Abstract
The utility model provides a compound metal corrugated pipe, which includes peaks and troughs composed of an external layer, a middle layer and an internal layer; the external layer and the middle layer are made of 316 stainless steel; and the internal layer is made of 254SMO stainless steel. The utility model achieves the advantages of simple product structure, excellent sea water corrosion resistance and long service life.
Description
Technical field
The utility model relates to a kind of bellows, especially a kind of composition metal bellows.
Background technique
Use the metal bellows at seawater pipeline at present, generally adopt 316 stainless steel materials, but there is point corrosion in 316 stainless steels in seawater, working life is short.Domestic also have the 254SMO of employing stainless steel as the bellows material, though sea water corrosion resistant is good, price is too expensive, and the general user holds and can't stand.
Summary of the invention
In order to overcome not seawater corrosion resistance of existing 316 corrugated stainless steel tubings, working life is short, the deficiency that 254SMO corrugated stainless steel tubing price is too expensive, and the utility model provides a kind of composition metal bellows.
The technological scheme that its technical problem that solves the utility model adopts is a kind of composition metal bellows, comprises crest, trough, is combined by skin, middle level and internal layer, and outer and middle layer material is 316 stainless steels, and inner layer material is the 254SMO stainless steel.
The beneficial effects of the utility model are that product structure is simple, and sea water corrosion resistant is good, long service life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is embodiment's a tectonic maps;
Among the figure: 1. crest; 2. trough; 3. outer; 4. middle level; 5. internal layer.
Embodiment
As shown in Figure 1, a kind of composition metal bellows comprises crest 1, trough 2, is combined by skin 3, middle level 4 and internal layer 5, and skin 3 and middle level 4 materials are 316 stainless steels, and internal layer 5 materials are the 254SMO stainless steel.Adopt complex form, provide cost savings greatly.
Claims (1)
1. a composition metal bellows comprises crest, trough, is combined by skin, middle level and internal layer, it is characterized in that: described skin and middle layer material are 316 stainless steels, and described inner layer material is the 254SMO stainless steel.
