Abstract: Insulated pipe, comprises a medium pipe; polyurethane-foam material, obtained by reaction of an isocyanate component with a polyol mixture; and jacket pipe, where the polyol mixture comprises at least a polyether polyalcohol, which is obtained by the alkoxylation of saccharose, diethyleneglycol and optionally pentaerythrite and/or glycerin with ethylene oxide and/or propylene oxide, and exhibits a isocyanate functionality of greater than 3, a hydroxyl number of greater than 300 mg of potassium hydroxide (KOH)/g and a viscosity of less than 2500 mPas at 25[deg]C in accordance with DIN 53019. An independent claim is included for the preparation of insulated pipe comprising providing the medium pipe and the jacket pipe, where the medium pipe is arranged within the jacket pipe, and preparing the polyurethane-foam material.
