High Frequency Welding Fin PIPE, Stainless Steel ASTM A312 TP347H For HRSG Sysytem
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.
1. Material Specification
Base Pipe Material: ASTM A312 TP347H Stainless Stee
less and Welded Austenitic St
ainless Steel Pipes)
Grade: TP347H – a high-carbon version of 347 stainless steel with excellent creep strength at elevated temperatures.
2. Chemical Composition
Chemical Composition (ASTM A312 TP347H Stainless Steel)
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.
5. Applications in HRSG Systems
Heat Recovery Steam Generators:
Captures waste heat from gas turbine exhaust.
Preheats feedwater 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.
6. Advantages in HRSG Systems
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.
