Information you should know about Serrated fin tube
The specifications of serrated fin tubes mainly include diameter, length, fin spacing and height.
Diameter: Common specifications are 22mm, 25mm, 32mm, 44mm, 60mm, etc.
Length: Common specifications are 1m, 1.2m, 1.5m, etc.
Fin spacing and height: Common fin spacings are 3-5mm, 5-8mm, etc., and common fin heights are 5-10mm, 10-15mm, etc.
Choosing the right diameter and length can meet the requirements of heat exchange area and heat exchange efficiency, while the influence of fin spacing and height is the problem of heat dissipation area and fluid resistance. The smaller the fin spacing, the larger the heat dissipation area, but the fluid resistance will also increase; the higher the fin height, the larger the heat dissipation area, but too high a fin height will increase the fluid resistance. Therefore, it is necessary to make a reasonable choice according to actual needs.
The specifications and materials of the Serrated finned tube include carbon steel, corrosion-resistant steel (ND steel), stainless steel, and alloy steel.
The Serrated finned tube is a product completed by high-frequency welding. Its material selection is very flexible and can meet the needs of different application scenarios. The selection of this finned tube includes but is not limited to:
Carbon steel: It has good plasticity and strength and is suitable for general industrial applications.

Corrosion-resistant steel (ND steel): It has excellent corrosion resistance and is suitable for some special environments, such as chemical industry, marine engineering, etc.
Stainless steel: It has excellent corrosion resistance and is suitable for food processing, medical equipment and other fields that require high hygiene.
Alloy steel: By adding alloy elements to improve strength and corrosion resistance, it is suitable for extreme environments such as high temperature and high pressure.
The design of the finned tube increases the heat dissipation area, so that heat can be quickly transferred to the air, thereby improving the heat dissipation efficiency. This design is widely used in boiler water-cooled walls, economizers, air preheaters and other equipment. It is also suitable for industrial waste heat recovery and other special purposes.
