Abstract
The utility model relates to a kind of for conveying the stainless steel composite pipe of hot steam, 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 tube wall of the stainless steel layer is hollow structure, the outer wall of stainless steel layer is straight structure, the inner wall of stainless steel layer is wavy shaped configuration, and the cavity between straight outer wall and waveform inner wall forms expansion buffer chamber.Design is scientific and reasonable for the utility model, have the advantages that reduce explosion probability, it is safe and reliable, reduce that loss, heat insulation effect is strong, is easily achieved, be 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 used for
Convey the stainless steel composite pipe of hot steam.
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 steam, certain dilatancy inevitably occurs for pipeline, it is long this with
It is past, there will be the security risk of explosion, not only cause any property loss, more likely injure life security.Therefore, one is invented
Kind be suitable for high-temperature steam conveying, reduce explosion probability, safe and reliable stainless steel composite pipe be very it is necessary to.
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 used to convey hot steam being easily achieved.
The utility model solves its technical problem and is achieved through the following technical solutions:
It is a kind of for conveying the stainless steel composite pipe of hot steam, including stainless steel layer, insulating layer and carbon steel layer, it is described not
Rust steel layer, insulating layer and carbon steel layer are set gradually from the inside to the outside, it is characterised in that: the tube wall of the stainless steel layer is hollow knot
Structure, the outer wall of stainless steel layer are straight structure, and the inner wall of stainless steel layer is wavy shaped configuration, straight outer wall and waveform inner wall
Between cavity formed expansion buffer chamber.
Moreover, intracavitary filled with heat-barrier material in the expansion buffer.
Moreover, the stainless steel layer inner wall and outer wall with a thickness of 5-20mm.
It the advantages of the utility model and has the beneficial effect that
1, this is for conveying stainless steel composite pipe of hot steam, can be with by the setting of expansion buffer chamber on stainless steel layer
It effectively avoids keeping pressure excessive because being heated in pipeline using its ability deformed, thus the problem of expansion is burst.When defeated in pipeline
When the medium overheat sent, stainless steel layer passes through the deformation of bellows segment thereon, to reach increase space, pipe expansion is avoided to burst
Effect, greatly reduces the generation of accident；In addition, hollow structure also functions to certain heat insulation effect.
2, this is for conveying stainless steel composite pipe of hot steam, in use, itself or landfill and underground, or be mounted on ground with
On, by the setting of the intracavitary heat-barrier material of expansion buffer, it on the one hand can be avoided and hurt sb.'s feelings or shadow because of compound pipe outer wall overheat
On the other hand the problem of ringing underground environment also can play the role of heat preservation to medium.
3, design is scientific and reasonable for the utility model, and having reduces explosion probability, safe and reliable, reduction loss, heat insulation effect
By force, the advantages of being easily achieved 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- outer wall, 4- expansion buffer chamber, 5- inner wall.
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.
It is a kind of for conveying the stainless steel composite pipe of hot steam, including stainless steel layer, insulating layer 2 and carbon steel layer 1, it is described
Stainless steel layer, insulating layer and carbon steel layer are set gradually from the inside to the outside, and innovation is: the tube wall of the stainless steel layer is
Hollow structure, the outer wall 3 of stainless steel layer are straight structure, and the inner wall 5 of stainless steel layer is wavy shaped configuration, straight outer wall and wave
Cavity between shape wave inner wall forms expansion buffer chamber 4.
It is intracavitary filled with heat-barrier material (not shown) in the expansion buffer.
The stainless steel layer inner wall and outer wall with a thickness of 5-20mm, facilitate the deformation of waveform inner wall.
By the setting of expansion buffer chamber on stainless steel layer, can use its deformation ability effectively avoid because in pipeline by
Heat keeps pressure excessive, thus the problem of expansion is burst.When the medium overheat conveyed in pipeline, stainless steel layer passes through ripple thereon
The deformation of section greatly reduces the generation of accident to have the function that increase space, pipe expansion is avoided to burst；In addition, hollow
Structure also function to certain heat insulation effect.
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.
