Abstract
The utility model discloses a novel plastic coated pipe and belongs to the pipe field. The novel plastic coated pipe comprises a steel pipe; the steel pipe is provided with a large aperture end and a small aperture end; an internal convex structure is arranged at the position of the large aperture end; a first erosion resistant coating and a second erosion resistant coating are respectively arranged on an internal wall and an external wall of the steel pipe; positions of two sections of end-to-end plastic coated pipes are convenient to be fixed in installation due to the internal convex structure; and good corrosion resistance of the plastic coated pipe is guaranteed due to the internal and external erosion resistant coatings. The novel plastic coated pipe solves the problems that traditional pipes such as internal coating external plating type pipes and internal plastic coated and external plating type plastic coated pipes are easy to corrode, short in service life, inconvenient to install and the like. According to the technical scheme, the novel plastic coated pipe is mainly applied to the fields of water supply for buildings, fire-fighting devices, underground cable laying and the like.
Description
Technical field
The utility model belongs to tubing, specifically, relates in particular to a kind of novel plastics coated tube.
Background technique
In laying, building water supply, fire fighting device and underground cable often need to use tubing, because health, environmental protection, problem such as energy-conservation become increasingly conspicuous, country clearly is defined in and eliminates in the construction project and the inside and outside Coating Steel Pipe of restriction use and various compounded cast iron pipe material for water supply, the using scope of external zinc coated pipe material is further dwindled in making, production quantity descends, and inside and outside Coating Steel Pipe tubing is eliminated gradually; Be coated with in people bring into use outer plating type and in mould the tubing of outer plating type, adopt materials such as the polyethylene that meets the state health standards performance or epoxy resin because tubing is inner, make prolong greatly service time, but the prolongation along with service time, it is found that the outside zinc coat of the plastics coated tube that is coated with outer plating in the employing is subjected to the influence of aspects such as environment easily, its surperficial coating is damaged easily and is difficult for repairing, and causes the pipe corrosion of plastics coated tube inside, has reduced its working life; When mounted, often need to adopt accessory to carry out the fixed installation of pipeline, to repairing because the coating that damages is installed, often waste time and energy, can not improve the installation efficiency of pipeline when mounted.
Summary of the invention
The utility model discloses a kind of novel plastics coated tube, solved be coated with in of the prior art outer plating type tubing and in mould that outer plating type plastics coated tube exists perishable, working life short and inconvenient problem is installed.
The utility model is achieved through the following technical solutions:
The disclosed novel plastics coated tube of the utility model comprises steel pipe, and described steel pipe is provided with large aperture end and small aperture end, and the place is provided with interior male structure at the large aperture end, is respectively equipped with anticorrosive coat first and anticorrosive coat second at the inner and outer wall of steel pipe.Interior male structure is convenient to fix when mounted the position of the end to end plastics coated tube of two joints, and inside and outside corrosion-inhibiting coating first and anticorrosive coat second have guaranteed the plastics coated tube good anti-corrosion.
Compared with prior art, the beneficial effects of the utility model are:
1, pass through to adopt the plastics coated tube of internal and external anti-corrosive coating, traditional tubing of comparing, its corrosion resistance prolongs, and is convenient to repair when external layer is damaged;
2, the disclosed plastics coated tube of the utility model, use simple, easy for installation, the working efficiency when raising pipeline that can be indirect is installed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, steel pipe; 2, anticorrosive coat first; 3, anticorrosive coat second; 4, large aperture end; 5, small aperture end, 6, interior male structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, the utility model comprises steel pipe 1, and described steel pipe 1 is provided with large aperture end 4 and small aperture end 5, and male structure 6 in end 4 places in large aperture are provided with is respectively equipped with anticorrosive coat first 2 and anticorrosive coat second 3 at the inner and outer wall of steel pipe 1.Described anticorrosive coat first 2 and anticorrosive coat second 3 can be the corrosion-inhibiting coating of same material, also can adopt the corrosion-inhibiting coating of different materials, all adopt polyethylene or the epoxide resin material that meets the state health standards performance as the preferred anticorrosive coat first 2 of the utility model and anticorrosive coat second 3.
When production and processing, guarantee that the corrosion-inhibiting coating of novel plastics coated tube covers evenly, because anticorrosive paint self makes that the anticorrosion time limit is promoted; During use, two plastics coated tubes join end to end, the small aperture end 5 of a plastics coated tube is placed in the large aperture end 6 of another root plastics coated tube, under the effect of the interior male structure 6 of large aperture end 4, make the fixed-site of two plastics coated tubes, because the matching relationship between the internal orifice dimension of large aperture end 4 and the outer aperture of small aperture end 5 has guaranteed convenience and the sealing of installing, the installation back only need carry out simple preservative treatment and encapsulation process gets final product.
