ASTM A376 TP347H Seamless Stainless Steel Pipe for High Temp & Pressure Industrial Applications
Product Brief

ASTM A376 / ASME SA376 TP347H (UNS S34709) seamless stainless steel pipe, austenitic material stabilized with niobium (Nb) + tantalum (Ta), is designed for high-temperature and high-pressure industrial scenarios. It features excellent creep resistance, anti-intergranular corrosion, and stable mechanical properties at elevated temperatures (≤900℃). Made of seamless process, it has precise dimensions, high pressure-bearing capacity, and is widely used in boilers, heat exchangers, and high-temperature fluid transport systems in petrochemical, power generation and other industries.

Core Product Advantages
  1. High-Temperature Performance: TP347H stabilized with Nb+Ta, excellent creep resistance at high temperature (≤900℃), no deformation or failure after long-term service under high temp & pressure.
  2. Corrosion Resistance: Strong anti-intergranular corrosion and medium corrosion, suitable for harsh industrial environments such as petrochemical and high-temperature fluid transport.
  3. Pressure-Bearing Capacity: Seamless production process, uniform structure, high tensile strength and toughness, strong pressure-bearing capacity, not easy to burst or leak.
  4. Dimensional Precision: Strictly comply with ASTM A376 standard, precise OD/WT tolerance, good interchangeability, easy to assemble with other components.
  5. Durability: Nb+Ta stabilization enhances material stability, service life is 2-3 times that of ordinary stainless steel pipes, reducing maintenance and replacement costs.
  6. Versatility: Widely used in boilers, heat exchangers, petrochemical, power generation and other industries, supporting custom specifications and end treatments.
