Abstract
The utility model relates to a novel corrosion-resistant corrugated pipe which comprises a metal pipe body. A plastic layer 2mm in thickness is arranged on the inner wall of the pipe body. Direct contact of delivery media with the pipe body can be avoided by the aid of the plastic layer arranged on the inner wall of the metal pipe body, so that the novel corrosion-resistant corrugated pipe is high in corrosion resistance and long in service life.
Description
Technical field
The utility model relates to a kind of bellows, is specifically related to have the corrosion-resistant bellows of plastic layer, belongs to the tubing technical field.
Background technique
The bellows of existing technology mainly contains two types of plastic, rubber bellows and metal bellowss.And metal bellows is difficult for wearing out owing to have sound construction, plurality of advantages such as long service life, and it has progressively replaced the plastic, rubber bellows.
Yet metal bellows also exists the some shortcomings part, and it is vulnerable to the corrosion of fed sheet of a media after long-term the use, and especially when carrying the stronger medium of corrosivity, corrosion phenomenon is more obvious.
Therefore, for solving the problems of the technologies described above, the necessary bellows that a kind of novel corrosion resistant is provided is to overcome said defective of the prior art.
The model utility content
For addressing the above problem, the purpose of the utility model is to provide a kind of user cost low, and the bellows with excellent corrosion resisting performance.
Be to realize above-mentioned purpose, the technological scheme that the utility model is taked is: the novel corrosion resistant bellows, and it comprises a metallic body, is provided with one deck plastic layer in the inwall of said body, the thickness of this plastic layer is 2mm.
The novel corrosion resistant bellows of the utility model further is set to: said plastic layer is specially the PE plastic layer.
Compared with prior art; The utlity model has following beneficial effect: the corrosion-resistant bellows of the utility model is provided with one deck plastic layer through the inwall at the metal body; Thereby avoided fed sheet of a media directly to contact, made the anti-decay resistance of this bellows better, long service life with body.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
See also shown in the Figure of description 1, the novel corrosion resistant bellows comprises a metallic body 1, the profile undulate structure of this body 1.
The greatest improvement part of the bellows of the utility model is: the inwall in said body 1 is provided with one deck plastic layer 2, and the thickness of this plastic layer 2 is 2mm, and it is specially the PE plastic layer.
The corrosion-resistant bellows of the utility model is provided with one deck plastic layer 2 through the inwall at metallic body 1, thereby has avoided fed sheet of a media directly to contact with body, makes the anti-decay resistance of this bellows better, long service life.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
1. novel corrosion resistant bellows is characterized in that: comprise a metallic body, be provided with one deck plastic layer in the inwall of said body, the thickness of this plastic layer is 2mm.
2. novel corrosion resistant bellows as claimed in claim 1 is characterized in that: said plastic layer is specially the PE plastic layer.
