Ultra-High Pressure Resistance Tungsten Carbide Piston Sleeve with Low Friction Coefficient and Superior Corrosion Resistance

Product Overview
The Tungsten Carbide Piston Sleeve is a high-performance component engineered for extreme operating conditions, widely used in high-pressure plunger pumps, hydraulic systems, and precision injection molding equipment. Manufactured from high-purity tungsten carbide (hard alloy) through precision sintering and grinding processes, it combines ultra-high hardness, exceptional wear resistance, and excellent corrosion resistance. Capable of maintaining long-term stable performance under high pressure, high speed, and in abrasive media, it significantly enhances equipment service life and operational efficiency.

Core Advantages

• Exceptional Wear Resistance, Extended Service Life
  With a hardness exceeding HRA 90, the tungsten carbide material offers wear resistance more than 20 times greater than traditional chrome steel tubes. It maintains an extremely low wear rate even in unlubricated or abrasive media environments, drastically reducing replacement frequency and maintenance costs.
• Ultra-High Pressure Resistance, Reliable Stability
  Featuring a compressive strength over 3000 MPa, it withstands extreme system pressures and frequent impact loads, preventing deformation or fatigue cracking. This ensures long-term, stable operation of equipment under demanding conditions.
• Low Friction Coefficient, Energy Efficient
  The surface undergoes nano-level polishing, achieving an ultra-smooth finish of Ra ≤ 0.1 μm. This effectively reduces friction against sealing elements, improves energy efficiency, and minimizes power loss.
• Superior Corrosion Resistance, Handles Complex Media
  Resistant to acidic, alkaline, and high-salinity media, it is suitable for corrosive environments such as chemical processing and marine engineering, preventing performance degradation due to corrosion.

Technical Parameters
