Abstract
The utility model relates to a bushing pipe in flexible, in proper order by inlayer, intermediate level, outer layer composition, thermoplastic cooling shaping is extruded through the extruder in succession to the inlayer from inside to outside, and the surface of inlayer is provided with intermediate level, intermediate level form weaving through the circle loom after the twisting of aramid fiber material plying, and the surface in intermediate level is provided with it is outer, thermoplastic rubber cooling shaping is extruded through the extruder in succession to the skin. Through penetrating bushing pipe in flexible composite new -laid pipeline or being on active service in the pipeline of fixing time, solved the inside corrosion problems of pipeline, lengthened the service life of pipeline, reduce and carry the cost.
Description
Technical field
The utility model relates to a kind of internal lining pipe, particularly about a kind of flexible compound internal lining pipe.
Background technology
The at present feed-line of underground and ocean engineering aspect, majority is steel material. But along with time of delivery constantly prolongsLong, the continuous corrosion of pumped (conveying) medium, the wall thickness of pipeline attenuate gradually, in the situation that discharge pressure is constant, the leakage thing of pipelinePart takes place frequently, and these occur leak pipelines be to be all embedded under underground or seabed substantially, because the distance of pipeline is very long, short1 kilometer, long tens kilometers, kilometers even up to a hundred, search leakage point and excavation and repairing is all wasted time and energy, and price veryHeight, repairs whole piece pipeline difficulty.
This patent has proposed a kind of flexible compound internal lining pipe just under this background.
Utility model content
Main purpose of the present utility model is to provide a kind of flexible compound internal lining pipe, adopts corrosion-resistant resistance to height by internal layerThe nonmetallic materials of temperature, intermediate layer adopts pressure-bearing fibrous material, and the outer anti-friction material that adopts, can resist pumped (conveying) medium to flexibilityThe corrosion of compound lining pipe also can be born discharge pressure, by flexible compound internal lining pipe being penetrated into the pipeline of new paving or having takenIn the pipeline of labour certain hour, solve the internal corrosion problem of pipeline, extended the service life of pipeline, reduced and carry intoThis.
The purpose of this utility model is realized by following technical scheme:
A kind of flexible compound internal lining pipe is made up of internal layer, intermediate layer, skin from inside to outside successively, it is characterized in that described inLayer is by the continuous extrusioning thermoplastic plastic's cooling forming of extruder, and the outer surface of described internal layer is provided with described intermediate layer, described inIntermediate layer is after aramid fiber material doubling twisting, to pass through circular weaving machine, and braiding forms, described in the outer surface in described intermediate layer is provided withSkin, described skin is by the continuous extruded thermoplastic rubber of extruder cooling forming.
Described internal layer can adopt Kynoar or nylon or heat-proof polythene or crosslinked polyethylene.
Described intermediate layer weaves when described internal layer is extruded, and the extrudate of described internal layer enters the braiding of described intermediate layerIn the grid of band, sharply cooling after, described internal layer is connected with described intermediate layer viscosity.
The described outer TPUE elastomeric material that adopts is extruded cooling forming, described skin and described centreLayer viscosity connects.
The beneficial effects of the utility model: the utility model flexible compound internal lining pipe adopts corrosion-resistant and high-temperature resistant by internal layerNonmetallic materials, intermediate layer adopts pressure-bearing fibrous material, the outer anti-friction material that adopts, can resist pumped (conveying) medium multiple to flexibilityClose the corrosion of internal lining pipe and can bear discharge pressure, by flexible compound internal lining pipe being penetrated into the pipeline of new paving or being on active serviceIn the pipeline of certain hour, solve the internal corrosion problem of pipeline, extended the service life of pipeline, reduced and carry cost.
Brief description of the drawings
Fig. 1 is the schematic diagram of flexible compound internal lining pipe.
Major label description in figure:
1-internal layer; 2-intermediate layer; 3-skin.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in detail.
A kind of flexible compound internal lining pipe is made up of internal layer 1, intermediate layer 2, outer 3 from inside to outside successively, and internal layer 1 is by extrudingThe continuous extrusioning thermoplastic plastic's cooling forming of machine, thermoplastic adopts Kynoar. In the middle of the outer surface of internal layer 1 is provided withLayer 2, intermediate layer 2 is after aramid fiber material doubling twisting, to pass through circular weaving machine, and braiding forms band, and extrude at internal layer 1 in intermediate layer 2Braiding simultaneously, the extrusion pin of internal layer 1 enters 2 inside, intermediate layer, sharply cooling after, internal layer 1 is connected with intermediate layer 2 viscosity, centreThe outer surface of layer 2 is provided with outer 3, outer 3 and adopts TPUE elastomeric material to extrude cooling forming, and outer 3After cooling, be connected with intermediate layer 2 viscosity.
The above, be only preferred embodiment of the present utility model, not the utility model done any formalRestriction, any simple modification that every foundation technical spirit of the present utility model is done above embodiment, equivalent variations andModify, all still belong in the scope of technical solutions of the utility model.
