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

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

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