Description
Technical field
The utility model is related to a kind of hot galvanized steel pipe.
Background technology
Hot dip galvanizing pipe is to make molten metal and iron-based precursor reactant and produce alloy-layer, so that both matrix and coating are combined.With the plating solution of melting complicated physics, chemical reaction occur for steel pipe matrix, form the corrosion resistant hard-packed iron alloy layer of zinc one.Alloy-layer combines together with pure zinc layer, steel pipe matrix.Therefore its corrosion resistance is strong.1st, the uniformity of zinc coat：Steel pipe sample continuous impregnate 5 times in copper-bath must not redden（Plate coppery）, 2, surface quality：The surface of coating steel pipe should have complete zinc coat, must not be with the presence of the blackspot and bubble not plated, it is allowed to the presence of little mat surface and local list edge.3rd, galvanizing layer weight：Required according to demander, coating steel pipe can make zinc layer weight measure, its average value should be not less than 500g/ square metres, and any of which sample cannot be less than 480g/ square metres, and regular galvanized pipe manufacturer, in order to ensure quality, can all use.Formally hereafter, the cold galvanizing pipe of filtering technique backwardness will ban the use of cold galvanizing Guan Zuoshui, gas pipe from now on for the current Ministry of Construction.Zinc layers above galvanized pipe are electrodeposited coatings, and zinc layers are independently layered with steel pipe matrix.Zinc layers are relatively thin, and zinc layers are simply attached on steel pipe matrix, are easily come off.Therefore its poor corrosion resistance.In New Dwelling, cold galvanizing steel pipe is prohibitted the use of as feed pipe.Known steel pipe inner wall and outer wall are not provided with zinc coat, it is used for internal circulation corrosive liquids or gas, or when for outside being arranged at corrosivity place, often occur steel pipe to be corroded, it is typically only capable to spray to corrode material just make it have corrosion resistance for the inner or outer wall of common metal body, therefore, many unnecessary expenses are also increased and also very big to the destruction of environment.
Utility model content
The purpose of this utility model is to provide a kind of with antisepsis, low expense, durable, weather-proof and environmentally friendly hot galvanized steel pipe.
The technical solution of the utility model is：A kind of hot galvanized steel pipe, the hot galvanized steel pipe includes steel cylindrical tube, the steel cylindrical tube is hollow, the side of the steel cylindrical tube is provided with slot, the steel cylindrical tube two ends are provided with several reinforcements, the steel cylindrical tube upper end is provided with hanger, and the surface of the steel cylindrical tube scribbles erosion-resisting zinc coat.
In one preferred embodiment of the utility model, the steel cylindrical tube is seamless steel pipe or resistance welding steel pipe.
In one preferred embodiment of the utility model, the number of the reinforcement is 10.
In one preferred embodiment of the utility model, the inwall of the steel cylindrical tube is also coated with erosion-resisting zinc coat.
In one preferred embodiment of the utility model, the thickness of the zinc coat is 20-30um.
A kind of hot galvanized steel pipe of the present utility model, with antisepsis, low expense, durable, it is weather-proof and environmentally friendly the characteristics of.
Brief description of the drawings
Accompanying drawing 1 is the dimensional structure diagram of the preferred embodiment of the utility model hot galvanized steel pipe one.
The mark of each part is as follows in accompanying drawing：1st, steel cylindrical tube, 2, reinforcement, 3, hanger.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the present utility model can be easier to be readily appreciated by one skilled in the art, apparent clearly defined so as to be made to protection domain of the present utility model.
Refer to Fig. 1, Fig. 1 is a kind of hot galvanized steel pipe of the utility model, the hot galvanized steel pipe includes steel cylindrical tube 1, the steel cylindrical tube 1 is hollow, the side of the steel cylindrical tube 1 is provided with slot, the two ends of steel cylindrical tube 1 are provided with several reinforcements 2, the upper end of steel cylindrical tube 1 is provided with hanger 3, the surface of the steel cylindrical tube 1 scribbles erosion-resisting zinc coat, the steel cylindrical tube 1 is seamless steel pipe or resistance welding steel pipe, the number of the reinforcement 2 is 10, the inwall of the steel cylindrical tube 1 is also coated with erosion-resisting zinc coat, the thickness of the zinc coat is 20-30um.
Further illustrate, the setting of the hanger is that staff slings for convenience.Hot dip galvanizing pipe is to make molten metal and iron-based precursor reactant and produce alloy-layer, so that both matrix and coating are combined.Galvanizing is that steel pipe first is carried out into pickling, in order to remove the iron oxide of steel tube surface, after pickling, by being cleaned in ammonium chloride or solder(ing)acid or ammonium chloride and zinc chloride mixed aqueous solution groove, is then fed into hot-dip tank.Galvanizing has coating uniform, and adhesive force is strong, the advantages of long service life.With the plating solution of melting complicated physics, chemical reaction occur for hot galvanized steel pipe matrix, form the corrosion resistant hard-packed iron alloy layer of zinc one.Alloy-layer combines together with pure zinc layer, steel pipe matrix.Therefore its corrosion resistance is strong.The utility model provides a kind of hot galvanized steel pipe, with antisepsis, low expense, durable, it is weather-proof and environmentally friendly the characteristics of.
Embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change or replacement that can be expected without creative work, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
