Multilayer 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 which comprises a plastic pipe, a reinforcing structure and a plastic layer. The plastic pipe is wrapped by the reinforcing structure, the reinforcing structure is wrapped by the plastic layer, and the reinforcing structure comprises a first bonding resin layer, a firststeel wire mesh, a second bonding resin layer, a second steel wire mesh and a third bonding resin layer. The plastic pipe, the bonding resin layers and the steel wire meshes are mutually overlapped toform a multilayer structure, the first bonding resin layer can improve the fixing strength of the first steel wire mesh on the outer surface of the plastic pipe, and the first steel wire mesh and thesecond steel wire mesh are each of a rhombus-shaped net structure and are arranged in a staggered mode in the vertical direction to form a staggered rhombus-shaped net structure with the smaller single rhombus area. By means of the arrangement, the strength and rigidity of internal pressure resistance and external pressure resistance of the multilayer steel wire mesh reinforced composite pipe canbe improved, the pressure resistance is more stable, the pressure resistance is not prone to being lost in the using process, and therefore the service life of the multilayer 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 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.
