Abstract
The utility model relates to a galvanized pipe, in particular to a galvanized pipe used for a condenser pipeline. The galvanized pipe is provided with a pipe body and a galvanizing coating attached to the pipe body, wherein, the thickness of the galvanizing coating is 5 to 7 microns, and a passivating film is arranged on the surface of the galvanizing coating, thereby solving the problem of poor corrosion resistance of the prior galvanized pipe. Due to the adoption of the thickness structure, the corrosion resistance can be enhanced, meanwhile, the passivating film is adopt to enhance the corrosion resistance of the galvanized pipe in the salt mist and to prolong the time for corrosion resistance.
Description
Technical field
The utility model relates to galvanized pipe, relates in particular to a kind of galvanized pipe that condenser pipe is used that is used for.
Background technique
The general-purpose thick of zinc coat of condenser pipe that is applied to the refrigerator refrigerator is less than 5 microns, and in use general easy being corroded can not reach the purpose of long-term use, poor corrosion resistance.
The model utility content
The technical problems to be solved in the utility model is: the problem of existing galvanized pipe poor corrosion resistance provides a kind of decay resistance strong galvanized pipe.
In order to overcome the defective that exists in the background technique, the utility model solves the technological scheme that its technical problem adopts and is: a kind of galvanized pipe has body and attached to the zinc coat on the body, the thickness of zinc coat is 5～7 microns.
There is passivating layer on zinc coat surface in the utility model, and passivating layer can be crossed anticorrosive effectively.
Zinc coat described in the utility model is electroplated the compactness height of made zinc coat, corrosion resistance and good for electroplating the zinc coat of making.
The utility model has solved the defective that exists in the background technique, and the thickness structure that adopts in the utility model is to improve corrosion resistance, has adopted passivating film to increase galvanized pipe anti-corrosion capacity in salt fog simultaneously, prolongs the corrosion resistant time.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the tangent plane structural representation of preferred embodiment of the present utility model;
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Galvanized pipe shown in Fig. 1, body 1 are that the steel that adopts is made, the diameter 1cm of body, and the body surface is by electroplating the fine and close zinc coat 2 of emerging one-tenth 6 micron thickness, at the outer surface of zinc coat passivating film 3 arranged, and passivating film 3 adopts and contains the chromium passivating spraying and make.
The galvanized pipe of making was not sealing salt spray resistance 120～150 hours.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (3)
