Technical field
The utility model relates to a kind of high pressure steel-plastic composite pipe with multi-layer compound structure, particularly a kind of high pressure steel-plastic composite pipe that is used for industries such as fire-fighting high pressure pipe line system, natural gas transmission, high-rise building plumbing, mining, chemical industry belongs to the renovation technique of composite pipe.
Background technique
At industry fields such as fire-fighting high pressure pipe line system, natural gas transmission, high-rise building plumbing, mining, chemical industry, all need to bear the pipe-line system that the long distance of elevated pressures is carried, this pipe-line system both had higher requirement to resistance to compression, the shock resistance of tubing, took into account environmental protection, the sanitation performance of tubing again.Existing adopt steel-plastic composite pipe mostly, but the resistance to compression of traditional steel-plastic composite pipe, shock resistance is not good enough.
The model utility content
The purpose of this utility model just is to provide a kind of high pressure steel-plastic composite pipe with more outstanding resistance to compression, shock resistance.
The technical solution of the utility model is: high pressure steel-plastic composite pipe of the present utility model; body includes plastic inner pipe from inside to outside successively; adhesive-layer; steel pipe; adhesive-layer; plastic protective layer; enhancement layer; outer plastic protective layer; bond together by adhesive-layer between the outer wall of plastic inner pipe and the inwall of steel pipe; bond together by adhesive-layer between the outer wall of plastic inner pipe and the inwall of plastic protective layer; the outer felt of plastic protective layer is around one deck enhancement layer at least; the outside of enhancement layer coats at least the outer plastic protective layer of one deck, between plastic protective layer and the enhancement layer and enhancement layer be one with protecting outward between the plastic layer by hot melt adhesive.
Above-mentioned enhancement layer radially or with the radially angled outer surface that is wrapped in plastic protective layer.
The material of above-mentioned enhancement layer is enhancing rope, the band that steel wire or steel wire are made, the thread bundle that aramid fibre, polyster fibre or polyester fiber are made, strand shape rope, reinforcing band.
The main material of above-mentioned outer plastic protective layer and plastic protective layer is any in polyethylene, polypropylene, polybutylene, polyurethane, polystyrene, PVC, acrylonitrile-butadiene-styrene copolymer or the ethylene-vinyl acetate copolymer.
The utility model is owing to adopt in the outer felt of plastic protective layer around the structure of one deck enhancement layer at least; and the outside of enhancement layer coats the outer plastic protective layer of one deck at least; characteristics such as the high strength that has because of enhancement layer, high-modulus; therefore, the utlity model has more outstanding resistance to compression, shock resistance.The utility model is a kind of reasonable in design, the high pressure steel-plastic composite pipe that practicability is good, its using scope and purposes are wide, can be used for industry, social efficiency and remarkable in economical benefits such as fire-fighting high pressure pipe line system, natural gas transmission, high-rise building plumbing, mining, chemical industry.
