welded spiral fin tubes ( fin tubes ), 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 welded helical (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.



Available tubes /pipe material for fin tubes:
fin material: carbon steel, corrosion-resistant steel, stainless steel, alloy steel, copper
welding finned forms: real teeth, opened teeth(serrated fin tubes)
