Import Aluminum Extruded Fin Tube — Buy in wholesale FOB from Supplier in China

Yangzhou Minyang Heat Transfer Technology Co., Ltd. manufactures aluminum extruded fin tubes through a triple-spindle finning process that mechanically bonds aluminum fins to a core tube. The fin stock draws from aluminum alloys 1060, 1050, 1070, 6063, 6061, and 3003, with fin outer diameters from 25 mm to 85 mm, fin thickness from 0.25 mm to 1.0 mm, and fin density of 5 to 12 fins per inch. Tube lengths extend from 300 mm to 18,000 mm. The core tube accepts diverse materials including SA179 carbon steel, SA789 S31803 duplex stainless, SS304 and SS316L austenitic stainless, SA334 low-alloy steel, copper alloys C44300 and C68700, nickel alloys UNS N08800 and UNS N04400, IN825, and titanium. This construction yields a metallurgically bonded fin-to-tube interface with pressure contact achieved through reduction of the aluminum inner diameter during extrusion.

The extrusion process begins with a core tube inserted into an aluminum primary tube. Three multi-disc packs simultaneously extrude the aluminum into helical high fins while compressing the inner diameter onto the core tube surface. This produces a fin with full root contact and no air gap, yielding thermal resistance lower than tension-wound or embedded fin types. The 6063 and 6061 fin alloys offer higher tensile strength for applications with mechanical cleaning or vibration, while 1060, 1050, and 1070 provide maximum thermal conductivity. The 3003 alloy adds manganese for improved corrosion resistance in mildly acidic or salt-laden environments. Base tube selection governs pressure containment: SA179 for standard air-cooled heat exchangers, duplex or super-duplex stainless for chloride-bearing service, and copper-nickel alloys for seawater or brackish water coolers. Fin density selection involves engineering trade-offs: higher fin counts increase surface area but reduce fin efficiency and may clog in dusty or fouling environments.

Primary applications span air-cooled heat exchangers for oil refineries and petrochemical plants, process gas coolers, power plant condensers and boiler air heaters, HVAC dry coolers, and refrigeration condensers. The 18,000 mm maximum length accommodates large-bundle air-cooled heat exchangers with minimal field welds. Buyers include EPC contractors for hydrocarbon processing, power generation OEMs, and industrial refrigeration system builders. For procurement, confirm the design pressure and temperature to select compatible base tube material and wall thickness. Request fin-to-tube contact resistance test data or calculate expected performance against bare-tube equivalents. Lead times, MOQ, and pricing are not stated in the listing and must be confirmed directly with Yangzhou Minyang Heat Transfer Technology Co., Ltd.

Yangzhou Minyang Heat Transfer Technology Co., Ltd. is located at No.1 Zhichen Road in Yizheng, a county-level city under Yangzhou's administration in Jiangsu Province, China. The supplier holds harbor-tier trust status on the platform, with a response rate of 0.00 percent and no recorded average response time. This lack of response data means buyers should expect to follow up proactively via multiple channels and consider engaging a local representative or inspection agent in the Yangzhou area for time-sensitive negotiations. The company's address in Yizheng places it within the Yangzhou industrial corridor, a region with established metalworking and heat exchanger component manufacturing clusters.

The supplier profile presents Yangzhou Minyang as a specialized manufacturer of extruded fin tubes with technical knowledge of alloy selection, base tube compatibility, and application engineering for air-cooled heat exchangers and HVAC systems. No information is provided about year of establishment, factory floor space, workforce size, annual turnover, export destinations served, or quality management certifications such as ISO 9001 or ASME U/U2 stamps. The listing does not name specific clients, reference projects, or whether the company holds API 660 or other industry-specific certifications relevant to petrochemical heat exchanger supply. Buyers should request a company brochure, audited financials for credit assessment, and evidence of previous export shipments including packing lists and bills of lading before committing to large orders.
