High Frequency Welding Fin Tube For Waste Heat Recovery System TP347H Base Pipe
| Attribute | Value |
|---|---|
| Base Tube Material Grade | TP347H |
| Base Tube Material Standard | ASTM A312, ASME SA312 |
| Fin Type | High Frequency Welding |
| Fin Material | Carbon Steel, Stainless Steel, Alloy Steel |
The High Frequency Welding (HFW) Fin Tube is specifically designed for waste heat recovery systems operating in high-temperature, highly corrosive environments with potential dust accumulation. This specialized fin tube utilizes TP347H stainless steel for the base pipe and carbon steel for the fins, offering exceptional durability in demanding applications.
Primary applications include:
- Power station boilers
- Industrial boiler economizers
- Waste heat recovery systems
- High-temperature processing equipment
For environments with significant ash accumulation, studded type fin tubes are recommended as an alternative solution.
TP347H demonstrates excellent oxidation resistance at elevated temperatures, making it suitable for continuous operation at temperatures up to 900°C (1650°F). This material is particularly effective in furnace components and industrial equipment exposed to extreme heat conditions, including incinerators and similar high-temperature processing systems.
