G4 Cemented Carbide Wear Parts Tungsten Carbide Valve Sealing Seat
Features of tungsten carbide stem seat
- Matched with a unique product called tungsten carbide hollow ball,which is often used in oil and nature gas industry,If you are interested in our hollow spheres, please contact with us.
- The TC Balls are manufactured as per Anti-Friction Bearing Manufacturer Association (AFMBA) standards.
- Standard sized balls in 6% Cobalt material are readily available in stock with us.
- These Tungsten Carbide Seats are used for various Oil Field Equipment and Oilfield Valves such as Conventional Gas Lift Valves, Wireline Retrivable (WLR) Injection Pressure Operated (IPO) Gas Lift Valves etc.
Tips of tungsten carbide stem seat
-We can supply tungsten carbide ball and valve seat with high precision.
-With high corrosion and wear resistance, and high strength and
temperature resistant, our valve balls (tungsten carbide pellets)
and seats are exported to many countries.
-Made of tungsten carbide, Tungsten Carbide round Balls/cemented carbide ball/hard alloy
ball is also called hard alloy balls. It is used for places
requiring extreme hardness and resistance to wear and abrasive,
hard shocks and impacts.
-Tungsten carbide saddles can be used for special valves, flow
meters, recirculating balls bearing screws, liner bearing and balls
for ball point pens. They are also used for mining, as pivots and
points of compotation. What's more, they are also used for
measurements or calibrations of holes and measurement checking
devices.
