Abstrakty

W systemach ciepłowniczych w Polsce stosowane są już od prawie 10 lat rury preizolowane, które wyparły w nowych inwestycjach, związanych z budową sieci cieplnych, tradycyjne rury układane w kanałach ciepłowniczych. Stosowanie rur preizolowanych za granicą ma miejsce od ponad 30 lat, a wiodącymi krajami pod tym względem są głównie kraje skandynawskiej, tj. Dania, Szwecja i Islandia, a także Finlandia.
