API Standard High Quality Oilfield Sucker Rod Centralizer with competitive price

Product Description

Sucker Rod centralizer is used to connect with the sucker rod, which has a perfect centralizing effect. It solves the problem of the oil well partial abrasion and also plays the scraping wax function. It can greatly extend the tube and rod service life and prolong the period of the pump inspection. It is an ideal partial abrasion prevention product, which is not only increasing oil production but also reducing the cost .

1.Wheel Centralizer

While working ,the wheel rolls inside the tubing,which can protect the sucker rod wiping with tubing pipe.

2.Twist Centralizer

While working,it depends on the friction with the tubing wall to provent friction between sucker rod and tubing.

3.Rod Shaped Centralizer

While working,nylon block touches the tubing inside,which can protect the sucker rod wiping with tubing pipe.

The nylon block will be rotated while it's working,then the rub is evenly. The user can only change the nylon block, not need to replace rod body,which can save fabrication-cost.
