METHOD APPLIED FOR PIPELINE ARRANGEMENT TO PERFORM FIBRE-OPTIC REMOTE MEASUREMENT, PIPELINE USED TO PERFORM FIBRE-OPTIC REMOTE MEASUREMENT, AND DEVICE TO BE USED IN PIPELINE IN ORDER TO PERFORM FIBRE-OPTIC REMOTE MEASUREMENT Russian patent published in 2012 - IPC F16L1/36 F16L39/00 

FIELD: machine building.

SUBSTANCE: multiple pipe sections (11) each of which has inner pipe (13) enveloped with material layer(-s) are provided. Opposite ends (17A) of each pipe section have the section where the enveloping layer(-s) are removed or non-available. Tubular element (19) passes longitudinally along each pipe section inside enveloping layer(-s) and has free ends (19A) which protrude from the corresponding end walls (20A) of the enveloping layer (-s) beyond the corresponding ends of each pipe section. Neighbouring pipe sections are connected together. Tubular elements of neighbouring pipe sections are connected together in order to form a channel that passes along the pipeline. Channel is made so that it is possible to arrange one or more fibre light waveguides in it. At least one second layer of material is applied to area between connected pipe sections. Enveloping layer and at least one second layer ensure insulation and/or protection of inner pipes of pipeline.

EFFECT: reduction of the number of connection devices for light waveguide; reduction of optic signal losses.
