Condenser Tubes – ASTM B111 / B338 Manufacturer in India

Inox Steel India – Seamless & Welded Condenser Tubes for Power Plants, Refineries & Industrial Cooling Systems

Inox Steel India is a leading manufacturer, stockholder, and exporter of Condenser Tubes manufactured in accordance with ASTM B111 (Copper Alloy Tubes) and ASTM B338 (Titanium Tubes). These condenser tubes are engineered for high thermal conductivity, corrosion resistance, erosion resistance, and long lifecycle in cooling water, seawater, brine, and industrial fluid transfer systems.

We supply condenser tubes for:

  • Thermal power plant condensers
  • Desalination plant condensers
  • Refinery & petrochemical surface condensers
  • Marine coolers
  • HVAC & refrigeration systems
  • District cooling plants
  • Industrial process chillers

Condenser tubes play a critical role in transferring heat from steam to the cooling water circuit. Their performance directly affects turbine efficiency, energy output, and operational cost. Hence, tube material selection — Copper Alloys (ASTM B111) or Titanium (ASTM B338) — is essential depending on water quality, temperature, scaling tendency, and chloride levels.

Understanding Condenser Tube Standards

🔹 ASTM B111 – Copper & Copper-Nickel AlloyASTM B111 covers seamless copper-nickel and copper alloy tubes with excellent thermal conductivity and seawater resistance.

Common grades:

  • C70600 (90/10 Cu-Ni) – Best for seawater
  • C71500 (70/30 Cu-Ni) – Higher strength, high chloride service
  • Admiralty Brass (C44300) – High thermal conductivity
  • Aluminium Brass (C68700) – High erosion resistance

🔹 ASTM B338 – Titanium Condenser TubesASTM B338 covers seamless and welded titanium tubes used in harsh seawater, brine, and corrosive environments.

Common grades:

  • Titanium Grade 2 – Excellent seawater resistance
  • Titanium Grade 5 – High strength
  • Titanium Grade 9 / Grade 12 – Enhanced corrosion resistance

Manufacturing Process of Condenser Tubes

Manufacturing Steps:

  1. Piercing & Hollow Formation: Seamless tubes are hot-extruded to ensure tube integrity.
  2. Cold Drawing / Cold Rolling: Refines wall thickness, OD, and internal surface smoothness.
  3. Straightening & Heat Treatment: Annealing, Stress relieving, and Bright annealing for titanium.
  4. Surface Cleaning: Decontamination essential for heat-transfer efficiency.
  5. NDT Testing: Eddy current, ultrasonic, hydrotest, air-under-water test.
  6. Finishing: Straight lengths, U-bent form, or Cut-to-length.

Why Industries Prefer ASTM B111 & B338 Tubes

  • High Thermal Conductivity: Copper alloys deliver superior heat-transfer efficiency.
  • Superior Corrosion Resistance: Titanium offers unmatched resistance to chlorides, brine & seawater.
  • High Erosion & Cavitation Resistance: Perfect for high-flow condenser applications.
  • Long Service Life: Titanium tubes last 20–40 years even in aggressive water.
  • Low Fouling Surface: Reduces scaling, enhancing overall plant efficiency.
  • Global Preference: Preferred by EPC contractors & OEMs for Power Plants + Desalination.

Engineering Notes (For Condenser Designers)

  • Material Selection: Use ASTM B111 for high thermal conductivity and low-to-medium chlorides. Use Titanium (ASTM B338) for high chlorides (> 500 ppm), marine/offshore, and zero corrosion tolerance.
  • Velocity: Copper alloys are best at moderate flow; Titanium withstands higher velocity with excellent erosion resistance.
  • Tube Expansion: Titanium requires controlled torque expansion; Cu-Ni expands easily but needs careful pressure control.
  • Efficiency vs. Corrosion: Copper = best heat transfer; Titanium = best corrosion resistance. Select based on water quality.
