The welded tube can be flat oval, rectangle, round, and other shapes according to customers’ requirements. A flat oval welded tube is mainly used as a radiator tube, the radiator is the most important component of the cooling module, which consists of the radiator core and plastic tanks with all requisite connections and fastening elements. The radiator core is usually made of aluminum. Besides traditional aluminum flat oval welded tubes, we also offer welded B-type tubes and surface dimpled tubes. CHAL working together with our partners is still developing new tubes with enhanced characteristics to face new challenges of cooling devices.

With walls as thin as 0.26 mm, we design radiator tubes with superior strength, performance, and cost-efficiency at a very compact size and drastically reduced weight. All our aluminum radiator tubes are HF-seam welded and made in our state-of-the-art facilities in Montgomery, Alabama, and Dortmund, Germany. Many of our tubes have been used by some of the world’s most respected engine manufacturers, from racing to complex industrial applications.
Profiles from 13 mm to 52 mm in tube height
Multiple-chambered, dimpled, and end-free tube technologies
Metal strip gauges as thin as 0.26 mm
A wide array of aluminum alloys available
TUBE TECHNOLOGIES.
Dimpled
For high-performance radiators and heater cores to increase the turbulence of the fluid and heat transfer by breaking the boundary layers inside the tubes.
Multiple-chamber
Reduced core thickness for tighter space constraints, superior performance with less area, and increased mechanical stability for high-pressure applications.
End-free
For standard radiator headers, tubes can be manufactured with the form eliminated from the tube ends, offering no tube-to-header joint interruption and a superior leak-free brazing process.
