Description
(54) ГИБКИЙ ТРУБОПРОВОД(54) FLEXIBLE PIPELINE
1one
Изобретение относитс к области машиностроени и касаетс изготовлени трубопроводов .The invention relates to the field of engineering and concerns the manufacture of pipelines.
Известен гибкий трубопровод, включающий внутреннюю и наружную гофрированные металлические трубы, между которыми расноложен изолирующий слой.Known flexible pipeline, including the inner and outer corrugated metal pipes, between which there is an insulating layer.
Цель изобретени - уменьщение гидравлического сопротивлени во внутренней трубе.The purpose of the invention is to reduce the hydraulic resistance in the inner tube.
Это достигаетс тем, что соотношение между высотой гофр и половиной рассто ни между вершииами соседних гофр внутренней трубы выбрано равным 0,4-1,3, при этом радиус кривизны виадин гофр больше радиуса кривизиы их вершин.This is achieved by the fact that the ratio between the height of the corrugations and half the distance between the vertices of the adjacent corrugations of the inner tube is chosen equal to 0.4-1.3, while the radius of curvature of the viadins corrugation is greater than the radius of curvature of their vertices.
Изобретение ио сн етс чертежом.The invention is illustrated in a drawing.
Гибкий трубопровод включает внутреннюю 1 и наружную 2 гофрированные металлические трубы, между которыми расположен изолируюший слой 3. Радиус кривизны впадинThe flexible pipeline includes inner 1 and outer 2 corrugated metal pipes, between which is located the insulating layer 3. The radius of curvature of the depressions
гофр внутренней трубы больше радиуса их вершин.corrugation of the inner tube is greater than the radius of their peaks.
Соотношение между высотой гофр и половиной рассто ни между вершииами соседних гофр внутренней трубы выбрано равным 0,4- 1,3.The ratio between the height of the corrugation and half the distance between the vertices of the adjacent corrugations of the inner tube is chosen equal to 0.4-1.3.
