ASME SA213 TP304L U-Bend Boiler Tube – Applications & Key Features

SA213 TP304L is a low-carbon austenitic stainless steel (18% Cr, 8% Ni, low C) used in U-bend boiler tubes for high-corrosion resistance and flexibility in heat exchangers.

 

Primary Applications
1. Heat Exchangers & Condensers

  • Shell & tube heat exchangers (U-bends allow thermal expansion).
  • Surface condensers in power plants (resists steam/condensate corrosion).

2. Boilers & Superheaters

  • Recovery boilers (handles flue gas condensates).
  • Low-pressure steam boilers (where chloride stress corrosion is a concern).

3. Petrochemical & Refining

  • Reboilers, feedwater heaters (resists acidic/alkaline conditions).
  • Refinery heat recovery systems (exhaust gas applications).

4. Food & Pharmaceutical Processing

  • Sanitary heat exchangers (non-reactive, easy to clean).

5. Marine & Desalination

  • Desalination plant tubing (resists saltwater pitting/crevice corrosion).

 

Why Use SA213 TP304L U-Bend Tubes?

✔ Excellent corrosion resistance (vs. carbon steel in acidic/chloride environments).
✔ Low carbon content (0.03% max) – prevents sensitization & intergranular corrosion.
✔ Good weldability – no post-weld heat treatment required.
✔ High ductility – U-bends withstand thermal expansion stresses.
✔ Oxidation resistance up to ~800°C (1472°F).

 

Comparison with Other Grades

Grade Key Features Best For
TP304L Low carbon, general corrosion resistance Most heat exchangers, food/pharma
TP316L Added Mo (2-3%), better chloride resistance Marine, desalination, harsh chemicals
TP321 Ti-stabilized, resists sensitization High-temp exhausts, aircraft
TP347 Nb-stabilized, superior creep resistance Superheaters, high-pressure steam

 

Common FAQs
1. Can TP304L handle high-pressure steam?

  • Yes, but for >500°C (932°F), TP321/TP347 is preferred due to better creep strength.

2. Why U-bend instead of straight tubes?

  • Absorbs thermal expansion (reduces stress on tube sheets).
  • Compact design (saves space in heat exchangers).

3. How to prevent stress corrosion cracking (SCC)?

  • Avoid chloride exposure >60°C (140°F).
  • Use TP316L if chlorides are present.

4. What’s the max operating temperature?

  • Continuous: ~800°C (1472°F) (oxidizing environments).
  • For pressure service: ~425°C (797°F) per ASME limits.

5. How to inspect U-bend tubes?

  • Dye penetrant (PT) for surface cracks.
  • Radiography (RT) for internal defects.
  • Need Custom Specifications
  • Bend radius: Standard (1.5D–3D) or custom.
  • Finishing: Pickling/passivation for enhanced corrosion resistance.
  • Certification: EN 10204 3.1 / MTC with PMI test reports.
