Abstract
The utility model discloses a steel plastic composite pipe, which comprises a metal pipe body 1 and an outer plastic layer 2. The outer plastic layer 2 is covered on the outer surface of the metal pipe body 1. The steel plastic composite pipe is used for fluid transportation of fields of water supply and discharge, a chemical industry, mining, electronic, agriculture, etc. The steel plastic composite pipe has corrosion resistance, light weight, smooth surface beautiful appearance, low cost, and long service life. The wall thickness of the metal pipe body is only half the wall thickness of the common steel pipe.
Description
The utility model relates to a kind of pipe, more specifically to a kind of composite pipe that is used for field conveyance fluids such as plumbing, chemical industry, mining, electronics, agricultural.
At present, the fluid-transporting tubing that uses in fields such as plumbing, chemical industry, mining, electronics, agriculturals, the one, adopt common steel tube, this steel pipe is easy to corrosion, and working life is short; The 2nd, adopt Coating Steel Pipe or steel tube surface to coat anticorrosive paint, because coating or coating be easy to come off, still can not fine solution etching problem; The 3rd, adopt plastic tube, this kind tubing is easily blocked.Aforementioned tubes because working life is short, fragile, is changed frequently, and influence is produced and operation.
The purpose of this utility model is to provide a kind of structure rational steel-plastic composite pipe that more becomes, and it not only has higher corrosion resistance, and intensity height, light weight, and cost of production is low, long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of steel-plastic composite pipe, comprise metal body 1, outer plastic layer 2, and outer plastic layer 2 covers metal body 1 outer surface.Above-mentioned metal body 1 can be F steel, Q195 steel, Q215 steel, Q235 steel, and above-mentioned outer plastic layer 2 can be polyvinyl plastics.
Above-mentioned metal body 1 internal surface can be equipped with inner plastic layer 3; Above-mentioned metal body 1 outer surface can be equipped with external galvanized layer layer 4, and above-mentioned metal body 1 internal surface can be equipped with interior zinc coat 5; Above-mentioned external galvanized layer layer 4 surface can be equipped with outer plastic layer 2, and above-mentioned interior zinc coat 5 surfaces can be equipped with inner plastic layer 3, and above-mentioned inner plastic layer 3 can be polyvinyl plastics.
Compared with prior art, the utlity model has following advantage:
1, the metal tube surface is equipped with plastic layer, and smooth surface is attractive in appearance;
2, the metal tube surface is equipped with plastic layer, and is corrosion-resistant, long service life;
3, plastic layer is built-in with the metal body, and pipe fitting has intensity preferably, is difficult for blocking;
4, the metal tube body thickness is about half of common steel tube in the steel-plastic composite pipe, light weight, and cost is low.
Below in conjunction with accompanying drawing the utility model is further described.
