Description
Technical field
The utility model relates to technique of pipe field, is specifically related to a kind of novel austenite-ferrite stainless steel pipe.
Background technique
Existing Stainless Steel Tube material is more, and majority is ferrite and austenite, and its plasticity of ferrite stainless steel pipe, toughness is on the low side, has brittleness at room temperature, and intergranular corrosion resistance performance and welding performance are all not high; Its intensity of Austenitic Stainless Steel, intergranular corrosion resistance and the stress corrosion performance of resistance to chloride are more weak; And the thinner thickness of existing Stainless Steel Tube, soundproof effect is poor, and when flowing medium passes through, noise is large, and shell is yielding, has a strong impact on and sells and use.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of reasonable in design, structure are simple, soundproof effect good, and shell is not yielding, the novel austenite-ferrite stainless steel pipe of long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of novel austenite-ferrite stainless steel pipe, comprise body, described body is from inside to outside successively by internal layer, ferrous alloy layer, puigging and outer composition, described ferrous alloy layer exterior edge face is provided with multiple glove groove, each glove groove built-in type is provided with noise insulation block, described noise insulation block is all wholely set with puigging interior edge face, described internal layer and skin all adopt austenite-ferrite stainless steel material to make, the thickness of described internal layer is 4mm, outer field thickness is 5mm, the thickness of ferrous alloy layer is 18mm.
By adopting technique scheme, internal layer and skin all adopt austenite-ferrite two phase stainless steel material to make, and easily manufactured, intensity is high, corrosion resistance and good, and shell is not yielding; And ferrous alloy layer between internal layer and skin and acoustical layer structure arrange rationally, ferrous alloy layer has good combination property, can reduce manufacture cost, and puigging can reduce noise greatly, and soundproof effect is good.
The utility model is set to further: all dark 8mm of described glove groove, and glove groove longitudinal section is all in fan-shaped, and the structure of described noise insulation block structure and glove groove matches, and the thickness of puigging is 2mm., and the thickness of noise insulation block is 8mm.By this setting, vibrational power flow is more reasonable, and soundproof effect is better.
The utility model is also set to further: described internal layer, ferrous alloy layer, puigging and skin are integrally formed structure by compound.By this setting, each layer connects compact, fixing reliable, long service life.
The utility model is also set to further: described noise insulation block is integrally formed structure with the glove groove of aligning by compound.By this setting, noise insulation block connects reliable.
The utility model is also set to further: described puigging and noise insulation block form by the manufacture of expanded polystyrene material.By this setting, soundproof effect is good, low cost of manufacture.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is more reasonable, and internal layer and skin all adopt austenite-ferrite two phase stainless steel material to make, and easily manufactured, intensity is high, corrosion resistance and good, and shell is not yielding; And ferrous alloy layer between internal layer and skin and acoustical layer structure arrange rationally, ferrous alloy layer has good combination property, can reduce manufacture cost, and puigging can reduce noise greatly, and soundproof effect is good.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
See Fig. 1, a kind of novel austenite-ferrite stainless steel pipe disclosed in the utility model, comprise body, described body is from inside to outside successively by internal layer 1, ferrous alloy layer 2, puigging 3 and outer 4 compositions, described ferrous alloy layer 2 exterior edge face is provided with multiple glove groove 21, each glove groove 21 built-in type is provided with noise insulation block 31, described noise insulation block 31 is all wholely set with puigging 3 interior edge face, described internal layer 1 and outer 4 all adopts austenite-ferrite two phase stainless steel material to make, the thickness of described internal layer 1 is 4mm, the thickness of outer 4 is 5mm, the thickness of ferrous alloy layer 2 is 18mm.
As preferably, exterior edge face is provided with 12 glove grooves 21 to the present embodiment ferrous alloy layer 2 altogether, and 12 glove grooves 21 are uniformly distributed around the body center of circle.
For making the utility model structure more reasonable, as preferably, the all dark 8mm of glove groove 21 described in the present embodiment, and glove groove 21 longitudinal section is all in fan-shaped, the structure of described noise insulation block 31 and the structure of glove groove 21 match, the thickness of puigging 3 is 2mm., and the thickness of noise insulation block 31 is 8mm.
Described internal layer 1, ferrous alloy layer 2, puigging 3 and outer 4 are integrally formed structure by compound.Described noise insulation block 31 and the glove groove 21 aimed at are by connecting and composing integrative-structure.
