Abstract

The invention is applicable to the field of composite pipes, and provides a steel wire mesh reinforced composite pipe which comprises a plastic pipe, a reinforcing structure and a plastic layer. The plastic pipe is coated with the reinforcing structure, and the reinforcing structure is coated with the plastic layer. The reinforcing structure comprises a first bonding resin layer, a first steel wire layer, a second bonding resin layer, a second steel wire layer and a third bonding resin layer, the plastic pipe, the bonding resin layers and the steel wire layers are stacked to form a multilayerstructure, and the first bonding resin layer can improve the fixing strength of the first steel wire layer on the outer surface of the plastic pipe. The first steel wire layer and the second steel wire layer are respectively formed by spirally winding independent steel wires and form a rhombic net-shaped structure in the vertical direction, so that strength and rigidity of the internal pressure resistance and the external pressure resistance of the steel wire mesh reinforced composite pipe can be improved, the pressure resistance is more stable, the pressure resistance is not liable to lose inthe use process, and therefore, the service life of the steel wire mesh reinforced composite pipe is prolonged.

Description

technical field [0001] The invention belongs to the field of composite pipes, in particular to a steel wire mesh reinforced composite pipe. Background technique [0002] Composite pipe is a pipe based on metal and thermoplastic composite structure, lined with non-metallic materials such as polypropylene, polyethylene or externally welded cross-linked polyethylene, which has the advantages of metal pipes and non-metal pipes. [0003] Commonly used composite pipes include aluminum-plastic composite pipes, steel-plastic composite pipes, aluminum alloy-lined plastic composite pipes, plastic-coated steel pipes, and steel skeleton pipes. Ethylene, a five-layer pipe bonded by glued layers, has the advantages of good corrosion resistance of polyethylene plastic pipes and high pressure resistance of metal pipes; steel-plastic composite pipes are based on seamless steel pipes and welded steel pipes. High adhesion, anti-corrosion, food-grade hygienic polyethylene powder coating or epo...
