Abstract

Verfahren zur Herstellung eines Verbundrohres (13), welches zumindest ein Kernrohr (2), eine Dämmstoffschicht (8) und ein Mantelrohr (11) umfasst, wobei in einem Dämmstoffausformungsbereich (21), welcher sich um das Kernrohr (2) erstreckt, ein schäumbares Dämmmaterial in einem Dämmmaterialeinbringungsbereich mittels Pistole eingebracht wird, das Dämmmaterial sich in einem Dämmmaterialausformungsbereich zu der Dämmstoffschicht (8) ausformt und die Dämmstoffschicht (8) in einem Dämmschichtformbereich geformt wird und das Mantelrohr (11) um die geformte Dämmstoffschicht (8) aufgebracht wird, wobei das Verbundrohr im Dämmschichtformbereich erwärmt wird, wobei der Dämmmaterialeinbringungsbereich und der Dämmschichtformbereich auf einen definierten Temperaturbereich erwärmt oder gekühlt wird.
