ-22 | Φ22(7/8'') | Φ58 | 265-270 | 91 |
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.
4. Applying rules
1) a little eccentric wear well: one set for 3 rods.
2) Eccentric wear well: one set for 2 rods.
3) More eccentric wear well: one set for one rod.
4) Seriously eccentric wear well (inflection point): one set for one rod, and install one nylon centralizer between sucker rods.
