FIELD: machine building.
SUBSTANCE: proposed pipeline comprises flexible pipes with end sections made up of cylindrical rubber-fabric collars with metallic filling elements, and rotary steel flanges arranged on pipes and bolted together. Chamfers are made on collars, on the sides of jointed surfaces. Cylindrical seats are bored in flange end faces, concentric with flange inner diameters, to depth equal to length of collar cylindrical surfaces and with minimum clearances between diameters of grooves and collars to allow free arrangement of collars in flange seats.
EFFECT: simplified mounting and higher reliability.
