The bimetallic ribbed tubes are intended for manufacture of air heaters, air oil coolers (ДЦ, ОДЦ, etc.), industrial radiators, air-cooling units (АВО, АВГ, АВЗ), economizers and others.
The use of two metals in the product at the same time provides it with the required stiffness (support pipe) and efficient heat transfer (aluminum ribs). Cold or hot-deformed solid Steel 20 is used for a supporting pipe, aluminum is used for the ribbing.
