The stainless steel welded pipe aluminum fin is a double fin heat transfer finned tube. Unlike the alloy finned tube. The outstanding feature is that the advantages of different strengthening methods can be integrated on the same fin to achieve better overall performance. The bimetal rolled composite finned tube is composed of a base pipe and an outer fin. The base pipe is usually a carbon steel pipe, a stainless steel pipe or a copper pipe. The aluminum tube is placed outside. The aluminum tube is then extruded into the fins using a special rolling mill. At the same time, a thin layer is formed outside the base pipe to tightly wrap the base pipe. The production methods of composite finned tubes are mainly welding and rolling. The main performance requirements of fin-enhanced heat transfer, composite fins and composite finned tubes are described in detail.
