Изобретение относитс к области арматуростроени , в частности к гибким трубам.The invention relates to the field of reinforcement, in particular to flexible pipes.
Известны гибкие трубы, арматура которых содержит навитые элементы с углом наклона к оси до 40° работающие на раст жение и сжатие 1. Недостатком этих труб вл етс пониженна прочность навитых элементов,Flexible pipes are known, the reinforcement of which contains wound elements with an angle of inclination to the axis of up to 40 ° working in tension and compression 1. The disadvantage of these pipes is the reduced strength of the wound elements,
С целью повышени прочности навитых элементов в описываемой трубе навитые элементы в поперечном сечении имеют наибольший размер, ориентированный по радиусу гибкой трубы.In order to increase the strength of the wound elements in the described pipe, the wound elements in cross section have the largest size, oriented along the radius of the flexible pipe.
На фиг. 1 показана гибка труба, общий вид; на фигi 2, 3, 4, 5 различные формы сечени профилированных прутков оболочки, обладающей прочностью на раст жение.FIG. 1 shows a flexible tube, a general view; Figures 2, 3, 4, 5 different sections of the section of the profiled sheath bars with tensile strength.
Труба состоит из внутренней гибкой оболочки или .трубчатого сердечника 1, изготовленного из пластического материала, например эластомера , гибкой металлической оболочки 2, окружающей трубчатый сердечник 1, гибкой и герметичной оболочки 3, изготовленной из пластического материала , например эластомера, и покрывающей оболочку 2 так, что давление преобладающее в наружной части тру2The pipe consists of an inner flexible shell or a tubular core 1 made of plastic material, for example an elastomer, a flexible metal shell 2 surrounding the tubular core 1, a flexible and hermetic shell 3 made of plastic material, for example an elastomer, and covering the shell 2 so that that the pressure prevailing in the outer part of the pipe2
бопровода, не может воздействовать непосредственно на трубчатый сердечник 1, и оболочки 4, придающей прочность на раст жение.Оболочка 4 состоит из двух слоев 5 и 6, намотанных по спирали в противоположных направлени х с большим шагом намотки. Каждый слой состоит из металлических профилированных прутков 7.The pipeline cannot directly act on the tubular core 1, and the shell 4, which gives tensile strength. The shell 4 consists of two layers 5 and 6 wound in a spiral in opposite directions with a large winding pitch. Each layer consists of metal profiled bars 7.
На фиг. 2, 3, 4 и 5 показана в разрезе, перпендикул рном к оси трубопровода, часть одного из слоев оболочки, придающей прочность на FIG. 2, 3, 4 and 5 are shown in section, perpendicular to the pipeline axis, a part of one of the layers of the shell, which gives strength to
5 раст жение. На фигурах даны различные формы возможных сечений прутков 7. Сечени могут быть пр моугольными , трапециевидными, Т-образными и 1-образными. При изготовлении обо0 лочки между различными прутками предпочтительно оставл ть промежуток е дл обеспечени передачи лежаицим ниже оболочкам радиальных усилий. Прутки 7 расположены так, что в по1 перечном сечении имеют наибольший размер, ориентированный по радиусу Iгибкой трубы.5 stretch. The figures give various forms of possible cross sections of the bars 7. The sections can be rectangular, trapezoidal, T-shaped and 1-shaped. When making the shell between different rods, it is preferable to leave a gap e to ensure the transfer of the bed below the shells of the radial forces. The rods 7 are arranged so that in each cross section they have the largest size, oriented along the radius of the flexible pipe.
Прутки 7, составл ющие каждый из слоев, создающих прочность на раст 0 жение, могут быть изготовлены из метсшлического материала с хорошими механическими характеристиками и обладгиощего высокой устойчивостью к ко розии от среды, в контакте с которой наход тс прутки. Но, если необходимо изготовит гиб кий герметичный трубопровод малого веса, то прутки 7 можно отформовать в виде матрицы, из смолы, армированной усилием из параллельных нитей, Матрица может быть выполнена из термореактивной смолы ненасыщенного полиэфира или эпоксидной смолы и т.д. Усиление может состо ть из волокон с высоким модулем упругости, используемых в виде непрерывных нитей илиThe rods 7 constituting each of the layers creating tensile strength can be made of a metallic material with good mechanical characteristics and possess high resistance to corrosion from the medium in contact with which the rods are. But if you need to make a flexible sealed pipeline of light weight, then the rods 7 can be molded in the form of a matrix, made of resin reinforced with force from parallel threads. The matrix can be made of thermosetting resin of unsaturated polyester or epoxy resin, etc. The reinforcement may consist of high modulus fibers used as continuous filaments or
