Abstract
The utility model discloses a corrosion-resistant bimetal composite concentric and eccentric reducing pipe, which comprises a corrosion-resistant alloy liner pipe and a carbon steel or alloy steel base pipe sleeved outside the liner pipe. The utility model has simple structure, and can maintain the pressure resistance and the corrosion resistance and simultaneously reduce the product cost significantly. Therefore, the utility model has the advantages of low cost, strong pressure resistance, strong corrosion- resistance and convenient connection with metal pipelines.
Description
Technical field
The utility model relates to a kind of composite bimetal pipe, is specifically related to the compound concentric and eccentric reducer of a kind of corrosion-resistant dual metal.
Background technique
At present, existing reducer pipe fitting mostly is single material greatly, perhaps adopts carbon steel or adopts stainless steel as material.In use have following shortcoming respectively: carbon steel reducer bearing capacity is strong, low price, but perishable; Though the stainless steel reducer is corrosion-resistant, bearing capacity is weak and cost an arm and a leg.Although the at present existing compound reducer that adopts pottery or plastic inner lining, to be connected difficulty very big with metal pipe line, is not suitable for using in metal pipe line.
The model utility content
The purpose of this utility model is at above-mentioned deficiency of the prior art, provide a kind of corrosion-resistant dual metal compound concentric and eccentric reducer, its simple in structure, withstand voltage corrosion resistance is strong, when being connected with the metal pipe line realization is convenient, also can reduce product cost greatly.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of corrosion-resistant dual metal is compound with one heart and eccentric reducer, it is characterized in that: described corrosion-resistant dual metal compound with one heart and eccentric reducer by corrosion resisting alloy system internal lining pipe be sleeved on carbon steel or alloy steel parent tube composition outside the internal lining pipe.
Described internal lining pipe and parent tube mesh together with hydraulic pressure or air pressure pressurization complex method.
The wall thickness of described internal lining pipe is not more than 5mm.
Described internal lining pipe is stainless steel, titanium alloy or Cuprum alloy.
The utility model compared with prior art has the advantage of carbon steel and alloyed steel concurrently, has following excellent beneficial effect: 1, good corrosion resistance, and what its internal lining pipe adopted is anti-corrosive alloy material; 2, bearing capacity is strong, and its parent tube adopts has high-intensity carbon steel material; 3, cheap, the utility model can replace expensive Stainless Steel Tube and can save 1/2 expense, thereby greatly reduces cost of material.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
The compound Concentric Reducers of a kind of corrosion-resistant dual metal as shown in Figure 1 and a kind of corrosion-resistant dual metal composite eccentric reducer are as shown in Figure 2 formed by corrosion resisting alloy system internal lining pipe 2 and the carbon steel or the alloy steel parent tubes 1 that are sleeved on outside the internal lining pipe 2.In the present embodiment, the wall thickness of internal lining pipe 2 generally is not more than 5mm, but the wall than parent tube 1 is thin, and internal lining pipe 2 and parent tube 1 mesh together with hydraulic pressure or air pressure pressurization complex method, wherein, internal lining pipe 2 can be stainless steel, titanium alloy or Cuprum alloy, and parent tube 1 can be used for the carbon steel or the alloyed steel of FLUID TRANSPORTATION for GB or oil, chemical industry standard-required.In actual processing and making process, earlier carbon steel or alloyed steel reducer are adopted casting, technology such as drawing and forging is made parent tube 1, then thin-walled corrosion resisting alloy pipe is adopted punching press, roll, technologies such as welding or cold hobbing are made internal lining pipe 2, again parent tube 1 and the internal lining pipe of making 2 carried out corresponding heat treatment, then the elbow of parent tube 1 and internal lining pipe 2 is assembled and be put in the mold tooling, adopt hydraulic pressure or air pressure mode that internal lining pipe 2 is pressurizeed, internal lining pipe 2 pressurized bulgings produce plastic deformation, resiliently deformable takes place in parent tube 1 simultaneously, make parent tube 1 fit tightly and be in the same place, after end finishing moulding with internal lining pipe 2.The corrosion-resistant dual metal of moulding compound physical dimension, tolerance and mechanical property concentric and eccentric reducer all reach the reducing fittings requirement of GB12459-2005 defined, the decay resistance requirement of lining alloy material in decay resistance reaches.
To sum up, carbon steel or alloy steel parent tube 1 bearing capacity are strong, low price; And internal lining pipe 2 itself has the advantage of excellent in toughness, weldability and corrosion resistance that Stainless Steel Alloy has.Thereby the utility model has the advantage of carbon steel and alloyed steel concurrently, is applicable to the composite bimetal pipe pipeline construction and is lower than under 200 ℃ of environment Korrosionsmedium to carry and can be used widely in application.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
