Tungsten Carbide Valve Gate - China

Tungsten Carbide Valve Gate

high performance valve gate

Valve Gate: The core parts of flat gate valves used in the petrochemical industry require high pressure, wear resistance, corrosion prevention against H2S and CO2, especially wellhead and Christmas tree valves have higher requirements.

Tungsten carbide is one of the most important raw materials for cemented carbide.

It's a black hexagonal crystal with metallic luster, chemical stability, hardness and diamond similarity, and it's also a good conductor of electricity and heat.

In tungsten carbide, carbon atoms are intercalated into the gap of the tungsten metal lattice without destroying the crystal lattice of the original metal, thereby forming a gap solid solution, and thus the tungsten carbide is also called an interstitial compound (or an intercalation compound).

Tungsten carbide is suitable for machining at high temperatures-- it can make cutting tools, structural materials for kiln, jet engines, gas turbines, nozzles, etc.

The hardness of cobalt-based carbonized tungsten alloy powder or nickel-based carbonized tungsten alloy powder and chromium-based carbonized tungsten alloy powder sprayed by HVOF tungsten carbide coating can reach 850 degrees of high temperature of HV1200 - Therefore, the valve parts are resistant to abrasive, corrosion, high temperature and oxidation.

The process exceeds the processes of manual surfacing, chrome plating, carburizing, quenching and tempering, etc., so that the production efficiency can be increased by more than 2 times, the production cost can be reduced by more than 50%, and the service life can be extended by several tens of times.
