FLOATING PIPELINE Russian patent published in 2010 - IPC F16L1/12 F16L1/24 F16L11/00 E02F7/10 

FIELD: machine building.

SUBSTANCE: invention refers to pipeline hydro-transport and can be implemented at construction of pipeline transporting homogenous fluid and hydraulic mixtures. The floating pipeline consists of sections of pipes (2) made out of elastic material and connected with flanges. Each section of pipe (2) has several floats (4) of positive buoyancy in fluid; also the floats are equipped with compensators of lengthwise travel (5). Compensators of lengthwise travel (5) can be made in form of elements fabricated out of flexible material secured in side ears (6) of neighbour floats. End floats (7) of neighbour sections of pipes are connected with arresters of lengthwise travel in form of chains (8) secured in side ears. Chains (8) are supported with poles (10) attached to flanges of pipes. Support facilities for service lines, for example for electric cables, are made on the floats in form of upper ears (11); these facilities are furnished with devices for fastening service lines (14).

EFFECT: ensuring high flexibility at pipeline travel and increased reliability of service lines securing.
