Technical field
The utility model relates to waste pipe field, relates in particular to a kind of steel and moulds winding composite high-strength waste pipe.
Background technique
Steel-plastic composite pipe is a kind of emerging composite pipe tubing, and steel, is a kind of ferrous material; Mould, refer to plastics.Steel-plastic composite pipe is to using normal carbon steel pipe as matrix, the thermoplastic pipes that liner chemical stability is good, and through cold drawn compound or rotationally molding, the mechanical property of its existing steel pipe, has again the corrosion-resistant of plastic tube, slow fouling, the feature of difficult growth microorganism.The purposes of steel-plastic composite pipe is very extensive, is often applied in oil, natural gas transport, work pipes for mining, water drinking tube, the fields such as waste pipe.Steel-plastic composite pipe is when being used as waste pipe, and because most waste pipes all will be embedded in undergroundly, so higher to the requirement of strength of steel-plastic composite pipe, the intensity of existing most of steel-plastic composite pipe all has much room for improvement.
Model utility content
For the deficiency existing in above-mentioned technology, the utility model provides a kind of steel simple in structure, that intensity is high to mould composite drainage pipe.
For achieving the above object, the utility model provides a kind of steel to mould and is wound around composite high-strength waste pipe, comprises inner layer plastic tube, outer layer metal tube and reinforced layer; Described inner layer plastic tube is fixedly connected with outer layer metal tube, and described reinforced layer is fixed between inner layer plastic tube and outer layer metal tube; The cross section of described reinforced layer is tapered protrusion, and the bottom of adjacent conical projection interconnects.
Wherein, described reinforced layer is steel gusset, and described steel gusset is welded on outer layer metal tube with helical.
Wherein, the inside of described tapered protrusion is hollow.
Wherein, the outside of described outer layer metal tube is provided with anticorrosive coat.
Wherein, the material of described inner layer plastic tube is high density polyethylene (HDPE).
The beneficial effects of the utility model are: compared with prior art, the steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, and outer layer metal tube has the mechanical property of metal, and intensity is high; Inner layer plastic tube has corrosion-resistant, slow fouling, the advantage of difficult growth microorganism; The more important thing is and between inner layer plastic tube and outer layer metal tube, be also provided with reinforced layer, further improve the intensity of waste pipe, the shape of cross section of reinforced layer is taper, and the reinforced layer of this shape makes the support performance of waste pipe good, and ring stiffness is high, and intensity is high.The utility model is simple in structure, and production difficulty is low, with low cost, has economic advantages; Take into account the advantage of metal tube and plastic tube, existing good mechanical property, corrosion-resistant and fungi-proofing again.
Accompanying drawing explanation
Fig. 1 is that steel of the present utility model is moulded the longitudinal section schematic diagram that is wound around composite high-strength waste pipe.
Primary component symbol description is as follows:
11, inner layer plastic tube 12, outer layer metal tube
13, reinforced layer
Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1, the steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, comprises inner layer plastic tube 11, outer layer metal tube 12 and reinforced layer 13; Inner layer plastic tube 11 is fixedly connected with outer layer metal tube 12, and reinforced layer 13 is fixed between inner layer plastic tube 11 and outer layer metal tube 12; The cross section of reinforced layer 13 is tapered protrusion, and the bottom of adjacent conical projection interconnects.
Compared to prior art, the steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, and outer layer metal tube 12 has the mechanical property of metal, and intensity is high; Inner layer plastic tube 11 has corrosion-resistant, slow fouling, the advantage of difficult growth microorganism; The more important thing is between inner layer plastic tube 11 and outer layer metal tube 12 and be also provided with reinforced layer 13, further improve the intensity of waste pipe, the shape of cross section of reinforced layer 13 is taper, and the reinforced layer 13 of this shape makes the support performance of waste pipe good, ring stiffness is high, and intensity is high.The utility model is simple in structure, and production difficulty is low, with low cost, has economic advantages; Take into account the advantage of metal tube and plastic tube, existing good mechanical property, corrosion-resistant and fungi-proofing again.
The steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, and reinforced layer 13 is steel gusset, and steel gusset is welded on outer layer metal tube 12 with helical.Steel gusset has good support performance and very high intensity, guarantees ring stiffness and the intensity of waste pipe, and adopts helical to be welded on outer layer metal tube 12, is connected firmly stable, and the mechanical property of the surrounding of assurance waste pipe is consistent.
The steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, and the inside of tapered protrusion is hollow.Because the shape of tapered protrusion has good support performance, inside is made as after hollow, still can guarantee good support performance and intensity.The inside of tapered protrusion is made as to hollow, can not only reduces the use of material, reduce production costs, and can also significantly reduce the quality of waste pipe, make waste pipe lightweight and firm.
The steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, and the outside of outer layer metal tube 12 is provided with anticorrosive coat.Because waste pipe needs buried underground mostly, corrosion for fear of soil to waste pipe, in the arranged outside of outer layer metal tube 12 anticorrosive coat, make waste pipe there is good corrosion resistance, can be arranged in for a long time underground and not because corrosion damages, significantly extend the working life of waste pipe, improve the functional reliability of waste pipe.
The steel that the utility model provides is moulded and is wound around composite high-strength waste pipe, and the material of inner layer plastic tube 11 is high density polyethylene (HDPE).The advantages such as high density polyethylene (HDPE) has with low cost, and chemical stability is good, long service life.Certainly this only belongs to a specific embodiment of the present utility model, and the material of inner layer plastic tube 11 of the present utility model is not limited in this, can be also the plastics of other types.
Disclosed is above only several specific embodiment of the present utility model, but the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
