Astm A312 Tp347h Steel Pipe
This is a niobium-stabilized austenitic stainless steel pipe in grade ASTM A312 TP347H, supplied by Zhengzhou Huitong Pipe Fittings in Henan, China. The material composition is 18Cr-10Ni with niobium stabilization, designed for service temperatures up to 900°C. The pipe is available in seamless or welded execution, with sizes ranging from 1/8 inch to 56 inches in diameter and wall thicknesses from Schedule 5S to XXS. It meets ASTM A312 standards for pressure and temperature-critical applications.
The TP347H grade offers superior creep resistance and oxidation resistance compared to standard 304 or 316 stainless steels, making it ideal for high-temperature environments in oil refineries, petrochemical plants, and power generation facilities. The niobium addition stabilizes carbon, preventing intergranular corrosion and maintaining mechanical properties at elevated temperatures. Typical industry applications include heat exchangers, superheaters, and boilers where thermal stability is critical.
This product is sourced from major mills in China and is suitable for global export markets. Buyers typically use it in industrial pipelines, chemical processing, and structural applications requiring high integrity under thermal stress. The pipe is packed in bundles with steel strips or wooden cases for protection during transit. Confirm surface finish, end connections, and test certificates with the supplier before ordering.

Sourcing Astm A312 Tp347h Steel Pipe from Zhengzhou Huitong Pipe Fittings - China Import Guide
Before ordering, verify the pipe’s heat number, mill test certificates, and third-party inspection reports. Confirm the exact grade (TP347H) and whether the pipes are seamless or welded, as this affects performance in high-temperature applications. Request documentation for niobium content and stabilization to ensure compliance with ASTM A312.
Discuss logistics details such as packaging, labeling, and shipping methods. TP347H pipes are typically packed in bundles with steel strips or wooden cases, but custom packaging may be required for air or sea freight. Clarify Incoterms (e.g., FOB, CFR, or CIF) and port of loading, as Zhengzhou is inland and may require transport to a major port like Shanghai or Tianjin.
For quality assurance, specify inspection requirements such as visual, dimensional, and non-destructive testing (NDT). Request certificates for pressure rating, temperature limits, and corrosion resistance. If the application involves extreme conditions, consider third-party inspection at the mill or prior to shipment. Always confirm the supplier’s ability to provide test reports in English for customs and compliance purposes.
