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
2. Boilers & Superheaters
3. Petrochemical & Refining
4. Food & Pharmaceutical Processing
5. Marine & Desalination
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?
2. Why U-bend instead of straight tubes?
3. How to prevent stress corrosion cracking (SCC)?
4. What’s the max operating temperature?
5. How to inspect U-bend tubes?
