Cemented Tungsten Carbide Sleeves Bushings For Submersible Oil Field
Cemented carbide bushings sleeves are mechanical parts with high wear resistance, strength, and corrosion resistance manufactured through powder pressing, sintering, and precision grinding. These components are widely used in petroleum machinery, coal mining, chemical sealing, and pump valve production.
Applications
Tungsten carbide sleeves serve as protective components with versatile applications. In valve systems, they are installed in valve stem caps to reduce leakage and improve sealing. In bearing applications, they minimize wear between bearings and shaft seats, preventing gap expansion.
These high-strength components withstand prolonged loads and offer excellent chemical stability. They resist alkalis, alcohols, ethers, hydrocarbons, acids, oils, detergents, and water (including seawater). Being odorless, non-toxic, and rust-proof, they are ideal for submerged oil pumps, slurry pumps, water pumps, and centrifugal pumps in petrochemical industries.
