Embodiment 1

[0017] Embodiment 1, the present invention is composed of two or more than two tile-shaped skeleton sheets to form an inner skeleton 1, and the outer periphery of the inner skeleton 1 is covered with a composite layer 2 of 1 layer, 2 layers, or more than 2 layers, The inner skeleton 1 can be made of metal or non-metallic materials, and of course also includes polymer materials and their modified alloy materials, and the composite layer 2 can be made of polymer materials or modified alloy materials and wound inside On the outer wall of frame 1. The cross-sectional shape of the inner skeleton 1 is circular, semi-square and semi-circular, square-chamfered, or other regular or irregular shapes. The present invention can also be fixedly connected with hollow or solid reinforcing ribs 3 on the outer wall of the inner frame 1, and the cross-sectional shape of the reinforcing ribs 3 can be made into a circle, an arc, a square, or a trapezoid, and the distribution of the reinforcing ri...

Embodiment 2

[0019] Embodiment 2, the present invention can also be equipped with a reinforcing layer 4 embedded in the inner frame 1, and the reinforcing layer 4 can be made of grid-shaped or strip-shaped materials to strengthen the strength of the pipe wall. see Figure 5 and Image 6 , all the other are with embodiment 1.

Abstract

A combining double-wall composite pipe mainly aims at solving the technical problems of relatively complicated production process, higher production cost and the like of the existing large-diameter plastic pipe. The technical scheme of the combining double-wall composite pipe is as follows: an internal skeleton (1) is formed by the combination of two or more tile-shaped skeleton pieces; and one ormore layers of composite layers (2) are covered on the periphery of the internal skeleton (1); the cross section of the internal skeleton (1) takes the shape of a circle, a square, a semi-square semi-circle, or an chamfer square; and a reinforcing layer (4) can also be embedded in the tile-shaped skeleton pieces of the internal skeleton (1). By firstly combining the internal skeleton and then covering the composite layer, the production process is simpler. The combining double-wall composite pipe not only can produce large-diameter composite material pipes, but also can make use of waste plastic materials and the like for production, with relatively low production cost.

Description

technical field [0001] The invention relates to a composite pipe. Background technique [0002] At present, the production process of existing large-diameter plastic pipes is relatively complicated, and the production cost is relatively high. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a combined double-wall composite pipe which can be produced with large diameter and relatively low production cost. [0004] The technical solution adopted by the present invention to solve its technical problems is: the inner skeleton 1 is composed of two or more tile-shaped skeleton sheets, and the outer periphery of the inner skeleton 1 is covered with one or more composite layers 2. The cross-sectional shape of the inner skeleton 1 includes circle, square, semi-square and semi-circle, or square with chamfered corners. A reinforcement layer 4 can also be embedded in the tile-shaped skeleton sheet of the inner skeleton 1, and the reinforcement lay...
