The ASTM A213 TP347H seamless pipe is a niobium-stabilized austenitic stainless steel, UNS S34709, with a composition of 17-20% chromium, 9-13% nickel, and niobium at a minimum of 8 times the carbon content. This listing provides diameters from 6 to 580 mm and wall thicknesses from 1 to 30 mm, designed for high-temperature service in power generation, petrochemical, and refinery applications.
TP347H is selected for its superior creep resistance and oxidation resistance at elevated temperatures, making it ideal for superheater and reheater tubes in boilers. The niobium stabilization prevents chromium carbide precipitation, ensuring long-term corrosion resistance in cyclic thermal conditions. Typical industry applications include heat exchangers and components exposed to fluctuating pressures and temperatures.
Buyers in power plants and petrochemical sectors source TP347H for its ability to withstand extreme conditions without compromising mechanical integrity. The seamless construction guarantees reliability in critical systems. Confirm the delivery condition, dimensional tolerances, and test certificates such as EN 10204-3.1 MTC before finalizing an order. Trade terms include FOB, CFR, or CIF, with payment via TT or L/C.

Prior to ordering, verify the pipe’s chemical composition, particularly the niobium and carbon content, as these directly impact its high-temperature performance. Request the EN 10204-3.1 mill test certificate to ensure the material meets ASTM A213 TP347H specifications. Check that the delivery condition aligns with your project’s needs, whether cold-drawn, hot-rolled, or heat-expanded.
Discuss logistics early to confirm the port of loading, Incoterms, and container specifications. Lead times for TP347H are typically 15 to 20 days, but this can extend for larger orders. Clarify payment terms (TT or L/C) and any pre-shipment inspection requirements to avoid delays in customs or production schedules.
For quality control, arrange for third-party inspections to verify dimensions, surface finish, and material composition against your specifications. Request a hydrostatic test report if the pipes will be used in high-pressure systems. Ensure all documentation, including certificates of origin and compliance, is accurate and complete for smooth import processing.
