HFW FIN TUBE
Hfw Fin Tube is the short name of High-frequency welded spiral finned tube,widely used in petrochemical, machinery, metallurgy, rubber, printing and dyeing, food, power plants, passenger cars, drying and other industries for heating and cooling. It is the most ideal heat exchange component used on the convection sections of cracking furnaces and reformers, air preheaters, economizers, heat exchangers, crystallizers, radiators and hot pipe technology. In particular, GRD steel finned radiators are widely used in office buildings, residential buildings, hotels, factories and other industrial and civil construction industries, it has good heating effect and is the replacement of traditional cast iron, plate type radiators.

APPLICATION
The conditions for the use of finned tubes are: the temperature of the flue gas must not be lower than 380 ° C; heating can generally only by firing gas. When heavy oil is required to be as fuel, the fin spacing should not be less than 2 FPI. Furnaces for burning oil or high viscosity residual oil shall not use finned tubes.
