Product Description

Tungsten carbide oil nozzles are nozzles made from tungsten carbide–cobalt (WC-Co) cemented carbide. They are used to spray oil at specific flow rates, pressures, and spray angles. Due to their exceptional wear resistance, they are 5-10 times more durable than quenched steel nozzles. Their service life can reach 8,000–15,000 hours, and they can operate reliably even under extreme conditions, such as very low temperatures (-196 °C) and high temperatures (up to 850 °C).

Features of Tungsten Carbide Oil Nozzles

  • Exceptional Wear and Abrasion Resistance: Tungsten carbide oil nozzles feature extremely high hardness, typically HRA 90 or higher, which is significantly higher than that of most conventional metals. This outstanding hardness gives the nozzles superior abrasion resistance, allowing them to handle fluids containing abrasive particles such as sand, mineral powders, and catalysts. As a result, their service life can be tens to hundreds of times longer than ordinary steel nozzles.
  • Outstanding Erosion Resistance: In high-velocity fluid environments, tungsten carbide nozzles demonstrate excellent erosion resistance. They can withstand fluid flow velocities exceeding 150 m/s, making them ideal for applications involving high-pressure or high-speed fluid transmission, such as oil and gas production and industrial spraying systems..
  • Excellent Corrosion Resistance: Tungsten carbide oil nozzles offer good resistance to corrosive media commonly found in industrial processes. They can effectively resist corrosion from acidic gases and liquids such as H₂S and CO₂, which are frequently present in oil and gas extraction environments. This ensures stable performance even in chemically aggressive conditions.
  • Superior Mechanical Strength and Toughness: Tungsten carbide oil nozzles have a high elastic modulus and excellent bending strength, enabling them to maintain structural stability under high loads and high-pressure working conditions. This combination of strength and toughness ensures reliable performance even in demanding industrial environments.
  • High Dimensional Stability and Precision: Tungsten carbide has a low coefficient of thermal expansion, ensuring excellent dimensional stability even under fluctuating temperatures and pressures. This helps maintain the accuracy of the nozzle’s internal channel, flow rate, and spray angle over long periods of operation.
