A multi-layer steel wire mesh reinforced composite pipe

Abstract

The invention is applicable to the field of composite pipes, and provides a multilayer steel wire mesh reinforced composite pipe, including a plastic pipe, a reinforcement structure and a plastic layer; the reinforcement structure covers the plastic pipe, the plastic layer covers the reinforcement structure, and the reinforcement structure Including the first bonding resin layer, the first steel wire mesh, the second bonding resin layer, the second steel wire mesh and the third bonding resin layer, the present invention adopts plastic pipes, bonding resin layers and steel wire mesh to overlap each other to form a multi-layer structure, the first bonding resin layer can improve the fixing strength of the first steel mesh on the outer surface of the plastic pipe, the first steel mesh and the second steel mesh both have a diamond-shaped mesh structure, and are staggered in the vertical direction to form a single diamond-shaped area Smaller staggered diamond-shaped mesh structure, this setting can improve the internal pressure and external pressure resistance and stiffness of the multi-layer steel mesh reinforced composite pipe, and the pressure resistance is more stable, and it is not easy to lose the compressive strength during use. Thereby prolonging the service life of the multi-layer steel wire mesh reinforced composite pipe.

Description

technical field [0001] The invention belongs to the field of composite pipes, in particular to a multilayer 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 coa...

Problems solved by technology

[0004] However, the existing steel wire skeleton polyethylene pipe still has the problem of unstable pressure resistance. During its use, its compressive strength will gradually decrease, and its service life is shorter than other types of pipes.
