Abstract
The utility model discloses a metal pipe, including interior anticorrosive coating and outer anticorrosive coating, the inner wall and the outer wall of metal pipe are the rough surface of level, interior anticorrosive coating and outer anticorrosive coating set up the inboard and the outside at the metal pipe respectively, the surface of outer anticorrosive coating is equipped with the protective layer. The utility model discloses a surface at outer anticorrosive coating is provided with the protective layer, reasonable in design, simple structure, with low costs, and corrosion resisting property is strong, compressive strength is big, the abrasionproof decreases, has played the effect in extension tubular metal resonator life-span.
Description
Technical field:
The utility model relates to a kind of tubing, relates to particularly that a kind of antiseptic property is good, compressive strength is big, antiwear non-corrosive metal (NCM) pipe.
Background technique:
Using more metal tube on the existing market is interior composite pipe or metal composite pipe, nonmetal composite pipe, and they do not possess inside and outside antiseptic property simultaneously, do not exist the low problem of compressive strength; Not anti-wear yet, thus when construction, connection speed was slow, and efficient is low; Easy abrasion, the life-span is short etc.
For example the patent No. is 200720015381.6, and publication number is 201081074 Chinese patent " two composite anti-corrosive metal tube ".A kind of tubing is disclosed; Be particularly related to two composite anti-corrosive metal tubes that a kind of antiseptic property is good, compressive strength is big; Form by interior anticorrosive coat (1), external anti-corrosion layer (2); A fixing metal tube (3) between interior anticorrosive coat (1) and external anti-corrosion layer (2), metal tube (3) inside and outside wall is processed rugged pitted skin (4); The deficiency of this patent is: anticorrosion ability is general, and the surface is worn easily and cause the metal tube life-span short.
The model utility content:
The purpose of the utility model is to overcome the problems referred to above that metal tube exists in the existing technology, proposes a kind of metal tube.The surface that the utility model is employed in external anti-corrosion layer is provided with protective layer, and is reasonable in design, simple in structure, cost is low, and Corrosion Protection is strong, compressive strength is big, anti-wear, played the effect that prolongs the metal tube life-span.
The utility model adopts following technological scheme to realize:
A kind of metal tube; Anticorrosive coat and external anti-corrosion layer in comprising; The inner and outer wall of said metal tube is rugged pitted skin, it is characterized in that: anticorrosive coat and external anti-corrosion layer are separately positioned on the inboard and the outside of metal tube in said, and the surface of said external anti-corrosion layer is provided with protective layer.
Said protective layer is epoxy resin layer or skin of paint.
The advantage of the utility model is:
1, the utility model surface of being employed in external anti-corrosion layer is provided with protective layer, and is reasonable in design, simple in structure, cost is low, and Corrosion Protection is strong, compressive strength is big, anti-wear, played the effect that prolongs the metal tube life-span.
2, the utility model adopts epoxy resin layer or skin of paint as protective layer, and epoxy resin layer or skin of paint have further strengthened anticorrosive property, and the metal tube life-span obtains prolonging.
Description of drawings:
Fig. 1 is the utility model structural representation
Mark among the figure: 1, interior anticorrosive coat, 2, external anti-corrosion layer, 3, metal tube, 4, protective layer.
Embodiment:
Embodiment 1:
A kind of metal tube; Anticorrosive coat 1 and external anti-corrosion layer 2 in comprising; The inner and outer wall of said metal tube 3 is rugged pitted skin, and said interior anticorrosive coat 1 and external anti-corrosion layer 2 are separately positioned on the inboard and the outside of metal tube 3, and the surface of said external anti-corrosion layer 2 is provided with protective layer 4.
In the utility model, said protective layer 4 is an epoxy resin layer.
The product of the utility model in use; Adopt chemical industry to handle the inside and outside wall of metal tube 3 is processed rugged pitted skin; Being connected firmly of feasible interior anticorrosive coat 1 and external anti-corrosion layer 2 and metal tube, epoxy resin layer is further protected external anti-corrosion layer, and the metal tube life-span obtains prolonging.
Embodiment 2:
A kind of metal tube; Anticorrosive coat 1 and external anti-corrosion layer 2 in comprising; The inner and outer wall of said metal tube 3 is rugged pitted skin, and said interior anticorrosive coat 1 and external anti-corrosion layer 2 are separately positioned on the inboard and the outside of metal tube 3, and the surface of said external anti-corrosion layer 2 is provided with protective layer 4.
In the utility model, said protective layer 4 is a skin of paint.
