Abstract
The utility model relates to a steel pipe and particularly relates to a U-shaped stainless steel pipe comprising a U-shaped pipe body, wherein the cross section of the U-shaped pipe body is circular; and a first corrosion resistant layer is formed on the outer surface of the U-shaped pipe body, while a second corrosion resistant layer is formed on the outer surface of the U-shaped pipe body. Therefore, in the use process of the steel pipe, the first corrosion resistant layer and the second corrosion resistant layer are capable of isolating corrosive materials from the steel pipe, thereby achieving the effect of corrosion resistance; as a result, the steel pipe body is protected from being corroded by the corrosive materials and the service life of the steel pipe is prolonged; and in the use process, the steel pipe does not need to be replaced frequently, so that the production cost is reduced.
Description
Technical field
The utility model relates to a kind of steel pipe, is specifically related to a kind of U type Stainless Steel Tube.
Background technique
Stainless-steel pipe is a kind of rectangular circular steel of hollow, mainly is widely used in industrial conveyance conduit such as oil, chemical industry, medical treatment, food, light industry, machinery instrument and machine structural parts etc.Its shape is produced as required, like U type Stainless Steel Tube; Existing U type Stainless Steel Tube in use for some time, the phenomenon that its outer surface and internal surface will occur being corroded shortens working life of steel pipe, needs the frequent change steel pipe, has improved cost of production.
The model utility content
To above-mentioned technical problem, the utility model provides a kind of U type Stainless Steel Tube, and it can effectively prevent the problem that steel tube surface is corroded, and prolongs the working life of steel pipe, need not the frequent change steel pipe, reduces production costs.
The technological scheme that realizes the utility model is following:
U type Stainless Steel Tube, it comprises U type pipe body, and the shape of cross section of this U type pipe body is circular, and the outer surface of U type pipe body is provided with the first layer anti-corrosion layer, and the internal surface of U type pipe body is provided with second layer anti-corrosion layer.
The thickness of said first layer anti-corrosion layer, second layer anti-corrosion layer is between 2mm-5mm.
The thickness of said first layer anti-corrosion layer, second layer anti-corrosion layer is 3mm.
Said first layer anti-corrosion layer, second layer anti-corrosion layer are polytetrafluorethylecoatings coatings.
Adopted such scheme, be provided with the first layer anti-corrosion layer at the outer surface of U type pipe body, internal surface is provided with second layer anti-corrosion layer; In the steel pipe using process, first layer anti-corrosion layer, second layer anti-corrosion layer can be isolated corrosive material and steel pipe, play erosion-resisting effect like this; Thereby guarantee that steel tube body can not receive the corrosion of corrosive material, prolongs the working life of steel pipe, in use; Just need not the frequent change steel pipe, reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that A-A among Fig. 1 is to sectional view;
Among the figure, 1 is U type pipe body, and 2 is the first layer anti-corrosion layer, and 3 is second layer anti-corrosion layer.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Referring to Fig. 1,2, U type Stainless Steel Tube, it comprises U type pipe body 1, and the shape of cross section of this U type pipe body is circular, and the outer surface of U type pipe body 1 is provided with first layer anti-corrosion layer 2, and the internal surface of U type pipe body is provided with second layer anti-corrosion layer 3.Wherein, The thickness of first layer anti-corrosion layer, second layer anti-corrosion layer is between 2mm-5mm; In the concrete production process; The thickness of first layer anti-corrosion layer, second layer anti-corrosion layer can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, and the thickness of first layer anti-corrosion layer, second layer anti-corrosion layer can equate, and is also unequal.The first layer anti-corrosion layer is a polytetrafluorethylecoatings coatings, and second layer anti-corrosion layer also is a polytetrafluorethylecoatings coatings.
