ASTM A213 T9, T11, T22, T9, 304/L Alloy Tubing

• Seamless alloy and stainless steel tubing manufactured to ASTM A213 / ASME SA-213 for high-temperature and boiler applications. Available in heat-resistant alloy grades and common austenitic stainless grades suitable for steam, heat exchangers, furnace, and process piping.

• Key available grades: T9, T11, T22, T91, T92 (high-temperature alloy/Cr–Mo variants) and stainless grades TP304/L, 316L, 317L, TP321/H. Material selection supports elevated-temperature strength, creep resistance and corrosion resistance where required.

• Typical dimensions:

  • Outside diameter (OD): 1/8" up to 16" (approx. 3.2 mm to 406 mm)
  • Wall thickness: wide range available — specify required schedule or exact wall thickness when requesting a quote
  • Lengths: standard 10 ft, 20 ft, 40 ft or cut-to-length per project requirements

• Product form and quality:

  • Seamless construction for superior strength and performance under pressure and high temperature
  • Supplied as straight lengths; custom cutting, chamfering and special end preparations available on request
  • Mill Test Certificates (MTC) available; optional third-party inspection and additional NDT (e.g., UT, PMI) can be arranged per buyer requirements

• Typical applications:

  • Boiler tubes, superheater and reheater headers
  • Heat exchangers and condensers
  • Power generation, petrochemical and refinery piping
  • Chemical processing, fertilizers and sugar mills
  • Instrumentation, hydraulic lines and other critical process systems

• Commercial details:

  • Customizable to project specifications — grade, OD, wall thickness and length
  • Contact supplier with RFQ including grade, OD, wall thickness, length, quantity and any required certificates or inspections

If you need an exact quote or specification sheet (chemical/mechanical), provide the required grade, dimensions, quantity and destination so we can confirm availability, lead time and compliance documentation.
