Welded aluminium rectangular tubes
Sapa offers welded aluminium rectangular tubes to cover a wide range of heat exchanger functions.
Rectangular welded tubes are available in a variety of aluminium combinations and thicknesses to ensure the applications’ mechanical properties, corrosion resistance and thermal performance are met in a cost effective manner. Tubes are offered predominantly in clad aluminium, which offers the ability to combine a low melting point brazing alloy with a high strength core, and if required, corrosion resistant inner cladding.
New higher strength corrosion resistance long life alloys are in regular production, offering cost and weight reductions opportunities. Core material clad with brazing alloys on both inner and outer surfaces are available for charge air and oil cooler applications, allowing internal turbulators to be brazed to the tube wall, creating an uninterrupted heat flow medium from coolant to air.
