FIELD: transport.SUBSTANCE: invention relates to hydraulic engineering and can be used for transfer of fluids, oil products, gas and hydraulic mixes. Proposed method of swirling of flow in pipeline and increasing of flow rate along pipeline lengthwise axis. To swirl and spin the flow along lain line lengthwise axis, main line length cross-section is changed by turning signal rectangular section through 10 degrees so that, in nine lengths, pipeline rectangular section is turned through 90 degrees.EFFECT: higher efficiency of main like operation.1 dwg |
