Abstract
The utility model provides an abrasion-resistant composite pipe for conveying slurry and belongs to the technical field of composite pipes. The abrasion-resistant composite pipe for conveying the slurry comprises a composite pipe body and steel flange heads which are arranged at two ends of the composite pipe body. The composite pipe body is in a three-layer composite structure of an inner layer, a middle layer, and an outer layer. The inner layer is an abrasion-resistant layer, the middle layer is a seepage-resistant layer, and the outer layer is a glass fiber reinforced layer. The abrasion-resistant layer is adopted as the inner layer, so corrosion resistance performance and abrasion resistance performance of a pipe are increased. The seepage-resistant layer is arranged in the middle, so slurry seepage can be effectively prevented. The glass fiber reinforced layer is adopted by the outer layer and effects of strength and stiffness can be provided. The abrasion-resistant performance of the abrasion-resistant composite pipe for conveying the slurry is two times the abrasion-resistant performance of a steel pipe, service life of a pipeline is prolonged, and cost is saved. The abrasion-resistant composite pipe is lighter than the steel pipe which is in the same specification with the pipe and is convenient to mount and carry.
Description
Technical field
The utility model belongs to the composite pipe technical field, is specifically related to a kind of slurry that is mainly used in the industry such as coloured, metallurgical, coal and dredging and mining field and carries the Antiwear composite pipe material of use.
Background technique
Along with the development of pipe long-distance slurry conveying technology, replace original vehicle borne mode with pipeline, reduced production and operation cost for the slurry conveying in the fields such as ore dressing, dredging, improve working efficiency and saved the energy.Simultaneously along with upgrading transition of China industry manufacturing enterprise, and the proposition of environmental protection construction, also there is huge market potential at the pipeline of this technical field.On the pipeline kind, what majority adopted is steel pipe, cast iron tube, has serious corrosion and wear problem at present, and pipeline is short working life, and the engineering maintenance expense is high.Some composite pipes, as ceramic composite pipe, special type abrasion resistant alloy pipe, Stainless Steel Tube, though have wear resistance preferably, the cost cost is higher.Various nonmetal pipelines such as sebific duct, ultrahigh molecular weight polyethylene tubing also rise in this field gradually in recent years, the anticorrosive anti-wear of pipeline increases, but because surface hardness is lower, the slurry that contains sharp edges in, fed sheet of a media fast for flow velocity, can not satisfy flexibly various operating mode needs, especially make bigbore wear-resistant pipe, rigidity and intensity can not satisfy the demands.In order to address the above problem, each pipeline producer has developed a series of Novel composite pipe one after another.As mentioning at steel pipe inner wall every certain distance in patent CN2545161Y composite wear-resistant slurry conveying pipe; fix a wear ring; the minority material is stopped the formation liner; utilize material itself to form protective layer; extend pipeline working life; but this design has reduced the latus rectum of tubing, thereby has affected the conveying capacity of pipeline.Patent CN2771611Y steel is moulded complex abrasion-proof, and by improving wear resistance and the corrosion resistance of tubing at inner lining of steel pipe ultra-high polyethylene tubing, but the moulding difficulty of pipeline is large, and technology controlling and process does not with great difficulty cause inner and outer pipes to separate, and pipe is scrapped.
The model utility content
The defects that exists in order to overcome prior art, the purpose of this utility model just is to provide a kind ofly not only to have been had wear resistance but also had had the slurry of economic and practical to carry the Antiwear composite pipe material of use, and it is mainly used in the industrial and mining fields such as coloured, metallurgical, coal and dredging.
Described a kind of slurry is carried the Antiwear composite pipe material of use, comprise the composite pipe body and be equipped with steel flange head at composite pipe body two ends, it is characterized in that the three-layer composite structure of described composite pipe body for being consisted of by internal layer, mesosphere and skin, described internal layer is wearing layer, the mesosphere is anti-leakage layer, glass outer steel enhancement layer.
Described a kind of slurry is carried the Antiwear composite pipe material of use, it is characterized in that described composite pipe body thickness is 16-20mm.
Above-mentioned a kind of slurry is carried the Antiwear composite pipe material of use, comprise the composite pipe body and be equipped with steel flange head at composite pipe body two ends, the three-layer composite structure of composite pipe body for being consisted of by internal layer, mesosphere and skin, internal layer is wearing layer, the mesosphere is anti-leakage layer, glass outer steel enhancement layer.Tubing body of the present utility model is by adopting wearing layer to be made as internal layer, increase the corrosion-resistant and wear-resisting property of tubing, the centre arranges anti-leakage layer, can effectively prevent the slurry seepage, the outer glass fibre reinforced plastics enhancement layer that adopts provides intensity and stiffness, and wear resistance of the present utility model is 2 times of steel pipe, extend the working life of pipeline, saved cost; And equal size pipe weight ratio steel pipe is light, is convenient to install carrying.

Embodiment
In order to further describe the utility model, below in conjunction with Figure of description, it is elaborated:
as shown in Fig. 1-2, a kind of slurry is carried the Antiwear composite pipe material of use, comprise composite pipe body 1 and be equipped with steel flange head 2 at composite pipe body 1 two ends, described composite pipe body 1 thickness is 16-20mm, be preferably 18 mm, it is three-layer composite structure, by internal layer 101, mesosphere 102 and outer 103 consists of, described internal layer 101 is wearing layer, it is prepared from by wear resistant filler and Special Resin mixture, described Special Resin is epoxy resin etc., mesosphere 102 is anti-leakage layer, it is that common unsaturated resin infiltrates the surperficial felt that reinforcing material forms, wherein unsaturated resin content is greater than 80%, outer 103 glass fibre reinforced plastics enhancement layers provide intensity and stiffness, are controlled by microcomputer that glass fiber yarn is Wrapping formed to be obtained.
After make in the internal layer 101 of composite pipe body 1 of the present utility model and mesosphere 102, outer 103 are wrapped in mesosphere 102 outside moulding by microcomputer control glass fiber yarn obtains, after composite pipe body 1 completes, two ends put steel flange head 2 and get final product, and steel flange head 2 is used for the connection of pipeline.
The beneficial effects of the utility model comprise: adopt unsaturated resin to make, pipeline is corrosion-resistant; The wear resistance of wear resistant filler is 2 times of steel pipe, has extended the working life of pipeline, has saved cost; Equal size pipeline weight ratio steel pipe is light, is convenient to install carrying.
