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

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.
