Copper tube for the production of solar heat absorbers in level-wound coils and straight lengths
In the production of absorbers for solar collectors, seamless copper tubes are welded using copper or aluminium sheets.
In the ultrasound welding process of solar absorbers in particular, a very clean tube surface is required to ensure the high quality of the welded seam between the copper tube and the absorber sheet.
With solarclean manufacturing processes, such a clean surface is required that when manufacturing the absorber, depending on the production process, at least one cleaning stage or labour-intensive pre-treatment of the components to be connected can be dispensed with.
