FLEXIBLE PIPELINE FOR TRANSFER OF CRYOGENIC FLUID AND APPROPRIATE METHOD OF ITS FABRICATION Russian patent published in 2015 - IPC F16L11/115 

FIELD: transport.

SUBSTANCE: invention relates to pipeline (10) with inner corrugated pipe (16) with axis (A-A′) confined by multiple crimps (30) extending radially towards said axis (A-A′) and at least one ply (18) of reinforcements operated under tension and arranged around said corrugated pipe (16). It comprises at least one heat insulating ply (44, 46) arranged around ply (18) of reinforcements. Pipeline (10) comprises inner shell (14) to direct cryogenic fluid flow arranged in said corrugated pipe (16). Note here that inner shell (14) consists of multiple cylindrical segments (50). Every cylindrical segment (50) of inner shell (14) overlaps multiple serial crimps (30) of pipe (16) and comprises outer thrust (54) of axial locking extending to crimp (30) of pipe (16).

EFFECT: increased volume of cryogenic fluid transfer.
