Import Extruded Fin Tube — Buy in Bulk from Supplier in China

The Extruded fin tube from Jiangsu Reliance Thermal Equipment Co., Ltd. is a bimetallic heat transfer component with aluminum fins integrally extruded onto a steel or copper base tube. The fins are formed in a continuous process, ensuring a metallurgical bond without solder or adhesives. Base tube diameters range from 15.88 mm to 50.8 mm, with fin heights up to 16 mm and fin densities of 7 to 11.5 fins per inch, consistent with standard industrial extrusion practices.

The aluminum fins are typically made from A1100 alloy, which offers good thermal conductivity and moderate corrosion resistance. The base tube material can vary depending on application, including carbon steel, stainless steel, or copper alloys. This construction provides durability in aggressive environments such as chemical processing or marine HVAC systems. The extrusion process eliminates gaps between fin and tube, reducing thermal resistance compared to wrapped or bonded alternatives.

This product is commonly used in condensers, air-cooled heat exchangers, and industrial chillers where high thermal efficiency and compact design are critical. Buyers include manufacturers of power generation equipment, HVAC system integrators, and chemical plant engineers. Packaging is typically in wooden crates or steel pallets with corrosion-inhibiting wraps. Trade terms are negotiable but typically FOB Jiangyin Port, with lead times of 4 to 6 weeks after order confirmation. MOQ is not specified but can be discussed per project scale.

Jiangsu Reliance Thermal Equipment Co., Ltd. is located at 19 Shashan Road, Huashi Town, Jiangyin, Jiangsu, China.
