Description

A thin-walled stainless steel tube with a cladding layer Technical Field

[0001] This utility model relates to the technical field of stainless steel pipes, specifically a thin-walled stainless steel pipe with a cladding layer. Background Technology

[0002] Stainless steel refers to steel that is resistant to corrosion from weak corrosive media such as air, steam, and water, as well as chemical corrosive media such as acids, alkalis, and salts. It is also known as stainless acid-resistant steel. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. The basic alloying elements of stainless steel also include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various applications for the structure and properties of stainless steel. Stainless steel also has very high strength, so it is widely used in some building components and conveying pipes.

[0003] For example, the thin-walled stainless steel pipe with a cladding layer, authorized by publication number "CN221743514U", solves the problem that existing thin-walled stainless steel pipes with cladding layers have relatively poor strength and are prone to deformation when subjected to impacts. The above-mentioned pipe has a sliding support frame between the inner and outer pipes, which can improve the overall strength of the pipe and facilitate the assembly of components. By setting an anti-corrosion layer, the corrosion resistance of the pipe can be effectively improved. By setting a wear-resistant layer, the wear resistance of the pipe can be improved. However, considering that the existing thin-walled stainless steel pipes with cladding layers have a fixed support frame placed in the cavity between the inner and outer pipes, which only serves a supporting function, the function is relatively simple and cannot meet more diversified use needs. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem that existing thin-walled stainless steel pipes with cladding have relatively limited functions and cannot meet more diversified usage needs, and to propose a thin-walled stainless steel pipe with cladding.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thin-walled stainless steel pipe with a coating layer, comprising an outer pipe and a wear-resistant layer, wherein the surface of the outer pipe is processed with a wear-resistant layer, the inner wall of the outer pipe is fixedly connected to a heat insulation layer, the inner wall of the heat insulation layer is bonded to a first adhesive layer, and a support mechanism is connected to the outer wall of the first adhesive layer.

[0006] Preferably, the support mechanism includes a first arc-shaped strip, the outer wall of which is bonded to a first adhesive layer, the lower end of which is fixedly connected to a support strip, and the lower end of which is fixedly connected to a second arc-shaped strip.

[0007] Preferably, the outer wall of the second arc-shaped strip is fixedly connected to the second adhesive layer, and the outer wall of the second adhesive layer is connected to a noise reduction structure.

[0008] Preferably, the noise reduction structure includes an inner tube, the outer wall of which is fixedly connected to a second adhesive layer, the outer wall of which is fixedly connected to a filler, and the inner wall of which is fixedly connected to an anti-corrosion layer.

[0009] Preferably, the inner wall of the support strip is fixedly connected to the filler, and the outer wall of the filler is fixedly connected to the first arc-shaped strip and the second arc-shaped strip.

[0010] The present invention proposes a thin-walled stainless steel pipe with a cladding layer, which has the following advantages: the heat insulation layer set between the outer and inner pipes can effectively reduce the heat transfer of the pipe body, making the stainless steel pipe suitable for scenarios with temperature requirements. The first arc-shaped strip, the support strip and the second arc-shaped strip in the support mechanism work together to not only enhance the structural strength of the pipe body, but also connect with the filler to further stabilize the overall structure. The filler in the noise reduction structure and the inner pipe are processed into an elliptical shape to reduce turbulence resistance, which can absorb and weaken the noise generated by the flow of fluid in the pipe or the external environment, improve the user experience, extend the service life of the stainless steel pipe and meet the needs of more usage scenarios.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Please refer to Figures 1-6: In this embodiment, a thin-walled stainless steel pipe with a coating layer includes an outer pipe 1 and a wear-resistant layer 2. The surface of the outer pipe 1 is processed with the wear-resistant layer 2. The inner wall of the outer pipe 1 is fixedly connected to the heat insulation layer 3. The inner wall of the heat insulation layer 3 is bonded to the first adhesive layer 4. The outer wall of the first adhesive layer 4 is connected to a support mechanism 5.

[0020] The support mechanism 5 includes a first arc-shaped strip 501, the outer wall of which is bonded to the first adhesive layer 4, the lower end of which is fixedly connected to the support strip 502, and the lower end of the support strip 502 is fixedly connected to the second arc-shaped strip 503.

[0021] The outer wall of the second arc-shaped strip 503 is fixedly connected to the second adhesive layer 6. The outer wall of the second adhesive layer 6 is connected to a noise reduction structure 7, which includes an inner tube 701. The outer wall of the inner tube 701 is fixedly connected to the second adhesive layer 6 to improve fluid transport efficiency. The inner tube 701 adopts an elliptical shape to reduce turbulence resistance and is suitable for drainage or gas transport systems. The outer wall of the inner tube 701 is fixedly connected to the filler 702. The inner wall of the inner tube 701 is fixedly connected to the anti-corrosion layer 703. Antibacterial materials such as silver ions and copper ions are added to the anti-corrosion layer 703 to inhibit the growth of microorganisms and is suitable for drinking water or medical fluids. The inner wall of the transport support strip 502 is fixedly connected to the filler 702. The filler 702 uses porous sound-absorbing materials (such as foam metal) and a damping coating to reduce fluid flow noise and meet the requirements of quiet scenarios. The outer wall of the filler 702 is fixedly connected to the first arc-shaped strip 501 and the second arc-shaped strip 503.

[0022] The heat insulation layer 3 set between the outer tube 1 and the inner tube 701 can effectively reduce the heat transfer of the tube body, making the stainless steel tube suitable for scenarios with temperature requirements. The first arc-shaped strip 501, the support strip 502 and the second arc-shaped strip 503 in the support mechanism 5 work together to not only enhance the structural strength of the tube body, but also connect with the filler 702 to further stabilize the overall structure. The filler 702 in the noise reduction structure 7 and the inner tube 701 are processed into an elliptical shape to reduce turbulence resistance. They can absorb and weaken the noise generated by the fluid flow in the tube or the external environment, improve the user experience, extend the service life of the stainless steel tube and meet the needs of more scenarios.

[0023] Working principle:

[0024] The outer tube 1, made of stainless steel, is sandblasted to form a wear-resistant layer 3 on its outer wall, which enhances its wear resistance and extends its service life. Meanwhile, the heat insulation layer 3 is made of ceramic fiber material, which effectively blocks external heat transfer and reduces energy loss. The first adhesive layer 4 uses high-temperature resistant and high-strength epoxy structural adhesive to ensure a tight connection between the support mechanism 5 and the heat insulation layer 3. The first arc strip 501, the support strip 502 and the second arc strip 503 are all made of high-strength aluminum alloy, which ensures the support strength and reduces the overall weight. The second adhesive layer 6 uses elastic sealant.

[0025] The second arc-shaped strip 503 is connected to the inner tube 701 by a second adhesive layer 6. The inner tube 701 is machined into an elliptical shape to reduce turbulence resistance. The inner tube 701 is made of stainless steel with a chrome-plated surface to improve its corrosion resistance. The smooth surface of the chrome-plated layer can further reduce fluid transport resistance. The filler 702 uses porous sound-absorbing materials (such as foam metal) combined with a damping coating to reduce fluid flow noise, meeting the requirements of quiet environments such as chiller rooms and laboratories. The anti-corrosion layer 703 also contains antibacterial materials such as silver ions and copper ions to inhibit microbial growth, making it suitable for drinking water or medical fluids. In this way, the various structures work together to significantly improve the performance of this thin-walled stainless steel pipe with a coating in terms of wear resistance, heat insulation, support, noise reduction, and corrosion resistance, meeting the needs of different applications. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
