Abstract
The invention relates to an anticorrosion straight pipe. The straight pipe is composed of an outer layer (1), an inner layer (2), a first flange (3) and a second flange (4); the inner layer (2) is arranged on the inner wall of the outer layer (1) and is provided with a first folding side (21) and a second folding side (22); the first folding side (21) and the second folding side (22) are arranged at the two ends of the inner layer (2) correspondingly and extend outwards in the vertical direction of the inner layer (2); the first flange (3) is arranged on the outer layer (1) and is tightly attached to the first folding side (21), a plate block (5) is further arranged on the second folding side (22), and the second flange is arranged on the outer layer (1) and is tightly attached to the plate block (5); and through the effect of an inner polytetrafluoroethylene protection layer, aging resistance, high temperature resistance and corrosion resistance of the straight pipe can be improved, most corrosion of concentrated nitric acid and chloroazotic acid can be resisted, and through an external steel pipe, the structural strength of the straight pipe is improved.
Description
Technical field
The present invention relates to a kind of straight tube, be specifically related to a kind of anticorrosion straight tube.
Background technology
Steel lining multiple tube, is using normal carbon steel pipe as matrix, the thermoplasticity of liner chemistry excellent in stability
Plastic tube, through cold drawn compound or rotation molding.The mechanical performance of its existing steel pipe, has again the corrosion resistant of plastic tube
Erosion, slow fouling, it is difficult to grow the feature of microorganism, is that transport acid, alkali, salt, the gas that is corrosive etc. are situated between
The ideal conduit of matter.It is widely used the medium in industries such as chemical industry, electric power, metallurgy, food to carry and ring
Protect processing system.Along with industrialized fast development, steel lining multiple tube is for height high pressure resistant, corrosion-resistant, resistance to
The aspects such as temperature have increasingly strict requirements.
Because above-mentioned defect, the design people, the most in addition research and innovation, to founding a kind of novel knot
The anticorrosion straight tube of structure so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide one can antiseptical straight tube.
Technical scheme is as follows:
A kind of anticorrosion straight tube, it is characterised in that: described straight tube is by outer layer (1), internal layer (2), the first flange
(3) and the second flange (4) constitute, described internal layer (2) is arranged on described outer layer (1) inwall, institute
State internal layer (2) and be provided with the first flanging (21) and the second flanging (22), described first flanging (21) and
Second flanging (22) is separately positioned on the two ends of described internal layer (2) and along described internal layer (2) vertical direction
Stretching out, described first flange (3) is arranged on described outer layer (1) and above and is close to described first flanging (21),
Being additionally provided with plate (5) on described second flanging (22), described second flange is arranged on described outer layer (1)
Go up and be close to described plate (5).
-described outer layer (1) is seamless steel pipe.
-described internal layer (2) is politef.
-described first flange (3) is slip-on welding flange, is fixed on described outer layer (1) by the way of welding.
-described second flange (4) position lap joint flange.
By such scheme, the present invention at least has the advantage that
The present invention, by the effect of interior politef protective layer, is greatly improved the height ageing-resistant, resistance to of straight tube
Warm, corrosion-resistant, the most corrosion including concentrated nitric acid and chloroazotic acid can be kept out, strengthened by outer steel pipe
The structural strength of straight tube.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technology of the present invention
Means, and can being practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate attached
After figure describes in detail such as.
Accompanying drawing explanation

Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1, a kind of anticorrosion straight tube described in a preferred embodiment of the present invention, described straight tube by outer layer 1,
Internal layer the 2, first flange 3 and the second flange 4 are constituted, and described internal layer 2 is arranged on described outer layer 1 inwall,
Described internal layer 2 is provided with the first flanging 21 and the second flanging 22, described first flanging 21 and the second flanging 22
It is separately positioned on the two ends of described internal layer 2 and stretches out along described internal layer 2 vertical direction, described first method
Blue 3 are arranged on described outer layer 1 and are close to described first flanging 21, and described second flanging 22 is additionally provided with
Plate 5, described second flange is arranged on described outer layer 1 and is close to described plate 5.
-described outer layer 1 is seamless steel pipe.
-described internal layer 2 is politef.
-described first flange 3 is slip-on welding flange, is fixed on described outer layer 1 by the way of welding.
-described 4 lap joint flanges of second flange.
The present invention, by the effect of interior politef protective layer, is greatly improved the height ageing-resistant, resistance to of straight tube
Warm, corrosion-resistant, the most corrosion including concentrated nitric acid and chloroazotic acid can be kept out, strengthened by outer steel pipe
The structural strength of straight tube.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also
Can make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
