ASTM 316L Seamless Tube and Aluminum Composite Fin Tube

ASTM 316L Seamless Tube and Aluminum Composite Fin Tube

Making of two tubes, the outer tube is rolled onto the core tube in order to provide for a tight bond and good thermal contact between the two tubes.

For composite finned tube, we need to pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging.

Overall rolling fin is smooth and has no burr, so it is easy to clean. It is easy to make the fin surface wet and cooled with water when makes it cold during heating air-conditioning engineering. In the situation with drying, heating and other heat exchanging, its surface is handles by anodizing, which with beautiful color and luster, and can effectively prevent surface corrosion.
