Apparatus for reducing hydraulic losses in the pipeline

摘要

The invention relates to pipelines and can be used in various fields of technology in the transportation of two-phase flows, in particular pulp and viscous structured liquids, oil and neftegazozhidkostnyh mixtures containing sand and other mechanical impurity, through pipelines and is aimed at simplifying the device structure. Said technical result is achieved in that the device for reducing the hydraulic losses in the pipeline, comprising means for liquid flow twisting, arranged inside the pipe 1 in the pipe joint area 2 and is made in the form of pipe section 3 of length L, equal to one turn of helix 4, in surface of the pipe segment 3 is made, at least, at least four helical lines 4, which are rectangular in cross-section the channels 6, which are mounted in a removable, flexible plate 7 with thickenings at their ends contacting ue to the inner surface of the pipeline 1. The tube section 3 may be made, e.g., of composite material. Removable flexible plate 7 in cross section formed in the form of a nail with a cap, which is the longest part h≤R / 10 where R - radius of the tube segment. Removable flexible plate 7 made for example of rubberized nylon material.
