ASTM A213 TP304L Stainless Steel U Bend Tube For Heat Exchanger

ASTM A213 TP304L is a specification for seamless and welded austenitic stainless steel tubes, designed for high-temperature and corrosion-resistant environments. The "TP304L" grade is a low-carbon version of 304 stainless steel, providing enhanced weldability and resistance to intergranular corrosion.

The U Bend Tubes are widely used in heat exchangers, condensers, boilers, and other applications where heat transfer efficiency is critical.

Key Features:

  • Material Composition:

    • Chromium (18–20%): Provides excellent corrosion and oxidation resistance.
    • Nickel (8–12%): Enhances toughness and ductility.
    • Low Carbon Content: Prevents carbide precipitation during welding, reducing the risk of intergranular corrosion.

  • Corrosion Resistance:

    • Superior resistance to general corrosion, pitting, and crevice corrosion in chloride-rich environments.
    • Suitable for use in chemical processing, marine, and petrochemical industries.

  • High-Temperature Strength:

    • Can withstand elevated temperatures without significant deformation or loss of mechanical properties.

  • Dimensional Precision:

    • Manufactured with strict tolerances to ensure proper fit in heat exchangers and condensers.

Applications:

  • Heat Exchangers
  • Condensers
  • Power Generation Plants
  • Chemical Processing Equipment
  • Oil and Gas Industry
  • Desalination Plants

Advantages of U Bend Tubes:

  • Compact Design: The U-bend configuration allows for efficient use of space in heat exchangers.
  • Improved Heat Transfer: Maximizes contact area for heat exchange between fluids.
  • Durability: Resistant to cracking, corrosion, and thermal stress.
