Welded flat-oval aluminum tubes

Welded flat-oval tubes

 

Welded flat-oval pipes for general technical use in the manufacture of mechanical engineering products.

Designed to circulate coolant or air:

- in the production of car radiators;

- in charge air coolers.

Tubes are made of a multilayer tape made of aluminum alloys with additional anti-corrosion characteristics.

The tubes are supplied in corrugated boxes made of seven-layer cardboard. To exclude the movement of tubes, shock absorbers are used to compensate for the void in the height, length and width of the box. The length of the tubes is set in the customer's specifications.
