In power generation, petrochemicals, and HVAC industries, the efficient transfer of heat is paramount. This process relies entirely on the quality and integrity of the tubes used in boilers and heat exchangers. Choosing the right material ensures maximum thermal efficiency and minimum operational downtime. Key Demands on Heat Exchanger Tubes The tubes in a heat exchanger are subjected to two main stresses simultaneously: Thermal Stress: Extreme temperature differentials between the two fluids. Corrosion: Attack from corrosive fluids on both the inside and outside of the tube wall. Therefore, the ideal tube material must combine high thermal conductivity, exceptional high-temperature strength, and resistance to scaling and corrosion. Material Selection: Matching the Environment Standard Service: Carbon steel (e.g., ASTM A179) is often used for non-corrosive, low-temperature water/steam service. Corrosive Service: Stainless steel (especially SS 316L) is the standard for chemical processing and mildly acidic/alkaline fluids. High Temperature/Pressure: Alloy steel (e.g., P11, P22) or Nickel alloys (e.g., Inconel 600) are necessary for superheaters and aggressive furnace environments. Seawater/Chloride: Titanium or high-performance Duplex steel is often specified to prevent pitting and crevice corrosion.
