HIGH FREQUENCY WELDED FINNED TUBES
The main uses for high frequency welded finned tubes are in the heat recovery associated with boilers for power generation and in furnace applications for the various processing industry.
We supply the highest quality welded finned tubing to any part of the world for use in oil refineries, petrochemical plants, power generating stations, fertilizer and gas production plants. The newly designed manufacturing facility, with our high frequency resistance welding machines, enables us to perform large scale projects in reduced times.
The steel fin (solid or serrated) is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces a homogeneous, clean and continuous fin-to tube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.
The welding process enables the combination of any grades for studs and tube: carbon, alloy, stainless steels and high nickel alloys. Alloy steel pipes are stress-relieved after studding, according to the relevant specifications for the class and grade of steel used.
Our high frequency welding finning machines are capable of handling tube diameters from 21 mm o/d to 273 mm o/d and tube lengths of up to 26 meters. Fin sizes range from 6 mm to 38 mm high and from 0.8 mm to 3 mm thick.
