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.
