FIELD: curved delivery pipelines engineering. SUBSTANCE: device has pipe portions connected to each other by mating assemblies not preventing curvatures of pipeline in different planes. Mating assemblies are made in form of corrugated elastic branch pipes of wavy profile. Ends of elastic branch pipe are made in form of flanges, which are mounted with possibility of interaction with flanges of adjacent portions of pipes and pressing to them by ring-shaped straps. Length of round-linked chains in tensioned state is selected with consideration of maximally acceptable strength during extension of elastic branch pipe. EFFECT: increased reliability and efficiency of pipeline operation. 3 cl, 5 dwg |
