Cemented Carbide Valve Core and Valve Seat for Oil & Gas Industry
Evolution and Structure of Valve Balls:
Hard alloy ball valves, evolved from traditional plug valves, feature a closure element in the form of a sphere. Opening and closing are achieved as the sphere rotates around the valve stem axis. Valve balls play a crucial role in cutting off, distributing, and altering the flow direction of the medium within pipelines. Specially designed ball valves can also regulate fluid flow.
Application in the Oil and Gas Industry:
Precision-manufactured tungsten carbide valve seat pairs are extensively utilized in petroleum drilling, deep-sea oil drilling, and pump valve balls and seats. These components are critical in oil pump systems.
Working Environment and Requirements:
The petroleum drilling industry operates in harsh conditions, involving wells with sand, heavy oil wells, and high-pressure anti-sand oil wells, where the medium contains corrosive elements such as water, gas, wax, and sand. Pump valves demand superior sealing, wear resistance, and corrosion resistance from their ball and seat components.
Advantages of Tungsten carbide Valve Balls:
Tungsten carbide valve balls exhibit outstanding properties, including high density, wear resistance, and corrosion resistance, making them particularly suitable for petroleum extraction and transportation. In lifting oil drilling pump systems, their high hardness, density, strength, stable chemical properties, exceptional resistance to bending, and impact toughness surpass other material choices.
In the process of petroleum extraction and transportation, the failure modes of pump valve balls include wear, corrosion, fatigue cracks, and fragmentation. The hard alloy tungsten steel valve seat and valve head, with their high hardness, density, strength, stable chemical properties, exceptional resistance to bending, and impact toughness, significantly improve drilling efficiency, extend tool lifespan, and reduce operational costs.
Zhuzhou Sanxin cemented carbide products mainly include nozzles, bushings & sleeves, sealing rings, molds, inserts, mill rollers, and other customized components.
Cemented carbide is a composite hard alloy material that consists of refractory metal bonded together by a metallic binder through powder metallurgy.
