FIELD: machine building.
SUBSTANCE: structure of the pipeline includes a self-supporting metal inner layer and polymer outer layer. Preferably, a thin metal layer is a material resistant to corrosion, such as corrosion-proof stainless steel or titanium. In a preferred example of invention implementation, the external supporting polymer layer is glass fabric impregnated with polyimide resin. Method of manufacture of laminar structure is described.
EFFECT: invention improves pipeline reliability.
