ASTM A312 TP347H Serrated Fin Tube Application
1. Power Generation:
- Boilers: Used in superheaters and reheaters where high temperatures and pressures are prevalent.
- Heat Recovery Steam Generators (HRSG): Efficient heat transfer is crucial in HRSGs, and serrated fin tubes enhance this process.
2. Petrochemical Industry:
- Furnaces and Heaters: The tubes are used in environments with high temperatures and corrosive gases.
- Catalytic Reforming Units: These units operate at high temperatures and require materials that can withstand thermal stress and corrosion.
3. Refineries:
- Crude Oil Heaters: The tubes are used in heaters that preheat crude oil before distillation.
- Hydrogenation Units: These units require materials that can resist hydrogen embrittlement and high temperatures.
4. Chemical Processing:
- High-Temperature Reactors: Used in reactors where chemical reactions occur at elevated temperatures.
- Heat Exchangers: Serrated fin tubes improve the efficiency of heat exchangers in chemical plants.
5. Waste Heat Recovery:
- Recuperators and Regenerators: These systems recover waste heat from industrial processes, and the enhanced heat transfer of serrated fin tubes is beneficial.
6. Nuclear Power Plants:
- Steam Generators: The tubes are used in steam generators where high thermal efficiency and corrosion resistance are required.
ASTM A312 TP347H Serrated Fin Tube Strength
