Description
Technical field
The utility model relates to welded tube technical field, specially a kind of special stainless steel welded tube.
Background technique
Welded still pipe abbreviation welded tube, common steel or steel band weld manufactured steel after unit and mold cans
Pipe.Welded still pipe simple production process, high production efficiency, description is more, and equipment investment is few, but common intensity is lower than seamless steel
Pipe.Since the 1930s, with the progress of rapid development and the welding and inspection technology of quality strip steel rolling production, weldering
It stitches quality to be continuously improved, the description of welded still pipe is increasing, and especially in heat exchange, who is standby in more and more fields
With pipe, decorative tube, low-pressure fluid pipe etc. instead of seamless steel pipe.
Currently, welded tube in the market has the various shapes specifications such as straight seam welded pipe, spiral welded pipe, S type welded tube, but one
A little special use occasions, such as bending part, need to come using bending welded tube connecting pipe, current bending welded tube can not be effective
Raising weldering liquid in pipe flow be therefore further improved.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of special stainless steel welded tube
Problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of special stainless steel welded tube, including pipe
Body, the tube body include that integrally formed first traversing section, the second traversing section, third traversing section, first longitudinal direction section and second are vertical
To section, first traversing section is vertical with first longitudinal direction section, and the third traversing section is vertical with second longitudinal direction section, and described first is vertical
To vertical second traversing section of section and second longitudinal direction section, bending inwards on first traversing section has upper arc section and lower circular arc
Section, outward bending has upper raised section and lower convexity section on the third traversing section, and third traversing section end is cone
Structure；The inboard wall of tube body is equipped with corrosion resistant layer, and wearing layer is arranged on outer wall.
Preferably, the wearing layer uses GTCrMoNiCu high chromium material, and the wearing layer is with a thickness of 1mm-2mm.
Preferably, the corrosion resistant layer uses polyethylene coating or epoxy coating.
Preferably, the distance between the upper arc section and lower arc section are the 2/3-3/4 of the first traversing section diameter.
Preferably, the distance between the upper raised section and lower convexity section are 1.1-1.2 times of the first traversing section diameter.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model is novel in design, can be improved welded tube fluid pressure, wherein inwardly curved on the first traversing section
Folding has upper arc section and lower arc section, can be improved the pressure of fluid at feed liquor using this structure；Bent outward on third traversing section
Folding has upper raised section and lower convexity section, and third traversing section end is conical structure, and using this structure, fluid is flowed out from outlet
When pressure can nature increase, improve out liquid efficiency.
(2) in the utility model, inboard wall of tube body is equipped with corrosion resistant layer, and wearing layer is arranged on outer wall, can be improved tube body
Wear-resisting, antiseptic property is suitble to use under rugged environment, long service life.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work

Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of special stainless steel welded tube, including tube body, it is described
Tube body includes integrally formed first traversing section 1, the second traversing section 2, third traversing section 3, first longitudinal direction section 4 and second longitudinal direction section
5, first traversing section 1 is vertical with first longitudinal direction section 4, and the third traversing section 3 is vertical with second longitudinal direction section 5, and described first
Longitudinal sections 4 and vertical second traversing section 2 of second longitudinal direction section 5, bending inwards on first traversing section 1 has upper 6 He of arc section
Lower arc section 7, the distance between upper arc section 6 and lower arc section 7 are the 2/3-3/4 of 1 diameter of the first traversing section, using this structure
It can be improved the pressure of fluid at feed liquor.Outward bending has upper raised section 8 and lower convexity section 9, and institute on the third traversing section 3
Stating 3 end of third traversing section is conical structure, and the distance between upper raised section 8 and lower convexity section 9 are 1 diameter of the first traversing section
1.1-1.2 times, using this structure, fluid from pressure when outlet outflow can nature increase, improve out liquid efficiency；The tube body
Inner wall is equipped with corrosion resistant layer, and wearing layer is arranged on outer wall.
In the utility model, wearing layer uses GTCrMoNiCu high chromium material, and the wearing layer is with a thickness of 1mm-2mm.It is resistance to
