Abstract

The utility model provides a novel ERW seamless nanometer composite pipe, which relates to a pipe, in particular relates to an ERW seamless composite pipe. The ERW seamless composite pipe comprises a metal pipe body (1) and an outer adhesive layer (2), and also comprises an outer anti-ultraviolet nanometer micro-sphere plastic layer (3) and an outer nanometer micro-sphere plastic layer (4), the outer adhesive layer (2) at the outer side of the metal pipe body (1), the outer anti-ultraviolet nanometer micro-sphere plastic layer (3) and the outer nanometer micro-sphere plastic layer (4) are arranged in sequence. The nanometer micro-sphere plastic layer adopts the structure that nanometer micro-spheres are added into the prior plastic stable molecule structure, thus intensity and the hardness of the plastic layer are greatly enhanced, the use range of the novel ERW seamless nanometer composite pipe is enlarged, and the novel ERW seamless nanometer composite pipe is particularly applied to oil pipelines and large-scale pipelines. The utility model has the advantages that the pipe is corrosion resistant, the service life is long, the intensity is high, the outer composite layer is not easy to be damaged, and the like.

Description

New E RW seamless process nano composited tube

Technical field:

The utility model relates to a kind of pipe, is specifically related to a kind of ERW seamless multiple tube.

Background technique:

At present, the fluid-transporting tubing that uses in fields such as draining, chemical industry, mining, oil drilling, electronics, agriculturals, great majority adopt common steel tube, Coating Steel Pipe or plastic pvc tubing, but in these pipelines, the easy burn into of common steel tube is short working life; Steel pipe zinc-plated or the increase anticorrosive paint comes off easily owing to coating, does not still have to solve the problem of corrosion easily; The plastic pvc material is because the hardness of itself is not enough, and application area is very restricted, and is blocked easily.

Chinese patent ZL03262835.8 discloses a kind of ageing-resistant steel-plastic composite pipe, and this kind steel pipe has solved a lot of problems, has improved the corrosion resistance of steel pipe, has prolonged the working life of steel pipe; This kind steel pipe is to increase in the outside of common steel tube or Coating Steel Pipe the plastics composite bed is arranged; this composite bed has protected tubing to be difficult for being corroded really; also prolonged the working life of tubing; but because the characteristic of outer layer plastic itself; the hardness of plastics itself is not enough; make application area be restricted; particularly petroleum pipeline field and large-scale pipeline; because the weight of large-scale pipeline own is big; outer composite plastic often just is damaged in the way in transportation, carrying, institute so that at a lot of fields steel-plastic composite pipe owing to characteristic own is limited.

The model utility content:

The purpose of this utility model provides a kind of new E RW seamless process nano composited tube, and it has corrosion-resistant, long service life, intensity height, outside composite bed and is difficult for advantages such as destroyed.In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises metal body 1, outer adhesive layer 2, it also comprises outer antiultraviolet nano microsphere plastic layer 3, outer nano microsphere plastic layer 4, is arranged in order between the outer adhesive layer 2 in metal body 1 outside, outer antiultraviolet nano microsphere plastic layer 3, the outer nano microsphere plastic layer 4.The nano microsphere plastic layer is to add nano microsphere in existing plastics stable molecular structure, makes the intensity of plastic layer and hardness be greatly improved, and makes the utility model enlarge using scope, particularly is applicable to the application of petroleum pipeline, large-scale pipeline.The utlity model has corrosion-resistant, long service life, intensity height, outside composite bed and be difficult for advantages such as destroyed.

Description of drawings:

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the structural representation of nano microsphere 10 in the embodiment one, and Fig. 3 is the structural representation of embodiment two, and Fig. 4 is the structural representation of embodiment three.

Embodiment:

Embodiment one, form by metal body 1, outer adhesive layer 2, outer antiultraviolet nano microsphere plastic layer 3, outer nano microsphere plastic layer 4 referring to this embodiment of Fig. 1, be arranged in order between the outer adhesive layer 2 in metal body 1 outside, outer antiultraviolet nano microsphere plastic layer 3, the outer nano microsphere plastic layer 4.Referring to Fig. 2, the nano microsphere plastic layer is to add nano microsphere 10 in existing plastics stable molecular structure 9, nano microsphere can be so that the intensity of plastic layer and hardness be greatly improved, make the outer antiultraviolet nano microsphere plastic layer 3 in the pipeline outside, the hardness and the intensity of outer nano microsphere plastic layer 4 be improved, the composite plastic layer in the outside is difficult for destroyed, make the utility model enlarge using scope, particularly be applicable to the application of petroleum pipeline, large-scale pipeline.

Embodiment two, be that with the difference of embodiment one inboard of metal body 1 is provided with inner binder layer 5, inner plastic layer 6 referring to this concrete enforcement of Fig. 3, inner binder layer 5 is arranged on the internal surface of metal body 1, and the inboard of inner binder layer 5 is provided with and inner plastic layer 6.Because what flow in the body generally all is fluid, do not have bigger bump or action of gravity, so the body inboard does not need to adopt nano microsphere plastic layer and antiultraviolet nano microsphere plastic layer, and adopt common plastic layer to get final product, both etch-proof effect can be played, production, application cost can also be reduced.Other composition is identical with embodiment one with annexation.

Embodiment three is to be coated with external galvanized layer layer 7 between metal pipe 1 and the outer adhesive layer 2 referring to the difference of this embodiment of Fig. 4 and embodiment one.Increase external galvanized layer layer 7 and can further improve the intensity and the hardness of tubing, and improved anti-corrosion capability.Other composition is identical with embodiment one with annexation.
