We are offering Stailnless steel finned tubes in various size and
as per customer specifications. The fin and the base tube material
will be SS **4, SS **6. Finned tubes are mainly used in
Pharmaceutical industries, Food processing industries.Compared with
plain finned tube, the serrated finned tubes can obviously increase
the thermal efficiency
