| titleOfInvention | Method of improving the physical properties in the production of PSPs (plastic-sheathed pipes) |
| abstract | The present invention relates to a process for producing insulated pipes, which comprises the steps (A) provision of pipe for a medium and outer pipe, where the pipe for a medium is arranged within the outer pipe and an annular gap having ends E 1 and E 2 is formed between the pipe for a medium and outer pipe, (B) introduction of a polyurethane system comprising at least one isocyanate component (a) and at least one polyol mixture (b) into the annular gap at the end E 1 and (C) foaming and curing of the polyurethane system, wherein the annular gap is closed by means of a cap at the end E 2 and this cap has openings having an adjustable size, a cap which has openings having an adjustable size, the use of this cap for producing insulated pipes and also an insulated pipe which can be produced by the above-described process of the invention. |
