H/F Fin Tube
High frequency welded finned tube extend heat transfer surface that provides maximum efficency in heat exchange paalications from exhaust hot gas to a contained liquid process.
Both solid and serrated fin tube is used for Heat recovery steam generator, Petrochemical, Boiler plants, Economizer, Gas cooler and Heat exchangers in a wide range of applications.
Solid finned tube is recommentded for contaminated gas steams where oil, coal, wood or other high fouling fuels are used.
Serrated finned tube is primarily used in clean steams.
