Abstract
Sposób gięcia rur dwuwarstwowych polega na tym, że rurę umieszcza się pomiędzy matrycą a rolką gnącą, które nagrzewa się grzałką patronową i poprzez matrycę i rolkę kształtującą nagrzewa się zewnętrzną warstwę rury do temperatury w zakresie od 70 do 150°C. Równocześnie przez wnętrze rury przepuszcza się medium grzejne o temperaturze w zakresie od 50 do 300°C i poprzez medium grzejne znajdujące się wewnątrz rury nagrzewa się wewnętrzną warstwę rury do temperatury w zakresie od 40 do 100°C. Następnie po nagrzaniu warstwy zewnętrznej i warstwy wewnętrznej wygina się rurę.The method of bending two-layer pipes is that the pipe is placed between the matrix and the bending roller, which is heated by a cartridge heater and the outer layer of the pipe is heated to a temperature in the range of 70 to 150 ° C through the matrix and shaping roller. At the same time, a heating medium with a temperature in the range from 50 to 300 ° C is passed through the interior of the pipe and the inner layer of the pipe is heated to a temperature in the range from 40 to 100 ° C through the heating medium located inside the pipe. Then, after heating the outer layer and the inner layer, the pipe is bent.
