Description
welded spiral finned tubes ( fin tubes )( TECHNIFIN TYPE WO“, WOS“,
LFS“, )
manufacturing capabilities for helical solid finned tubes ( fin
tubes ) and serrated finned tube:
High-frequency welding finned tube production range
fin material: carbon steel, corrosion-resistant steel, stainless
steel, alloy steel
welding finned forms: real teeth, opened teeth(serrated fin
tubes)
Frequency welding spiral fin tube is a highly efficient heat
transfer components. Its heat transfer area of ​​the optical
tube several times or more, enhanced heat transfer, reducing the
flow resistance, reducing the metal consumption, thus improving the
economy and operational reliability of the heat transfer equipment.
At present, high frequency welding spiral fin tubes has been widely
and has been widely used in a variety of chemical, electric power,
metallurgy, petrochemical, boiler, building materials, textile,
environmental protection, dry, medical field.
