Heat Exchanger Tubes

Heat Exchanger Tubes – ASTM A213 / A269 / B163 Manufacturer in India

Inox Steel India – Seamless & Welded Heat Exchanger Tubes for High-Performance Thermal Systems

Inox Steel India is one of the leading manufacturers, stockists, and exporters of Heat Exchanger Tubes produced as per ASTM A213, ASTM A269, and ASTM B163.

These tubes are engineered for high-efficiency heat transfer, corrosion resistance, and long-term reliability in industrial thermal systems working with steam, chemicals, refrigerants, and high-temperature fluids.

Our Heat Exchanger Tubes are used across:

  • Refinery heat exchangers
  • Power plant condensers
  • Chemical processing heaters
  • Pharmaceutical thermal systems
  • Food processing evaporators
  • HVAC & refrigeration coils
  • Petrochemical coolers
  • Desalination plants

Every tube is manufactured with precise tolerances, smooth internal surface, and superior mechanical stability to ensure optimal thermal conductivity and long lifecycle.

We supply straight tubes, U-bend tubes, finned tubes, and custom coil tubes, produced using advanced cold-drawing mills, bright annealing lines, and automated NDT inspection systems.

Understanding Heat Exchanger Tube Standards

Heat exchanger tubes differ from boiler tubes or process tubing — their priority is thermal efficiency, corrosion resistance, and dimensional precision.

ASTM A213 – Alloy Steel & Stainless Steel Heat Exchanger Tubes

Used for:

  • High-temperature steam heat exchangers
  • Petrochemical heaters
  • Refinery exchangers

Grades include:

  • T11, T22
  • TP304 / 304L
  • TP316 / 316L
  • TP321

Advantages:

  • Smooth ID for efficient heat transfer
  • High strength at elevated temperature
  • Excellent weldability in U-bent exchangers

ASTM A269 – Stainless Steel Heat Exchanger Tubes

Used in:

  • Food processing
  • Pharma heat exchangers
  • Chemical heaters
  • High-purity steam lines

Common grades:

  • TP304 / 304L
  • TP316 / 316L
  • TP321

Advantages:

  • Extremely close OD/WT tolerances
  • Bright annealed surface
  • Excellent corrosion resistance

ASTM B163 – Nickel Alloy Heat Exchanger Tubes

Used for:

  • High-temperature corrosive media
  • Chloride-rich environments
  • Acidic heating & cooling systems

Common grades:

  • Inconel 600 / 625
  • Incoloy 800 / 825
  • Monel 400
  • Hastelloy C22 / C276

Advantages:

  • Extreme corrosion resistance
  • Exceptional oxidation resistance
  • High strength at elevated temperatures

Manufacturing Process of Heat Exchanger Tubes

1. Solid Billet → Hot Piercing → Hollow Shell

2. Cold Drawn / Cold Rolled Processing

3. Bright Annealing

4. Straightening & Cutting

5. U-Bending (For Shell & Tube Exchangers)

6. Non-Destructive Testing
