A reinforcement structure and a method of assembly of hose-pipe for heavy or light duty use of thick or thin wall construction in which a non-woven matrix material layer supports the reinforcement members in a winding operation during assembly into the hose. More than one layer of matrix may be utilized. The matrix layer and reinforcement members may be applied in the form of a composite strip or strips pre impregnated with polymeric material, of which the following is a specification.
A flexible hose which is formed by attaching a resin reinforcing coil member to a cylindrical body, the cylindrical body being composed of a nonwoven fabric layer which is formed by winding a nonwoven fabric tape spirally and connecting adjacent side end portions and an air-cut layer which forms on at least one side of the nonwoven layer. The nonwoven fabric tape and the reinforcing coil member are formed of heat-fusible resin materials, and the reinforcing coil member is fused with the nonwoven fabric layer in a body.
A pipe and method of manufacture of the pipe are described. The pipe comprises a core of helically wound steel strip embedded in a plastics material matrix and lined with inner and outer linings of filament wound fiber reinforced plastics material.
A braided hose reinforcement includes left and right turning strips. Each of the strips includes a number of elongated metal elements embedded in a matrix of a polymer material.
A lining material for pipelines such as gas conduits, city water pipelines, sewage pipelines, and petroleum pipelines which having a structure wherein a layer of bulky yarns is fastened to either one of the inner and outer surfaces of a tubular textile jacket and an air-impervious layer made of a rubber or a synthetic resin is bonded to the other surface of the jacket, and exhibits excellent shape-maintaining property against external pressure and earthquake-resistance after being applied to the pipelines.
