Abstract
The utility model relates to an acid-resistant pipeline consisting of stainless steel pipelines, a carbon steel pipeline, a stainless steel mesh, and anti-corrosion plastics, wherein, the stainless steel pipelines are welded at the two ends of the carbon steel pipeline; and a layer of stainless steel mesh is arranged on the inner wall of the part, though which the stainless steel pipeline is welded with the carbon steel pipeline. The method of rolling a corrosion-resistant plastic layer on the inner wall of the carbon steel pipeline and the stainless steel mesh can realize the following advantages: the carbon steel pipeline can be used for effectively replacing the stainless steel pipeline and transporting acid liquid, so that the purpose of saving the production cost is achieved.
Description
Technical field:
The utility model relates to a kind of pipeline, particularly relates to a kind of acidproof pipeline that is used to carry acidic liquid.
Background technique:
In industrial processes; utilize a large amount of acidic liquid of line transportation through regular meeting; and the pipeline that uses often adopts is the pipeline that stainless steel is made; though stainless steel pipeline has good corrosion resistance; but cost of production is higher on the one hand, and also exists the defective of processing difficulties on the other hand.
Summary of the invention:
The purpose of this utility model will provide a kind of acidproof pipeline exactly, and it can fundamentally overcome the existing defective of Vintage Product, reduces production costs significantly, improves the performance of product.The purpose of this utility model is to realize like this, it is made up of a kind of acidproof pipeline Stainless Steel Tube, carbon steel piping, Stainless Steel Cloth, corrosion resistant plastics, it is characterized in that: at the two ends of carbon steel piping soldering stainless steel pipeline, inwall at stainless steel pipeline and carbon steel piping weld is provided with one deck Stainless Steel Cloth, rolls lining one corrosion resistant plastic layer at described carbon steel piping inwall and the online heating of Stainless Steel Wire.The utlity model has simple in structure, convenient welding, characteristics such as cost of production is low.
Description of drawings:
Fig. 1 is the utility model structural representation
1, Stainless Steel Tube 2, Stainless Steel Cloth 3, corrosion resistant plastics 4, carbon steel piping
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail in the drawings, a kind of corrosion resistant pipeline of the utility model is made up of Stainless Steel Tube, carbon steel piping, Stainless Steel Cloth, corrosion resistant plastics, it is characterized in that: at the two ends of carbon steel piping soldering stainless steel pipeline, inwall at stainless steel pipeline and carbon steel piping weld is provided with one deck Stainless Steel Cloth, rolls lining one corrosion resistant plastic layer at described carbon steel piping inwall and the online heating of Stainless Steel Wire.During concrete enforcement, at the two ends of carbon steel piping difference soldering stainless steel pipeline, weld one deck Stainless Steel Cloth then again on the inwall of weld, the method that adopts heating to roll lining on Stainless Steel Cloth and carbon steel piping inwall covers one deck corrosion resistant plastics.Like this,, can solve the problem of pipeline corrosion resistant effectively, adopt carbon steel piping can obtain and adopt the same effect of stainless steel pipeline conveying equally because covered one deck corrosion resistant plastics at the inwall of carbon steel piping.Simultaneously since within it wall be provided with one deck Stainless Steel Cloth, can make the corrosion resistant plastics that cover on it, more firm, be not easy to come off, and can be attached to more tightly on the carbon steel piping inwall.The utility model is simple in structure, can replace stainless steel pipeline with carbon steel, thereby can reduce production costs significantly.
