| High Light | ASTM A312 TP321H Finned Tubes ，Seamless HFW Finned Tubes ，High-Temperature Stability Finned Tubes | ||
ASTM A312 TP321H seamless stainless steel high-frequency welded (HFW) finned tubes are made of titanium-stabilized high-carbon austenitic stainless steel as the base material, combined with the high-efficiency HFW finning process.
They are mainly applied in heat transfer systems operating under high temperatures ranging from 427°C to 816°C, corrosive conditions, and thermal cycling environments. Particularly suitable for power plant boilers, petrochemical heating/waste heat recovery, chemical heat exchange, and special industrial heating scenarios, these tubes balance mechanical strength, intergranular corrosion resistance, and heat transfer efficiency.
Typical Application Scenarios
1.Power Industry
Coal-fired/gas-fired power plants: Superheaters, reheaters, economizers of boilers, and flue gas waste heat recovery units.
Nuclear power plants: Heat transfer tubes in secondary loop steam generators.
2. Petrochemical and Oil Refining Industry
Tubular heaters: Finned tubes in convection and radiant sections.
Fluid Catalytic Cracking (FCC): Finned tubes in regenerators and waste heat boilers.
Hydrocracking/hydrofining: Feed heaters for reactors.
3. Chemical and Coal Chemical Industry
Ammonia/urea production plants: Finned tubes in reformers and waste heat boilers.
Sulfuric acid/nitric acid production: Heat exchangers.
Coal chemical gasifiers: Radiant waste heat boilers.
Base Tube Chemical Composition
| Carbon% | Manganese% | Phosphorus% | Sulfur% | Silicon% | Nickel% | Chromium% | Nitrogen% |
|---|---|---|---|---|---|---|---|
| 0.08 | 2.00 | 0.045 | 0.030 | 1.00 | 9.0-12.0 | 17.0-19.0 | 0.10 |
The titanium content shall be not less than five times the carbon content and not more than 0.70%.
| Tensile Strength, min | Yield Strength, min | Elongation in 2" or 50mm, min |
|---|---|---|
| 75ksi (515 MPa) | 30ksi (205 MPa) | Longitudinal:35%; Transverse:25% |
