Abstract
The utility model discloses a kind of performance seamless reduced pipe, include a large-diameter pipe body and a path body, it is connected between large-diameter pipe body and path body by a transition conduit, the central shaft of large-diameter pipe body and path body coincides, large-diameter pipe body, path body and the wall thickness of transition conduit are 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 present utility model is that the mutual welding of multilayer pipe body phase is formed, in the case where body entirety is drastically heated or is drastically cooled, 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 crackle occurs for body is reduced, safety coefficient is improved.
Description
Technical field
The utility model is related to a kind of reduced pipe, more precisely, being a kind of performance seamless reduced pipe.
Background technology
Reduced pipe is also known as concentric reducer, is one of chemical industry pipe fitting, the connection for two kinds 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 in production and living than wide, different under the more violent environment of some cold and hot changes
Influence that what footpath pipe was subject to expand with heat and contract with cold is than larger, and the internal stress of body is larger, and crackle easily occurs for tube wall in the course of time, even
Security incident can be caused.
Utility model content
The utility model is mainly the technical problem solved present in prior art, thus provide it is a kind of absorb internal stress compared with
Strong performance seamless reduced pipe.
Above-mentioned technical problem of the present utility model 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, between large-diameter pipe body and path body
It is connected by a transition conduit, the central shaft of large-diameter pipe body and path body coincides, large-diameter pipe body, path body and transition conduit
Wall thickness it is 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 positioned at inner side
Cast-steel pipe and carbon steel pipe positioned at outside constitute, cast-steel pipe and the mutual welding of carbon steel pipe, in the also welding one of the inner side of cast-steel pipe
Titanium tube, in the outside of the carbon steel pipe also stainless steel tube of welding one.
As the utility model preferred embodiment, described large-diameter pipe body and the internal diameter ratio of path body are 7：5.
As the utility model preferred embodiment, described cast-steel pipe and the thickness ratio of carbon steel pipe are 5：3.
The tubing of performance seamless reduced pipe of the present utility model is that the mutual welding of multilayer pipe body phase is formed, overall anxious in body
Internal stress can be split by layer structure in the case that play is heated or is drastically cooled, the stress that so every layer body is subject to
Just greatly reduce, so as to reduce the internal stress of tubing, reduce the risk that crackle occurs for body, improve safety coefficient.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram of performance seamless reduced pipe of the present utility model；
Fig. 2 is the layer structure schematic diagram of the performance seamless reduced pipe tubing.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
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 between footpath body 10 and path body 20 by a transition conduit 30, large-diameter pipe body 10 is mutually overlapping 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.
Further improved as to the utility model, described large-diameter pipe body 10 and the internal diameter ratio of path body 20 are
7：5.
Further improved as to the utility model, 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 utility model is that the mutual welding of multilayer pipe body phase is formed, overall anxious in body
Internal stress can be split by layer structure in the case that play is heated or is drastically cooled, the stress that so every layer body is subject to
Just greatly reduce, so as to reduce the internal stress of tubing, reduce the risk that crackle occurs for body, improve safety coefficient.
Only illustrate mentality of designing of the present utility model in one embodiment above, in the case where system allows,
The utility model can expand to external more functional modules simultaneously, so as to extend its function to greatest extent.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
