1. The wear-resistant sleeve is made of reinforced polytetrafluoroethylene and sintered as a whole, which does not fall off or fall off during use in the well
Quick;
2. The surface friction coefficient of the wear-resistant sleeve is extremely low, and it has strong self-lubricating performance, greatly reducing the wear on the sleeve;
3. The wear-resistant sleeve itself has high wear resistance;
4. The anti-wear sleeve can rotate freely between the fixed ring and the inner sleeve, thereby reducing the distance between the anti-wear sleeve and the sleeve
Friction resistance improves the service life of the anti wear sleeve;
5. The wear-resistant sleeve is made of reinforced polytetrafluoroethylene material, which has a temperature resistance of over 200 degrees and good acid and alkali resistance
Can;
6. It has good wear reduction and torque reduction performance, with a decrease in wear resistance of about 20% and a decrease in torque of about 30%;
7. The anti-wear sleeve has a long service life, with a service life of ≥ 500 hours;
8. The structure is simple and easy to install and use on site. Simply fix this product directly onto the drill pipe.
