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.So-called heat insulated double pipes (5.6) having a heat insulation layer (15) of polyurethane hard foam material can be made with better insulation effect and without heat / cold bridges by aligning the pipes (5,6) before the foaming in the intermediate space (11). apart, so as to eliminate deflections due to storage of the tubes, and that the gap (1) in the finished double tube (5,6) is filled only with polyurethane hard foam material.
