Tungsten Carbide Wear-Resistant Bushings for the Petrochemical Industry

Tungsten carbide wear-resistant bushings are widely used in the petrochemical industry. Due to the working environment of the petrochemical industry, which often involves high temperatures, high pressures, corrosive media, and high-frequency mechanical movements, tungsten carbide (cemented carbide) bushings are well-suited for such scenarios due to their excellent performance. The following are specific applications and advantages in the petrochemical industry:

• Wear Resistance and Corrosion Resistance: Petrochemical equipment such as pumps, valves, and compressors are often exposed to corrosive liquids or gases (such as acids, alkalis, and salts). The high hardness of tungsten carbide (up to HRA 89-93) and excellent corrosion resistance can effectively resist wear and chemical erosion, extending the service life of the bushings.
• High-Temperature Stability: Petrochemical processes often involve high-temperature environments. Tungsten carbide bushings have good high-temperature strength and stability, making them suitable for maintaining performance under high-temperature and high-pressure conditions.
• Typical Applications:
  • Centrifugal Pumps and Agitation Equipment: Used for the support and sealing of pump shafts, reducing wear caused by high-speed rotation or vibration. For example, tungsten carbide bushings can be used for shaft protection in multi-stage pumps, reducing maintenance frequency.
  • Valves and Seals: In petrochemical pipeline systems, tungsten carbide bushings serve as precision sealing components, capable of withstanding high-frequency sliding and pressure, ensuring reliable sealing.
  • Drilling and Oil Production Equipment: In oil drilling or oil production machinery, tungsten carbide bushings are used as wear-resistant guide components to cope with high loads and friction under complex working conditions.
• Design Advantages: Tungsten carbide bushings can meet the high-precision requirements of petrochemical equipment through precision machining (such as tolerance control within ±0.002mm). At the same time, their interference fit design facilitates installation and replacement, reducing equipment maintenance costs.
