Cemented Carbide valve balls, due to their excellent properties such as high hardness, wear resistance, corrosion resistance, and high-temperature stability, have wide applications in petroleum, chemical, power, and marine industries.
I. Oil and Gas Industry
1.1 High-Pressure Oil and Gas Pipeline Valves: Cemented carbide valve balls are used in high-pressure oil and gas transmission systems, withstanding extreme pressures and corrosive media (such as sand-containing, heavy oil, and acidic gases). Their bidirectional sealing design ensures zero leakage in high-pressure differential environments such as deep-sea drilling.
1.2 Oil Pump Check Valve: As a key component of oil pumps, the cemented carbide valve ball and valve seat form a check valve, controlling the unidirectional flow of oil when it is extracted from the formation. Its high hardness and wear resistance resist abrasion from sand particles, extending tool life; its corrosion resistance adapts to complex media such as water, gas, and wax, significantly improving drilling efficiency and reducing maintenance costs.
1.3 Special Operating Conditions Adaptation
Sand-bearing wells and heavy oil wells: The valve ball has an extremely high surface finish, matching the mirror-finish valve seat, reducing the risk of particle jamming.
High-temperature and high-pressure environments: The valve ball, manufactured using a vacuum sintering process, can operate stably within a temperature range of -196℃ to 450℃, adapting to cryogenic or high-temperature pipeline systems.
II. Chemical and Pharmaceutical Industries
2.1 Corrosive Media Valves: Cemented carbide valve balls have excellent corrosion resistance to acids, alkalis, salts, and other chemicals, used in valve systems handling toxic or highly corrosive fluids (such as hydrogen peroxide, methane, ethylene, etc.) to prevent leakage and environmental pollution.
2.2 Sanitary Valves: In the food and beverage processing industry, valve balls must meet pollution-free sealing requirements to ensure that the production process complies with food safety standards.
III. Power and Energy Sector
3.1 Steam Turbine Valves: The high-temperature resistance of cemented carbide valve balls makes them a key component in steam turbine valves, ensuring stable system operation under high temperature and pressure.
3.2 Nuclear Power Plant Valves: In the nuclear energy field, valve balls must withstand radiation and extreme temperature changes. Their high density and impact resistance ensure reliable opening and closing of valves in emergency situations.
IV. Marine Engineering and Shipbuilding
4.1 Offshore Platform Valves: Cemented carbide valve balls are adapted to salt spray and high-pressure seawater environments, used in offshore drilling platform valves to reduce maintenance needs due to corrosion and extend equipment lifespan.
4.2 Marine Valve Systems: In marine oil and gas pipelines, valve balls withstand ship swaying and media impact. Their wear resistance ensures long-term sealing performance.
V. Other Industrial Sector
5.1 Water Treatment and Environmental Protection Equipment: In wastewater treatment plants and seawater desalination equipment, valve balls resist particle abrasion and corrosion, improving equipment durability.
5.2 Aerospace Precision Control: Cemented carbide valve balls are used in precision control valves to withstand extreme temperature and vibration conditions, such as rocket fuel delivery systems.
5.3 Metallurgical and Mining Machinery: In high-pressure media delivery pipelines, valve balls withstand high pressure differentials and high-speed fluid impacts to ensure the continuity of metallurgical processes.
