The invention discloses a kind of performance seamless reduced pipe, comprising a large-diameter pipe body and a path body, it is connected by a transition conduit between large-diameter pipe body and path body, the central shaft of large-diameter pipe body and path body coincides, large-diameter pipe body, the wall thickness of path body and transition conduit is equal, large-diameter pipe body, path body and transition conduit are made up of tubing, tubing is sandwich construction, main body is made up of the cast-steel pipe positioned at inner side and the carbon steel pipe positioned at outside, cast-steel pipe and the mutual welding of carbon steel pipe, in the inner side of the cast-steel pipe also titanium tube of welding one, in the outside of the carbon steel pipe also stainless steel tube of welding one.The tubing of performance seamless reduced pipe of the invention is formed for the mutual welding of multilayer pipe body phase, in the case where body is integrally drastically heated or drastically catches a cold, internal stress can be split by layer structure, the stress that so every layer body is subject to just is greatly reduced, so as to reduce the internal stress of tubing, the risk that body occurs crackle is reduced, safety coefficient is improve.
Description
Technical field
The present invention relates to a kind of reduced pipe, more precisely, being a kind of performance seamless reduced pipe.
Background technology
Reduced pipe, also known as concentric reducer, is one of chemical industry pipe fitting, for two kinds of connections of different tube diameters.It is divided into concentric size again
Head and eccentric reducer.Reduced pipe material includes stainless steel reduced pipe, steel alloy, reduced pipe carbon steel concentric reducer, reduced pipe 20
Steel q234q345 etc..Reduced pipe is applied than wide in production and living, different under the more violent environment of some cold and hot changes
Than larger, the internal stress of body is larger, and tube wall is susceptible to crackle in the course of time for influence that what footpath pipe was subject to expand with heat and contract with cold, or even
Security incident can be caused.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so that it is stronger to provide a kind of absorption internal stress
Performance seamless reduced pipe.
Above-mentioned technical problem of the invention is mainly what is be addressed by following technical proposals：
A kind of performance seamless reduced pipe, comprising a large-diameter pipe body and a path body, passes through between large-diameter pipe body and path body
One transition conduit is connected, and the central shaft of large-diameter pipe body and path body coincides, the wall of large-diameter pipe body, path body and transition conduit
Thick equal, large-diameter pipe body, path body and transition conduit are made up of tubing, and tubing is sandwich construction, and main body is by the casting positioned at inner side
Steel pipe and the carbon steel pipe composition positioned at outside, cast-steel pipe and the mutual welding of carbon steel pipe, in the inner side of the cast-steel pipe also titanium tube of welding one,
In the outside of the carbon steel pipe also stainless steel tube of welding one.
Used as preferred embodiments of the present invention, described large-diameter pipe body and the internal diameter ratio of path body are 7：5.
Used as preferred embodiments of the present invention, described cast-steel pipe and the thickness ratio of carbon steel pipe are 5：3.
The tubing of performance seamless reduced pipe of the invention is formed for the mutual welding of multilayer pipe body phase, is integrally drastically received in body
Heat or internal stress can be split by layer structure in the case of drastically catching a cold, the stress that so every layer body is subject to is just greatly
To reduce, so as to reduce the internal stress of tubing, the risk that body occurs crackle is reduced, improve safety coefficient.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram of performance seamless reduced pipe of the invention；
Fig. 2 is the layer structure schematic diagram of the performance seamless reduced pipe tubing.
Specific embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in Figure 1 and Figure 2, a kind of performance seamless reduced pipe 1, comprising a large-diameter pipe body 10 and a path body 20, greatly
It is connected by a transition conduit 30 between footpath body 10 and path body 20, large-diameter pipe body 10 is mutually overlapped with the central shaft of path body 20
Close, large-diameter pipe body 10, path body 20 are equal with the wall thickness of transition conduit 30, large-diameter pipe body 10, path body 20 and transition conduit 30
It is made up of tubing 40, tubing 40 is sandwich construction, and main body is by the cast-steel pipe 41 positioned at inner side and the structure of carbon steel pipe 42 positioned at outside
Into, cast-steel pipe 41 and the mutual welding of carbon steel pipe 42, in the inner side of the cast-steel pipe 41 also titanium tube 43 of welding one, in the outside of carbon steel pipe 42
The also stainless steel tube 44 of welding one.
Used as to further improvement of the present invention, described large-diameter pipe body 10 and the internal diameter ratio of path body 20 are 7：5.
Used as to further improvement of the present invention, described cast-steel pipe 41 and the thickness ratio of carbon steel pipe 42 are 5：3.
The tubing of the performance seamless reduced pipe of the invention is formed for the mutual welding of multilayer pipe body phase, is integrally drastically received in body
Heat or internal stress can be split by layer structure in the case of drastically catching a cold, the stress that so every layer body is subject to is just greatly
To reduce, so as to reduce the internal stress of tubing, the risk that body occurs crackle is reduced, improve safety coefficient.
Below mentality of designing of the invention is only illustrated in one embodiment, and in the case where system is allowed, the present invention can
To expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
The change or replacement expected without creative work, should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
