TP347H Stainless Steel Pipe 1.5in SCH160 ASTM A213 Stainless Steel Tubing

Product Specification

TP347H High Pressure Pipe 1.5in SCH160, ASTM A213, Ultra-High Temp, Boiler Lines

TP347H Stainless Steel High-Pressure Pipes (1.5" SCH160)​ by ​Jiangsu China Steel Union Industrial Co., Ltd​ are engineered for ultra-high-temperature applications in power plant boilers, superheaters, and steam reforming units. Compliant with ​ASTM A213, these stabilized austenitic stainless steel pipes contain niobium (Nb) to prevent carbide precipitation and ensure exceptional creep resistance at temperatures up to ​700°C. The 1.5" SCH160 dimensions (OD: 48.3mm, Wall Thickness: 7.14mm) withstand pressures exceeding ​3,000 psi, making them ideal for critical steam lines exposed to thermal cycling and oxidation. Seamless manufacturing and solution annealing guarantee microstructural stability in coal-fired, gas-fired, and biomass energy systems.

3. Advantages of Importing Our Product

1. ​Ultra-High Temp Performance: Nb stabilization prevents sensitization and ensures creep resistance in 700°C+ steam environments.
2. ​Cost Efficiency: 20% lower pricing than European/U.S. suppliers, leveraging Jiangsu’s integrated production from alloy melting to precision tube forming.
3. ​Fast Delivery: 10,000-ton annual capacity; 14-day lead time for ASTM A213-certified orders from Shanghai or Rotterdam hubs.
4. ​Zero-Defect Assurance: 100% PMI testing, ultrasonic inspection (UT), and IGC (Intergranular Corrosion) reports per ASTM A262.
5. ​Custom Solutions: Induction bending, flanged ends, and bespoke thermal coatings (Al-Si or Inconel 625) for retrofit projects.

4. Key Applications

• ​Power Generation: Superheater and reheater tubes in coal/gas-fired boilers and combined-cycle plants.
• ​Petrochemicals: Steam methane reformer (SMR) coils, hydrocracker charge heaters, and ethylene furnace tubes.
• ​Waste-to-Energy: High-pressure steam lines in biomass incinerators and syngas processing units.
• ​Nuclear Plants: Auxiliary steam systems and non-reactor heat exchangers.
• ​Industrial Heating: Process heaters, thermal oil circuits, and high-temperature fluidized bed reactors.

Jiangsu China Steel Union Industrial Co., Ltd​ delivers ASTM A213-certified TP347H stainless steel pipes that redefine reliability in ultra-high-temperature energy systems, offering unmatched durability and compliance for global power, petrochemical, and heavy industries.
