Our high-efficiency finned tubes are manufactured in carbon steel, stainless steel, and alloy steel materials, offering a wide range of base tube diameters and fin heights. Available in various fin types—such as L-foot, G-foot, and embedded—and configurations including solid or segmented fins, these tubes deliver superior heat transfer performance, making them ideal for boilers, heat exchangers, and air coolers. Custom material combinations for tubes and fins, along with specialized surface treatments, can be provided to meet specific application requirements.

Our finned tubes are manufactured using advanced high-frequency welding and precision rolling technology, featuring automated fin forming with consistent pitch control (±0.2mm), in-line tension testing for fin bond strength verification, computer-controlled tube straightening systems, and non-destructive eddy current testing for quality assurance. The manufacturing process ensures strict dimensional tolerances including fin height (±0.1mm) and tube outer diameter (±0.05mm), guaranteeing optimal heat transfer performance and structural reliability.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
