Abstract
Przedmiotem wynalazku jest sposób wytwarzania rur preizolowanych, zwłaszcza kształtek stalowych lub wykonanych z rur przewodowych z tworzyw sztucznych preizolowanych poprzez nałożenie na rury przewodowe warstwy izolacyjnej poliuretanowej, a na nią warstwy zewnętrznej - w tym antydyfuzyjnej, mające zastosowanie do produkcji rurowych elementów transportu cieczy, zwłaszcza płynów grzewczych, chłodniczych. Sposób wytwarzania rur preizolowanych, zwłaszcza kształtek stalowych lub wykonanych z rur przewodowych z tworzyw sztucznych preizolowanych poprzez nałożenie na rury przewodowe warstwy izolacyjnej poliuretanowej, a na nią warstwy zewnętrznej, polega na tym, że na koncentrycznie usytuowany metalowy lub z tworzywa sztucznego środek transportu płynu zwłaszcza rury lub kształtki w postaci kolana giętego albo spawanego z segmentów, lub zwężki, lub trójnika, lub zaworu kulowego nakłada się współosiowo osłonę metalową, szczelną dla dyfuzji gazu znajdującego się w izolacji poliuratanowej, po czym końce wyrobu zamyka się szczelnie, a następnie tak powstałą przestrzeń powstałą pomiędzy środkiem transportu medium a osłoną metalową wypełnia się poliuretanem, dalej powierzchnię zewnętrzną osłony metalowej pokrywa się warstwą poliolefiny w temperaturze w zakresie 160 do 250, korzystnie 220°C.The subject of the invention is a method for the production of pre-insulated pipes, especially steel fittings or made of pre-insulated plastic line pipes by applying polyurethane insulation layer on line pipes, and an external layer on it - including anti-diffusion layer, applicable to the production of liquid transport pipes, especially liquids heating, cooling. The method of producing pre-insulated pipes, especially steel fittings or pipes made of plastic pre-insulated pipes by applying a polyurethane insulation layer to the pipes, and an outer layer on it, consists in the concentric position of a metal or plastic fluid transport, especially pipes or fittings in the form of a bent or welded knee from segments, or a reducer, or a tee, or a ball valve are applied coaxially with a metal sheath, tight for diffusion of gas in polyuratane insulation, after which the ends of the product are sealed, and then the resulting space between the medium of transport and the metal sheath is filled with polyurethane, further the outer surface of the metal sheath is covered with a layer of polyolefin at a temperature in the range of 160 to 250, preferably 220 ° C.
