Abstract: Insulated pipe comprises medium pipe, polyurethane-foam material containing glycine and N-((2-hydroxy-5-nonylphenyl)methyl)-N-methyl-mono sodium salt (CAS number 56968-08-2) and jacket pipe; where the polyurethane-foam material in present between the medium pipe and jacket pipe. An independent claim is included for a procedure for the production of insulated pipes, comprising providing the medium pipe and jacket pipe, where the medium pipe is arranged within the jacket pipe; and producing polyurethane-foam material by reacting an isocyanate component with a polyol mixture between medium pipe and jacket pipe, where the glycine and N-((2-hydroxy-nonylphenyl)methyl)-N-methyl monosodium salt are mixed with isocyanate component and/or the polyol mixture before the reaction of isocyanate component with the polyol mixture.
