The Bimetal composite Extruded finned tube is the most widely used finned tube for heat exchange with air. The manufacturing process of Bimetal composite Extruded finned tube is: firstly, a certain thickness of aluminum tube is tightly set on the base tube, and then the aluminum tube is rolled by rolling machine to remove the spiral fins, thus forming a tightly structured bimetal composite rolled finned tube.

The advantages of the Bimetal composite Extruded finned tube: small contact heat resistance, long life, smooth fin surface, complete isolation of the base tube from the heat exchange medium, not easy to scale, easy to clean, and can maintain good heat transfer performance for a long time. The material of the base tube can be chosen from carbon steel, stainless steel, titanium, purple copper, etc.

Bimetal composite extruded finned tubes are widely used in air conditioning, air-cooling, power stations, petroleum, chemical industry, etc. and various equipment for heat exchange with air.
