Abstract

Såkalte varmeisolerte dobbeltrør (5,6) som har et varmeisolasjonssjikt (15) av polyuretan-hårdskummateriale, kan fremstilles med bedre isolasjonsvirkning og uten varme-/kuldebroer ved at rørene (5,6) før oppskummingen i det mellomliggende mellomrom (11) innrettes adskilt fra hverandre, for derved å eliminere gjennom- bøyninger som skyldes lagring av rørene, og at mellomrommet (l 1) i det ferdige dobbeltrør (5,6) bare er utfylt med polyuretan-hårdsskummateriale.
