T22 Alloy Steel Seamless Fin Tube 11Cr High Frequency Welding Type Applications
Power Industry
-
Boiler Air Preheaters
-
Recovers heat from 540℃~580℃ flue gas to preheat combustion air (150℃~300℃), boosting boiler efficiency.
-
T22 alloy resists sulfide corrosion; high-frequency welding ensures strong fin-tube bonding for low thermal resistance.
Petrochemical Industry
-
Process Gas Preheaters
-
Preheats reaction gases (up to 600℃) in catalytic processes, withstanding H₂S/CO₂ corrosion and 10~20MPa pressure.
-
Fins stay secure under high-flow conditions, maintaining efficient heat transfer.
Metallurgy Industry
-
Furnace Flue Gas Preheaters
-
Recovers 600℃~700℃ waste heat to preheat combustion air (300℃~450℃) for steelmaking furnaces.
-
Resists dust fouling; compact design fits industrial spaces, reducing energy consumption.
Key Advantages in Preheaters
| Feature | Benefit |
| 540℃~700℃ heat resistance | Sustains high-temperature operation |
| High-frequency welded fins | 2~3x higher heat transfer vs. bare tubes |
| Corrosion/wear resistance | Reduces maintenance in harsh flue gas |

T22 Alloy Steel Seamless Fin Tube 11Cr High Frequency Welding Type Competitive Advantage
-
We have more than 10,000 square meters workshop, including 10 extrusion finning machines, daily extrusion capacity up to 3,000 Meters.
-
The extrusion finning machines are designed and assembled by ourselves and we can offer you finning machines, extrusion muff sleeves and all accessories (extrusion finning disks) etc...
-
DR-extruded bimetallic fin tubes maximum operating temperature: 300 degree. The transfer coefficient remains steady.
-
DR-extruded bimetallic fin tubes have stronger fins than other mechanical fins, like L, LL, KL, and G, so it is much easier to clean.
-
In application of high stress and corrosive condiction, DR-extruded bimetallic fin tubes provides an excellent technical and economical savings in comparsion to a costlier single alloy tube, as the use of costlier material is reduced to the min.
