1. The wear-resistant sleeve is made of reinforced polytetrafluoroethylene sintered as a whole, which does not fall off or fall off quickly during use in the well;
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. It has high wear resistance;
4. 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;
5. 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%;
6. The structure is simple and easy to install and use on site.
