Stainless Steel Condenser Tube and Boiler Tube

Technical Insights: Manufacturing and Standards

Our stainless steel tubing products are precision-manufactured to ensure reliability and compliance with the highest industry standards, such as:

• ASTM A249: For welded tubes intended for high-temperature applications.
• ASTM A213: For seamless and welded austenitic stainless steel tubing.
• ASTM A554: For ornamental tubing with mechanical properties.

Advanced manufacturing processes such as laser welding and cold drawing ensure precise dimensions and superior surface finishes, making our tubing ideal for even the most demanding applications.

Types of Stainless Steel Condenser Tube

1. Austenitic 

Austenitic stainless steels are the most commonly used type of stainless steel for condenser tubes due to their excellent corrosion resistance, high ductility, and ability to withstand high temperatures.

Common Grades:

• 304/304L:
  • Widely used for general applications.
  • Features excellent corrosion resistance and high weldability.
  • Ideal for non-extreme environments.
• 316/316L:
  • Enhanced with molybdenum for superior resistance to pitting and crevice corrosion.
  • Suitable for marine environments and applications exposed to chlorides or chemicals.
• 321:
  • Stabilized with titanium to resist intergranular corrosion.
  • Designed for high-temperature applications.

Applications:

• Heat exchangers in HVAC systems.
• Food and beverage processing equipment.
• Desalination plants.

2. Ferritic

Ferritic stainless steels are known for their magnetic properties and moderate corrosion resistance. These tubes are typically used when lower cost and resistance to scaling in high temperatures are important.

Common Grades:

• 409:
  • Economical option with moderate resistance to corrosion.
  • Often used in automotive exhaust systems and heat exchangers.
• 439:
  • Improved corrosion resistance compared to 409.
  • Suitable for applications in oxidizing environments.

Applications:

• Automotive heat exchangers.
• Industrial cooling systems.

3. Duplex 

Duplex stainless steels are a blend of austenitic and ferritic grades, offering a combination of strength, corrosion resistance, and cost-effectiveness.

Common Grades:

• 2205 Duplex:
  • High resistance to stress corrosion cracking.
  • Twice as strong as standard austenitic grades.
  • Excellent for use in brackish or seawater environments.
• 2507 Super Duplex:
  • Enhanced corrosion resistance and mechanical properties.
  • Ideal for extremely harsh environments, such as offshore oil and gas operations.

Applications:

• Oil and gas condensers.
• Chemical processing equipment.
• Power plants.

4. Martensitic Stainless Steel Condenser Tube

Martensitic stainless steels are characterized by their high strength and moderate corrosion resistance. These tubes are typically used in applications requiring mechanical properties over corrosion resistance.

Common Grades:

• 410:
  • High strength with good corrosion resistance.
  • Often used in lower-stress environments.
• 420:
  • Offers higher hardness after heat treatment.
  • Suitable for applications requiring wear resistance.

Applications:

• Turbine condensers.
• Industrial machinery.

5. High-Performance Alloys

For industries requiring extreme resistance to corrosion and temperature, high-performance alloys based on stainless steel are used.

Common Grades:

• 904L:
  • Super-austenitic stainless steel with high molybdenum content.
  • Exceptional resistance to chlorides and sulfuric acid.
• Alloy 254 SMO:
  • Combines strength and corrosion resistance for extreme environments.

Applications:

• Chemical processing.
• Marine and desalination applications.
