Abstract (en)

[origin: WO2005087403A2] The invention relates to a method for producing a fluid conduit, in particular a fluid conduit for a CO2 refrigerating plant. For this purpose, several pipes (5-9) are simultaneously supplied by means of at least one roller (11) which is provided with peripheral grooves (14) and are helically wound in a parallel direction with respect to each other, wherein each pipe (5, 9) is guided along a helical line and the helical lines of all pipes (5, 9) are parallel to each other.
