Abstract
The utility model discloses an aluminum alloy plastic-lined composite tube. The aluminum alloy plastic-lined composite tube sequentially comprises an aluminum alloy outer tube layer, a first ethylene/ polyethylene copolymer inner tube layer, a polypropylene inner tube layer, and a second ethylene/ polyethylene copolymer inner tube layer in a concentric mode in the direction from the outer wall to the inner wall of the composite tube. Preferentially, the thickness of the polypropylene inner tube layer is smaller than the thickness of the aluminum alloy outer tube layer and the thickness of the first ethylene/ polyethylene copolymer inner tube layer. Particularly, the thickness of the aluminum alloy outer tube layer is smaller than the thickness of the first ethylene/ polyethylene copolymer inner tube layer and the thickness of the second ethylene/ polyethylene copolymer inner tube layer. The aluminum alloy plastic-lined composite tube is simple in structure, easy to manufacture, low in cost, excellent in physical and chemical performance, long in service life, and suitable for being widely used in the construction industry field, the municipal administration field, the industry field and the agriculture field such as building water supply and drainage, urban and rural water supply and drainage, urban gas, power and optical cable sheaths, industrial fluid conveying and agricultural irrigation.
Description
Technical field
The utility model relates to a kind of tubing, particularly a kind of aluminum alloy lining plastic composite pipe.
Background technique
At present at building industry, municipal administration, industry and all kinds of tubing of field extensive use such as agriculture, to realize the conveying of various flow-like materials or the protections of cable such as gas, liquid.But all there is defect in traditional lead, copper, steel tubing or all types of plastic tubing etc., for example poisonous, working life is short, easily aging, cost is high or capability of electromagnetic shielding is poor etc., is difficult to realize the application of universality.
Model utility content
The purpose of this utility model is to provide a kind of novel aluminum alloy lining plastic composite pipe, thereby overcomes deficiency of the prior art.
For achieving the above object, the utility model has adopted following technological scheme:
An aluminum alloy lining plastic composite pipe, comprises the aluminum alloy external tube layer, the first ethene/polyethylene and ethylene copolymers inner tube layer, polypropylene inner tube layer and the second ethene/polyethylene and ethylene copolymers inner tube layer that along described composite pipe outer wall, to inwall direction, arrange with one heart successively.
Further, the thickness of described polypropylene inner tube layer is less than among described aluminum alloy external tube layer, the first ethene/polyethylene and ethylene copolymers inner tube layer and the second ethene/polyethylene and ethylene copolymers inner tube layer the thickness of any one.
Further, the thickness of described aluminum alloy external tube layer is less than among described the first ethene/polyethylene and ethylene copolymers inner tube layer and the second ethene/polyethylene and ethylene copolymers inner tube layer the thickness of any one.
Compared with prior art, the beneficial effects of the utility model are: this aluminum alloy lining plastic composite pipe is simple in structure, be easy to manufacture, with low cost, and physics, chemical property are good, and long service life, is suitable in the extensive use of a plurality of fields.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of aluminum alloy lining plastic composite pipe in the utility model one preferred embodiment.
Embodiment
Consult Fig. 1, this aluminum alloy lining plastic composite pipe comprises aluminum alloy external tube layer 1, the first ethene/polyethylene and ethylene copolymers inner tube layer 21, polypropylene inner tube layer 3 and the second ethene/polyethylene and ethylene copolymers inner tube layer 22 arranging with one heart successively to inwall direction along described composite pipe outer wall.
In this aluminum alloy lining plastic composite pipe, adopt aluminum alloy as external tube layer, it is high that it has intensity, corrosion stability and oxidation resistance are good, bear pressure large, uvioresistant, the advantages such as antidetonation, make this composite pipe all applicable in underground, air atmosphere or wet environment.
In this aluminum alloy lining plastic composite pipe, adopt ethene/polyethylene and ethylene copolymers as internal layer, make this composite pipe good toughness, intensity is high, processibility is excellent, and creep-resistant property is good under higher temperature, there is energy-saving material-saving, safety non-toxic, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance is easy, long service life
In this aluminum alloy lining plastic composite pipe, adopt polypropylene to form the internal layer mesosphere of this composite pipe, make this composite pipe there is fabulous barrier and fabulous processability to gas, make in addition this composite pipe also have good mechanical strength, stretchability, wear resistance, winter hardiness and surface strength concurrently.
Especially, by the organic assembling of aforementioned three kinds of material layers, make the premium properties reinforcement each other of these three kinds of materials, and made up the defect in this each comfortable performance of three kinds of materials, make this composite pipe at compression resistance, tensile property, the poor deformation nature of heatproof,, the physics of the aspect such as corrosion resistance, Al-alloy pipe, polyethylene pipe and the polypropylene tube that chemical combination property is far superior to commonly see.
Preferably, the thickness of described polypropylene inner tube layer is less than among described aluminum alloy external tube layer, the first ethene/polyethylene and ethylene copolymers inner tube layer and the second ethene/polyethylene and ethylene copolymers inner tube layer the thickness of any one, the use that can save polypropylene material so on the one hand, also keep the performance of this composite pipe simultaneously, and reduce wall thickness.
Particularly preferred, the thickness of described aluminum alloy external tube layer is less than among described the first ethene/polyethylene and ethylene copolymers inner tube layer and the second ethene/polyethylene and ethylene copolymers inner tube layer the thickness of any one.
Preferably, described composite pipe has smooth outer wall and/or smooth inner wall, particularly has smooth outer wall and inwall concurrently, so, makes aluminum alloy outer tube have better corrosion resisting property on the one hand, also makes on the other hand that the energy such as fluid are smooth and easy to be passed through.
Preferably, the pipe thickness of described composite pipe is less than 1/3rd of described composite pipe radius.
Summarize it, this aluminum alloy lining plastic composite pipe is simple in structure, be easy to manufacture, with low cost, and physics, chemical property are good, long service life, is suitable in building industry, municipal administration, industry and agriculture field extensive uses such as building water supply and drainage, town and country plumbing, gas, electric power and cable sheath, industrial fluids conveying, agricultural irrigations.
Be to be understood that; above-mentioned embodiment; be only explanation technical conceive of the present utility model and structure characteristic; object is to allow stakeholder implement according to this; but above said content does not limit protection domain of the present utility model; any equivalence that every foundation Spirit Essence of the present utility model is done changes or modifies, within all should falling into protection domain of the present utility model.
