FIELD: construction.
SUBSTANCE: pipeline section comprises a multi-layer protective jacket acting as an auxiliary pipeline. The pipeline design comprises the main metal pipe with the multi-layer protective jacket that surrounds this pipe and is separated from it with a circular gap. The multi-layer jacket comprises an inner layer of a metal coating and a layer of an outer coating from a polymer material. Preferably the thin layer of the metal coating is made of a corrosion-resistant material, such as corrosion-resistant stainless steel and/or titanium. In one of versions of invention realisation the polymer coating is arranged from a polyimide material, such as glass tissue impregnated with polyimide resin. The method to manufacture a pipeline is described.
EFFECT: invention improves reliability of pipeline connection.
