Project Description

Product Introduction: Ultra-Pure Ferritic Corrosion-Resistant Heat Exchange Tubes

Our ultra-pure ferritic corrosion-resistant heat exchange tubes are specifically designed for applications requiring exceptional resistance to chloride-induced corrosion and outstanding mechanical properties. Manufactured using ultra-pure ferritic stainless steel grades, these tubes offer superior performance in challenging environments such as coastal power plants, seawater desalination facilities, and industries with high chloride content. By leveraging advanced metallurgy and precision manufacturing techniques, we provide heat exchange tubing solutions that deliver reliability, efficiency, and longevity.

Product Description:

Ultra-pure ferritic corrosion-resistant heat exchange tubes are made from ultra-pure ferritic stainless steel materials known for their exceptional corrosion resistance and mechanical strength. The unique microstructure and chemical composition of these materials confer remarkable resistance to:

  • Chloride Ion Stress Corrosion Cracking
  • Pitting Corrosion
  • Crevice Corrosion
  • Intergranular Corrosion

These properties make our tubes ideal for use in aggressive environments where standard materials may fail. In developed countries like the United States, ultra-pure ferritic heat exchange tubes have been widely adopted in coastal power plant condensers, seawater desalination, salt production, and chemical industries with high levels of chloride ions.

Performance Characteristics:

  1. Superior Strength and Rigidity:
    • High Mechanical Properties:
      • The strength and stiffness of ultra-pure ferritic stainless steel tubes are significantly higher than those of titanium tubes and cupronickel tubes.
    • Durability:
      • Enhanced mechanical properties contribute to longer service life and resistance to deformation under operational stresses.
  2. Exceptional Wear Resistance:
    • Wear Performance in Sandy Seawater:
      • Among the four commonly used condenser tube materials, the wear resistance ranks from highest to lowest as follows:
        • Ultra-Pure Ferritic Stainless Steel Tube (S44660)
        • Titanium Tube (TA2)
        • Cupronickel Tubes (BFe30-1-1 and BFe10-1-1)
    • Reduced Maintenance:
      • Superior wear resistance minimizes erosion and abrasion, leading to decreased maintenance costs.
  3. Outstanding Corrosion Resistance:
    • Seawater Applications:
      • Our ultra-pure ferritic stainless steel welded tubes exhibit much higher corrosion resistance in seawater compared to cupronickel tubes and standard stainless steel tubes.
    • Equivalent to Titanium Tubes:
      • The corrosion resistance of our tubes is essentially comparable to that of titanium tubes, providing a cost-effective alternative without compromising performance.
  4. Efficient Heat Transfer:
    • Heat Exchange Efficiency:
      • The overall heat transfer efficiency of condensers using ultra-pure ferritic stainless steel tubes is virtually the same as those using titanium tubes and is not lower than that of copper tubes.
    • Thermal Conductivity:
      • Although the thermal conductivity coefficient is slightly lower than that of titanium tubes, it has a negligible impact on the total heat transfer efficiency during operation.
    • Operational Performance:
      • Ensures optimal thermal performance in heat exchange applications, contributing to energy efficiency.

Available Grades:

We offer the following ultra-pure ferritic stainless steel grades:

  • S445J1
