Abstract
The utility model provides a metal bellows comprising a crest and a trough and being formed by combining an outer layer, a middle layer and an inner layer, wherein the outer layer and the middle layer are made from 316 austenitic stainless steel, the inner layer is made from two phase stainless steel. The utility model has the beneficial effects of simple structure, excellent water sea corrosion resistance and long service life.
Description
Technical field
The utility model relates to a kind of bellows, especially a kind of metal bellows.
Background technique
Use the metal bellows at seawater pipeline at present, generally adopt 316 austenitic stainless steel materials, but there is point corrosion in 316 Austenitic Stainless Steels in seawater, working life is short.Domestic also have the two phase stainless steel of employing 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 austenite stainless corrugated steel pipes, working life is short, the deficiency that two-phase stainless corrugated steel pipe price is too expensive, and the utility model provides a kind of metal bellows.
The technological scheme that its technical problem that solves the utility model adopts is a kind of metal bellows, comprises crest, trough, is combined by skin, middle level and internal layer, and outer and middle layer material is an Austenitic Stainless Steel, and inner layer material is a two phase 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 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 Austenitic Stainless Steels, and internal layer 5 materials are two phase stainless steel.Adopt complex form, provide cost savings greatly.
Claims (1)
1. a 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 Austenitic Stainless Steel, and described inner layer material is a two phase stainless steel.
