Abstract
The utility model provides a kind of stainless steel composite pipe road for making and connecting of stainless steel short tube, which solve existing stainless steel composite pipe conveyance conduits to connect misalignment, antiseptic property reduces, the technical issues of short life, it is equipped with steel pipe, the both ends of steel pipe are equipped with stainless steel short tube, and the utility model can be widely used for the conveying of fluid.
Description
Technical field
The utility model is related to a kind of conveyance conduits, and the stainless steel double connected is done with stainless steel short tube more particularly, to a kind of
Close pipeline.
Background technology
In the production and life of the mankind, through the conveyance conduit frequently with steel pipe as hot water.The advantages of steel pipe is anti-
Pressure energy power is strong, but its corrosion resistance is poor, then just takes anti-corrosion measure, thicker stainless steel plate composite plate in steel tube surface
Cost increase is very high, and then there are the following problems for relatively thin stainless steel plate composite plate：
Operation difficulty of (1) two stainless steel composite pipe when construction is welded to connect is very big.
(2) two stainless steel composite pipes are during being welded to connect, because pipeline easily occurs during production and transportation
It deforms and misalignment occurs and lead to stainless steel layer failure welding.
In this way, have led to using higher cost anti-corrosion composite steel tube interface and do not do any corrosion-resistant, cost compared with
The corrosion resistance of low clean steel pipe is essentially identical.
Invention content
The utility model provides one kind and avoiding welding misalignment, anti-corrosion aiming at technical problem present in background technology
Performance is good, long lifespan the stainless steel composite pipe road connected is made of stainless steel short tube.
For this purpose, the utility model is equipped with steel pipe, the both ends of steel pipe are equipped with stainless steel short tube, and the length of stainless steel short tube is 20
~200mm；The inner wall of steel pipe is equipped with interior stainless steel layer, and the inner surface of interior stainless steel layer is flushed with the inner surface of stainless steel short tube；
The outer wall of steel pipe is equipped with external anti-corrosion layer, and external anti-corrosion layer is 3PE or anti-corrosive organic coatings layer, and thickness is 0.5~5mm.Outer anti-corrosion
The periphery of layer is additionally provided with insulating layer.
Preferably, external anti-corrosion layer is stainless steel layer.
The utility model is simple in structure, applied widely.Stainless steel layer, outer stainless steel layer, 3PE or organic in composite steel tube
The setting of anticorrosive paint layer, effective solution steel pipe perishable technical problem.Stainless steel short tube is arranged in compound pipeline complex pipeline both ends,
Effective solution compound pipeline complex pipeline is during connecting welding caused by interface misalignment, anti-corrosive organic coatings layers welding heat damage
Anti-corrosion defect.The compound pipeline complex pipeline of several structure combination applications, formation just has corrosion-resistant, drag reduction, and the stream of weak link is not present
Body feed-line considerably increases the service life of pipeline.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Symbol description in figure：
1. steel pipe；2. stainless steel short tube；Stainless steel layer in 3.；4. external anti-corrosion layer.
Specific implementation mode
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
As shown in Figure 1, the inner wall of steel pipe 1 is equipped with interior stainless steel layer 3, interior stainless steel layer 3 is by stainless steel plate and carbon steel
It is formed after plate hot rolling is compound.The inner surface of interior stainless steel layer 3 is flushed with the inner surface of stainless steel short tube 2, reduces fluid
Flow resistance, it is more efficient.
The outer wall of steel pipe 1 is equipped with external anti-corrosion layer 4, and external anti-corrosion layer 4 can be stainless steel layer, 3PE or anti-corrosive organic coatings
Layer.When external anti-corrosion layer 4 is stainless steel layer, pass through the compound rear formation of stainless steel plate and carbon steel sheet hot rolling；When external anti-corrosion layer 4
For 3PE or anti-corrosive organic coatings layer when, use spraying or special inline process formed.The thickness of external anti-corrosion layer be 0.5~
5mm。
The both ends of steel pipe 1 are welded with stainless steel short tube 2, and the length of stainless steel short tube 2 is 20~200mm.When two pipes
When being connected between road, at the connection groove of two pipelines, welded with stainless steel welding stick (item).Pipeline whole in this way avoids
Anti-corrosion defect caused by pipe joint misalignment, the utility model are easy to operate, and antiseptic property is strong, the fluid delivery tube of long lifespan
Line, the structure are the optimal selections of anti-corrosion composite steel tube pipeline connection.
In addition, the periphery of external anti-corrosion layer 4 is also provided with thickness in the insulating layer of 40mm or more, the periphery of insulating layer may be used also
With equipped with the protective layer that thickness is 5~10mm, protective layer can be glass reinforced plastic pipe or polyethylene sheath, can also be by epoxy
Resin and fiber are entwined, as long as preferable protective action can be played.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent variations made by the utility model patent protection domain and change,
It all should still belong to the scope that the utility model claims book is covered.
Claims (2)
1. a kind of making the stainless steel composite pipe road connected of stainless steel short tube, it is equipped with steel pipe, it is characterized in that the two of the steel pipe
End is equipped with stainless steel short tube, and the length of the stainless steel short tube is 20~200mm；The inner wall of the steel pipe is equipped with interior stainless steel
Layer, the inner surface of interior stainless steel layer are flushed with the inner surface of stainless steel short tube；The outer wall of the steel pipe is equipped with external anti-corrosion layer；It is described
External anti-corrosion layer is 3PE or anti-corrosive organic coatings layer, and thickness is 0.5~5mm；The periphery of the external anti-corrosion layer is additionally provided with heat preservation
Layer.
2. according to claim 1 make the stainless steel composite pipe road connected of stainless steel short tube, it is characterised in that described outer
