Abstract
The utility model relates to a corrosion-resistant composite pipe fitting and belongs to the technical field of pipe fittings. The pipe fitting is characterized in that: a base layer of pipe fitting (1) and a composite layer of pipe fitting (2) are arranged from outside to inside; the base layer of pipe fitting (1) is made from a 16 Mn steel pipe material; and the composite layer of pipe fitting (2) is made from an N10276 steel pipe material. The base layer of pipe fitting and the composite layer of pipe fitting are arranged from outside to inside, and the composite layer of pipe fitting is made from an N10276 steel pipe material, so that excellent corrosion resistance and stability of the corrosion resistance of the composite pipe fitting are ensured, the conveying safety of a medium with relatively high corrosion is ensured, and the service life is relatively long.
Description
Technical field
The utility model relates to a kind of pipe fitting, relates in particular to a kind of corrosion-resistant composite pipe fitting, is widely used in the fed sheet of a media of industries such as oil, chemical industry, electric power, belongs to the pipe fitting technical field.
Background technique
Before the utility model is made, traditional corrosion-resistant pipe fitting, pipe fitting basic unit is generally processed by the 16Mn steel pipe; To tube intracavity built-up welding N10276 material, this type pipe fitting cryogenic property is good then, can satisfy requirement of strength and reach basic anticorrosion effect; Therefore can only well be used for the conveying of general corrosion medium, but stronger, during the more abominable conveying of corrosive environment for corrosive medium; Because resurfacing welding material is corrosion-resistant relatively poor; And stability is very poor, causes pipe fitting lower working life, influences work safety.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provide a kind of corrosivity that is used for to carry, be fit to abominable corrosive environment than strong medium, and working life is than long corrosion-resistant composite pipe fitting.
The purpose of the utility model is achieved in that a kind of corrosion-resistant composite pipe fitting, from outer in be followed successively by basic unit's pipe fitting and clad pipe spare, said basic unit pipe fitting is processed by the 16Mn tube material, said clad pipe spare is processed by the N10276 tube material.
Compared with prior art, the beneficial effect of the utility model is:
The utility model since from outer in be followed successively by basic unit's pipe fitting and clad pipe spare; Clad pipe spare is processed by the N10276 tube material, make the corrosion resistance of N10276 bring into play fully, and erosion-resisting stability is very good; N10276 steel pipe itself has superior anti-corrosion capacity for different chemical environments simultaneously; Comprise ferric trichloride and dichloride copper, the foul solution (organic or inorganic) of heat, strong oxidizer such as formic acid, acetate, acetic anhydride and seawater, saline solution environment etc.; For pit corrosion and stress corrosion cracking outstanding drag is arranged all, simultaneously, it also is that minority can be born wet chlorine, hypochlorite, chlorine dioxide corrosive action.So that composite pipe fitting has excellent decay resistance, guaranteed corrosivity than the strong medium delivery safety, working life is longer.
