Abstract
The utility model provides a composite tube which comprises an inner layer and an outer layer. The composite tube is characterized in that an interlayer is arranged between the inner layer and the outer layer, the interlayer and the inner layer are connected through special hot melt adhesive A, and the interlayer and the outer layer are connected through hot melt adhesive B. Disconnection of a tube body due to the fact that bonding of plastic steel materials is weak and changes along with the temperature is effectively avoided. The inner layer and the outer layer are both high-density polyethylene (HDPE) layers. The surface of a steel wire mesh layer is plated with a copper layer so that the steel wire mesh layer can have a reliable electrochemistry anti-corrosion ability. The composite tube integrates advantages of steel and plastic materials and has excellent comprehensive property. The steel wire mesh layer enables the composite tube to have innate traceable property, a tracing device does not need to be embedded and arranged additionally, a magnetic metal detector can be used for tracing, excavation damage can be effectively avoided, and convenience is brought to safe operation, emergency and maintenance. The composite tube is simple and unique in structure, high in strength, compression-resistant, impact-resistant, and long in service life.
Description
Technical field
The utility model relates to the tubing technical field, relates in particular to a kind of composite pipe.
Background technique
As everyone knows, existing tubing mostly is individual layer tubing, its poor toughness, easy to crack, it is composite pipe that minority tubing is also arranged, although the general individual layer tubing of Toughness Ratio is high, not easy to crack, but still can not reach the required of people, its toughness is still waiting to improve, and also has a kind of composite pipe, it is interior, outer two-layer interior adding steel wire, make its toughness reach the required of people, but bonding insecure, when being subject to the variation of ambient temperature and medium temperature, easily throw off, thereby cause Quality Down, severe one can be accelerated the body cracking because of the steel wire oxidation of inside, has a strong impact on the working life of tubing.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of composite pipe, comprise internal layer, skin, it is characterized in that being provided with the mesosphere between described internal layer and the skin, be connected by hot melt adhesive special A between described mesosphere and the internal layer, be connected by hot melt adhesive special B between described mesosphere and the skin.
Described internal layer and skin are the HDPE layer.
Described mesosphere is steel screen layer.
Described steel screen layer surface is coated with a bronze medal layer.
The beneficial effects of the utility model are: the steel wire surface is coated with a bronze medal layer, make it have more reliably electrochemical anti-corrosive ability, the utility model integrates the advantage that steel is moulded bi-material, this tubing has remarkable combination property, and owing to having adopted hot melt adhesive special A, the B context layer as inside and outside layer, the bonding that can effectively overcome plastic-steel material is insecure.The existence of steel screen layer in the composite pipe; determined that composite pipe has inborn traceability, needn't bury underground in addition and follow the tracks of or the protection mark, namely available magnetic-metal detector is sought track; can effectively avoid excavate destroying, for safe operation and speedily carry out rescue work and maintenance provides a great convenience condition.The utility model is simple in structure, and intensity is high, and resistance to compression is shock-resistant, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the 1-internal layer, 2-is outer, 3-mesosphere, 4-hot melt adhesive special A, 5-hot melt adhesive special B.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail;
As shown in Figure 1, be provided with mesosphere 3 between the internal layer 1 and outer 2, be connected by hot melt adhesive special A4 between described mesosphere 3 and the internal layer 1, be connected by hot melt adhesive special B5 between described mesosphere 3 and the skin 2.Internal layer 1 is the HDPE layer with outer 2, and mesosphere 3 is steel screen layer, and the steel screen layer surface is coated with a bronze medal layer.
The steel wire surface is coated with a bronze medal layer and replaces traditional steel wire, make it have more reliably electrochemical anti-corrosive ability, the utility model integrates the advantage that steel is moulded bi-material, this tubing has remarkable combination property, and owing to having adopted the context layer of hot melt adhesive special as inside and outside layer, the bonding that can effectively overcome plastic-steel material is insecure, throws off phenomenon and vary with temperature the body that causes.The existence of steel wire in the composite pipe; determined that composite pipe has inborn traceability, needn't bury underground in addition and follow the tracks of or the protection mark, namely available magnetic-metal detector is sought track; can effectively avoid excavate destroying, for safe operation and speedily carry out rescue work and maintenance provides a great convenience condition.The utility model uniqueness simple in structure, intensity is high, and resistance to compression is shock-resistant, and creep resistance overcomes the rapid crack propagation of common polythene pipe, long service life.
Accompanying drawing of the present utility model is cylindrical, and it also can be other shape, should not be subject to the restriction of accompanying drawing.
