Product Description
We have independently developed and completed two leading finned tube production processes, namely, integral rolling and laser welding, so that the materials available for finned tubes cover almost all common metal materials, such as copper, aluminum, and their alloys, stainless steel, titanium, etc. The integral rolling ensures that the fins and the header are extruded into shape, without contact thermal resistance; Laser welding can ensure 100% welding rate between fins and base tube. No need to add solder for welding. The weld is smooth and full, and the heat exchange between fins and base tube is smooth. Since the first product was exported in 2008, Fidelity's constant pursuit of product quality and responsible attitude towards customers have won customers' favor!
