Abstract

The invention provides a flexible composite pipe. The flexible composite pipe comprises an inner pipe and a composite outer pipe composed of a steel pull net layer and a filling layer; the steel pull net layer is formed by regularly arranging a plurality of elastic steel strips in the circumferential direction of the inner pipe; and each elastic steel strip comprises a plurality of steel wires with rhombic grid structures, and the rhombic grid structures are perpendicular to the pipe wall of the inner pipe and are filled and fixed by the filling layer. The flexible composite pipe can have mechanical properties such as pressure bearing and stretching, and construction properties such as flexibility and air tightness, and has relatively low production cost. Meanwhile, the invention further provides a production method and production device of the flexible composite pipe, and the production method and the production device are used for producing the flexible composite pipe.

Description

technical field [0001] The present application relates to the technical field of composite pipes, in particular to a flexible composite pipe, and a method and device for producing the flexible composite pipe. Background technique [0002] The flexible composite pipe is a composite pipe fitting with corrosion resistance, high pressure bearing and flexibility by winding the middle reinforcement layer between the two layers with the polymer material as the inner and outer layers. At present, materials for the middle reinforcement layer of flexible composite pipes include high-strength fibers such as aramid fibers, polyester fibers, and glass fibers, as well as steel skeletons such as steel wires, steel cords, and steel belts. Among them, the steel skeleton composite pipe combines the advantages of steel pipe and plastic pipe, and has excellent performance in terms of mechanical strength, corrosion resistance and heat resistance, and is widely used in building water supply and d...
