High Frequency Helical welded solid fin tubes ( finned tubes )
or Serrated Finned tubes (finned tubes)
We produce Welded Finned pipes and Tubes in many different
diameters and fin configurations and metal combinations to meet
your heat transfer needs.
welded spiral fin tubes ( finned tubes )( TECHNIFIN TYPE WO“, WOS“,
LFS“, )
manufacturing capabilities for helical solid fin tubes ( finned
tubes ) and serrated finned tube:
High-frequency welding finned tubes (pipes) 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 tubes (pipes) is a highly efficient
heat transfer components. Its heat transfer area of ​​the
optical tubes (pipes) 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.
