Tips of tungsten carbide stem seat
Seat is often used in oil pumping, thermal recovery wells, sand wells, coal and other fields, its working conditions are very bad. However, tungsten carbide seat has excellent performance, so it can well adapted to the environment:
1. A good physical properties: high hardness, surface drilling fluid for shock resistance, resistance to erosion, high wear resistance, and its abrasion resistance is 15 to 20 times higher than the best high-speed steel.
2. Stable chemical properties: high temperature, anti-oxidation, anti variety of media corrosion (acid, alkali, salt, multi-gas, etc.) .
