FIELD: pipes.
SUBSTANCE: tube has at least one layer containing polyamide. Layer containing polyamide is a barrier layer produced by means of mixture extrusion containing at least one polyolefin and at least one polyamide copolymer with formation of a laminar structure containing multiple layers of polyamide copolymer in the mass of polyolefin. Pipeline includes, at least, two polymer tubes, which can have one or two walls, wherein the connection of single-wall tubes are made by butt welding, and connection of two-walled pipes is made by means of butt welding of barrier pipes and connecting the barrier pipes by means of electro-welded couplings. Polymer pipe and pipeline have high resistance to fuel permeability and high elasticity.
EFFECT: polymer pipe is intended for transportation of fuel, including light oil products and hydrocarbon gases, at fuel and energy complexes and transportation of fuel and gases, as well as at gas filling stations.
