FLOATING PIPELINE Russian patent published in 2016 - IPC F16L1/24 F16L11/133 

FIELD: pipes.

SUBSTANCE: invention relates to pipeline equipment and can be used for transfer of homogeneous fluids, hydraulic mixtures, wastes from oil refining and pulp on dredges in sea, river and marshy environment. Floating pipeline comprises one or more floats, formed by outer surface of elastic pipe 1 and barrel-shaped polymer shell 2. Floats are filled with foamed polymer material 3, and/or gas and/or granulated polymer, wherein float is filled in upper part of foamed polymer material by 10-50 times lower density compared to lower part of float. Furthermore, polymer shell 2 has a barrel shape, reinforced with flexible material 4, and on outer surface of polymer shell 2 there are lugs 5 for attachment of electric cable 6.

EFFECT: technical result is simplification of design, higher reliability and improved operational characteristics of floating pipeline.
