Abstract
The utility model relates to a kind of stainless steel composite pipes suitable for high-temperature medium conveying, including stainless steel layer, insulating layer and carbon steel layer, stainless steel layer, insulating layer and the carbon steel layer is set gradually from the inside to the outside, it is characterized by: the stainless steel layer is made of integrally formed flat segments and bellows segment, flat segments and bellows segment are uniformly at intervals.Design is scientific and reasonable for the utility model, has the advantages that reduction explosion probability, safe and reliable, reduction lose, are easily achieved, is a kind of stainless steel composite pipe with higher innovation.
Description
Technical field
The utility model belongs to multiple tube manufacture field, is related to a kind of stainless steel composite pipe, and in particular to one kind is applicable in
In the stainless steel composite pipe of high-temperature medium conveying.
Background technique
Stainless steel composite pipe by stainless steel and two kinds of metal materials of structural carbon steel using non-destructive pressure synchronize be combined into
New material has both the anticorrosive wear-resisting and brilliant appearance of stainless steel and the good bending strength of carbon steel and impact resistance, often quilt
It is used as water delivery, gas pipeline uses.
But when the medium of conveying is hot water or hot steam, certain dilatancy inevitably occurs for pipeline,
If things go on like this, there will be the security risk of explosion, not only cause any property loss, more likely injure life security.Therefore,
Invent it is a kind of suitable for high-temperature medium conveying, reduce explosion probability, safe and reliable stainless steel composite pipe be very it is necessary to
's.
By the retrieval to patent document, patent document identical with present patent application is not found.
Summary of the invention
The purpose of this utility model is to provide a kind of scientific structure designs rationally, reduces explosion probability, is safe and reliable, drop
Low loss, the stainless steel composite pipe for being suitable for high-temperature medium conveying being easily achieved.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of stainless steel composite pipe suitable for high-temperature medium conveying, including stainless steel layer, insulating layer and carbon steel layer, institute
Stainless steel layer, insulating layer and the carbon steel layer stated are set gradually from the inside to the outside, it is characterised in that: the stainless steel layer by one at
The flat segments and bellows segment of type are constituted, and flat segments and bellows segment are uniformly at intervals.
Moreover, the outer surface of the bellows segment and the outer surface flush of flat segments.
Moreover, further including stainless steel lining, stainless steel lining is provided between the stainless steel layer and insulating layer.
It the advantages of the utility model and has the beneficial effect that
1, this stainless steel composite pipe for being suitable for high-temperature medium conveying can by the setting of bellows segment on stainless steel layer
It effectively avoids keeping pressure excessive because being heated in pipeline with the ability using its deformation, thus the problem of expansion is burst.When in pipeline
When the medium overheat of conveying, stainless steel layer passes through the deformation of bellows segment thereon, to reach increase space, pipe expansion is avoided to burst
Effect, greatly reduce the generation of accident.
2, this stainless steel composite pipe for being suitable for high-temperature medium conveying, by the setting of stainless steel lining, by insulating layer
Keep apart with stainless steel layer, facilitate the filling of insulating layer, also can guarantee that the bellows segment of stainless steel layer can be due to pressure smoothly
Deformation.
3, design is scientific and reasonable for the utility model, loses, is easily achieved with reduction explosion probability, safe and reliable, reduction
The advantages of, it is a kind of stainless steel composite pipe with higher innovation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols
1- carbon steel layer, 2- insulating layer, 3- bellows segment, 4- stainless steel lining, 5- flat segments.
Specific embodiment
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of this utility model cannot be limited by this.
A kind of stainless steel composite pipe suitable for high-temperature medium conveying, including stainless steel layer, insulating layer 2 and carbon steel layer 1,
Stainless steel layer, insulating layer and the carbon steel layer is set gradually from the inside to the outside, and innovation is: the stainless steel layer by
Integrally formed flat segments 5 and bellows segment 3 are constituted, and flat segments and bellows segment are uniformly at intervals.
The outer surface of the bellows segment and the outer surface flush of flat segments.
Further include stainless steel lining 4, is provided with stainless steel lining between the stainless steel layer and insulating layer.
By the setting of bellows segment on stainless steel layer, the ability that can use its deformation effectively avoids making because being heated in pipeline
Pressure is excessive, thus the problem of expansion is burst.When the medium overheat conveyed in pipeline, stainless steel layer passes through bellows segment thereon
Deformation greatly reduces the generation of accident to have the function that increase space, pipe expansion is avoided to burst.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
