ASTM A312 Austenitic Stainless Steel TP347H HFW Solid Fin Tube For HRSG System

High-Frequency Welding (HFW) finned pipes made from ASTM A312 TP347H stainless steel are specifically designed for Heat Recovery Steam Generators (HRSG). HRSG systems are critical components in combined-cycle power plants, capturing waste heat from exhaust gases to generate steam for energy efficiency. The use of TP347H stainless steel ensures excellent resistance to high temperatures, corrosion, and oxidation.

• Base Pipe Material: ASTM A312 TP347H Stainless Steel (Seamless and Welded Austenitic Stainless Steel Pipes)
• Grade: TP347H - a high-carbon version of 347 stainless steel with excellent creep strength at elevated temperatures.

• High-Temperature Performance: TP347H stainless steel has excellent creep resistance and oxidation resistance, making it ideal for HRSG systems operating at elevated temperatures.
• High Efficiency: The finned design significantly increases the heat transfer surface area, enhancing the efficiency of waste heat recovery.
• Durability: The welding process creates strong mechanical bonding between the fins and the pipe, ensuring long service life even under thermal cycling and vibration.
• Corrosion Resistance: TP347H resists oxidation and corrosion in high-temperature and aggressive environments, such as exhaust gases from turbines.

• Heat Recovery Steam Generators: Captures waste heat from gas turbine exhaust and generates steam for combined-cycle power plants.
• Economizers: Preheats feedwater to improve boiler efficiency.
• Superheaters: Ensures steam reaches the desired temperature for turbines.
• Evaporators: Transfers heat to generate steam from water.

• Enhanced Heat Transfer: The finned pipe increases the thermal exchange surface, improving the efficiency of waste heat recovery.
• Energy Savings: Captures and reuses waste heat, reducing fuel consumption and lowering operational costs.
• Long Service Life: Resistant to corrosion, oxidation, and thermal fatigue, ensuring durability under continuous operation.
• Compact Design: Finned pipes allow for a smaller, more efficient heat exchanger layout in HRSG systems.
