FIELD: machine building. ^ SUBSTANCE: invention elates to field of manufacturing and operation of flexible high-pressure hoses (HPH), with tubular braiding, which can be used in area of feeding of liquids or gas under pressure in open or closed systems. High-pressure hose with composite braiding, of inner diametre 4-50 mm, contains internal tubular layer made of rubber, force framework made of two layers of braiding, herewith inner layer of braiding is implemented of pretensioned up to expansion 0.5-10% of fibers, is elastic fixed on external surface of internal tubular layer of hose by means of self-curing up to rubber-like condition of polymer compound, and external layer of braiding is implemented of pretensioned fibers up to expansion for 0.5-5% more, than fibers of internal layer of braiding, is saturated and coated with mentioned above polymer composition, herewith space between internal and external layers of braidings is filled by lubricant for 1-80%. ^ EFFECT: fabrication method of structure provides receiving of HPH with composite braiding with different technical and economic properties and do not requires application of vulcanisation process, application of additional technological layers or braidings, preparation for installation of end fittings. ^ 15 cl, 1 dwg |
