Abstract

The invention discloses a multi-layer wound composite tube. The multi-layer wound composite tube comprises a round liner tube, reinforcing layers and a round external-covering tube, wherein the reinforcing layers are arranged between the round liner tube and the round external-covering tube and are at least three in number. The multi-layer wound composite tube is characterized by comprising at least one wound layer with the wound angle alpha and at least two wound layers with the wound angle beta, and the two wound layers with the wound angle beta are crossed and wound to form a net-shaped structure, the alpha is less than 90 degrees and greater than or equal to 80 degrees, and the beta is less than or equal to 65 degrees and greater than or equal to 30 degrees. According to the multi-layer wound composite tube, the ability to bear annular pressure and part of longitudinal pressure of the novel tube can be enhanced, and the annular rigidity grade of the novel tube can be increased; bearing ability to bear the longitudinal pressure and part of the annular pressure of the novel tube can be enhanced. In addition, the multi-layer wound composite tube has the advantages of being small in medium conveying resistance, resistant to corrosion, high in flexibility, capable of being bent and the like.

Description

technical field [0001] The invention relates to a plastic composite pipe, in particular to a multilayer wound composite pipe, which belongs to the technical field of plastic composite pipe design. Background technique [0002] The development and promotion of plastic pipes have been in use for decades. Plastic pipes have been widely used due to their corrosion resistance, wear resistance, hygiene, good circulation, energy saving and environmental protection. In recent years, the improvement of the performance and structure of plastic pipes has attracted the attention of people in the industry, and a large number of steel-plastic composite pipes have emerged, among which steel mesh skeleton plastic (polyethylene) composite pipes are the most typical. [0003] figure 1 It is a structural schematic diagram of the existing steel mesh skeleton plastic composite pipe; figure 2 for figure 1 Distribution map of steel wire arrangement in middle reinforcement layer. [0004] Such...
