API Sucker rod Centralizer for oilfield
1. Descriptions of centralizer
Our company produces short circuit 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 .
2.Working principle
Using the pumping unit head moving forward and down to drive the centralizer on the pumping rod , which ensures the friction position not fixed in the same point. Thus, the wearing time of the centralizer is extended, meanwhile, the centralizing and scraping wax function is played
3.Application
Used for partial-wear tubing and sucker rod of the well, especially for middle and above the rod eccentric wear of pump.
