EN 10217-7 1.4301 AL Extruded Finned Tube
Yuhong can produce EN 10217-7 1.4301 Extruded Type Finned Tube
Yuhong Group has been operating stainless steel/duplex/nickel seamless tubes and finned tubes for more than 20 years, with annual sales of more than 80,000 tons of stainless steel/duplex/nickel seamless tubes. Our clients have covered more than 45 countries. Our stainless steel seamless pipes are widely used in mining, energy, petrochemical, chemical, food mills, paper mills, gas and fluid industries and more.
Extruded bimetal finned tube
The finned tube is composed of iron-aluminum or copper-aluminum tube rolled fins, with a tight feather shape, small thermal resistance, good heat transfer performance, high strength, small flow loss, strong corrosion resistance, not easy to deform, cold resistance and corrosion resistance sex. chaud. Long service life under conditions, etc.
The fins are smooth and burr-free as a whole and easy to clean. When the air-conditioning project is heating and cooling, it is easy to make the surface of the fins wet and cold. In the case of heat exchange such as drying and heating, the surface is anodized and the color is beautiful, which can effectively prevent surface corrosion.The fins are smooth and burr-free as a whole and easy to clean.

In the case of heat exchange such as drying and heating, the surface is anodized and the color is beautiful, which can effectively prevent surface corrosion.
Rolled finned tubes are integrally rolled from aluminum tubes, and have the characteristics of no contact thermal resistance, high strength, thermal shock and mechanical shock resistance, good thermal performance, and a considerable expansion heat transfer surface. Such finned tube heat exchangers are located at the front of the tubes or around the plates.
The extruded finned tube is a bimetallic tube whose outer surface of aluminum is processed into fins by cold plastic deformation.
