Background
At present, the anticorrosion structure of the steel-plastic conversion pipe fitting has the following defects: under the condition of long-term underground burying, the corrosion-resistant coating has weak tolerance to electrolyte soaking, relatively short corrosion-resistant effective period, poor self strength of a corrosion-resistant layer, intolerance to extrusion, collision and abrasion of hard sharp objects, weather resistance problem of the exposed ground part, peeling and chapping of the exposed ground part and the like caused by thermal expansion and cold contraction, and aging under ultraviolet irradiation.
Disclosure of Invention
To the weak point among the prior art, the utility model provides a conversion pipe fitting is moulded to anticorrosive steel of polyurea.
In order to achieve the above purpose, the utility model discloses technical scheme as follows:
the utility model provides a conversion pipe fitting is moulded to anticorrosive steel of polyurea, includes the pipe fitting body, the pipe fitting body includes steel pipe, PE pipe, lock hoop and polyurea layer, steel pipe one end with PE pipe one end is connected with the extrusion insertion mode, and is connected overlap department surface at PE pipe and steel pipe and adds the lock hoop, polyurea layer parcel cover in the steel pipe the lock hoop with the whole surface that PE union coupling constitutes to guarantee whole leakproofness.
Further, the steel pipe is divided into a straight pipe and a bent pipe.
Has the advantages that: the utility model discloses a conversion pipe fitting corrosion resisting property is excellent, and the environmental protection is pollution-free to the anticorrosive steel of polyurea.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.
Fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.
In the figure, 1-pipe fitting body, 2-locking hoop, 3-polyurea layer, 4-steel pipe and 5-PE pipe.
Detailed Description
The present invention is described below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
Example 1
