Description
Technical Field
[0001] This utility model relates to the field of organic alloy pipe technology, and in particular to a high-strength and high-toughness organic alloy pipe. Background Technology
[0002] High-strength and high-toughness organic alloy pipes have a wide range of applications in the industrial field, especially in the petroleum, chemical, natural gas transportation, construction and automotive industries. Because these pipelines often face extreme environmental conditions such as high pressure, high temperature and strong corrosion, the performance requirements of the pipeline materials are extremely high.
[0003] While existing organic alloy pipes possess certain advantages, such as corrosion resistance, high-temperature resistance, and good mechanical properties, they still have limitations in terms of the balance between strength and toughness, and fatigue performance during long-term use. Furthermore, turbulence and uneven flow velocity occur when fluid flows within the pipe, leading to reduced fluid transfer efficiency. This is particularly problematic in applications requiring efficient heat or mass transfer, where uneven fluid flow reduces the overall system efficiency. Therefore, a high-strength, high-toughness organic alloy pipe is proposed to address these issues. Utility Model Content
[0004] In order to address the technical problems in the prior art, although organic alloy pipes have good performance in some aspects, they still have certain limitations in terms of the balance between strength and toughness, fatigue performance in long-term use, etc., and the turbulence and uneven flow velocity generated when the fluid flows in the pipe, which leads to a reduction in fluid transmission efficiency, this application provides a high-strength and high-toughness organic alloy pipe.
[0005] This utility model proposes a high-strength and high-toughness organic alloy pipe, which includes an organic alloy pipe body, comprising an inner lining layer, a reinforcing layer, a substrate layer, an insulating layer, and an anti-corrosion coating.
[0006] The outer surface of the organic alloy tube body is provided with a reinforcing mechanism, which includes an annular groove. The annular design of the annular groove helps to reduce the friction of the fluid.
[0007] Preferably, the inner lining layer is fixedly bonded to the inner wall of the reinforcing layer by an adhesive, and the material of the inner lining layer is aluminum alloy.
[0008] Through the above technical solution, the inner lining is fixedly bonded to the reinforcing layer with an adhesive. The main function of the inner lining is to isolate it from the fluid and prevent the organic alloy pipe body material from reacting or corroding with the transported medium. The corrosion resistance of aluminum alloy enables the inner lining to prevent corrosive fluids from damaging the organic alloy pipe body.
[0009] Preferably, the reinforcing layer is made of carbon fiber, and the matrix layer is disposed between the inner liner layer and the reinforcing layer.
[0010] Through the above technical solution, the reinforcing layer is made of carbon fiber material, which can provide additional strength and enhance the tensile and compressive strength of the organic alloy tube body. The matrix layer combines the strength of the reinforcing layer with the function of the inner lining layer, effectively and evenly distributing the internal and external stresses on the organic alloy tube body, so that the organic alloy tube body remains stable under high pressure.
[0011] Preferably, the substrate layer is made of carbon fiber composite material, and the insulating layer is disposed between the substrate layer and the anti-corrosion coating.
[0012] Through the above technical solution, the carbon fiber composite material of the matrix layer has very high tensile strength and rigidity, which allows the organic alloy tube body to withstand higher loads and pressures, and avoids deformation of the organic alloy tube body when subjected to external forces. The insulation layer is located between the matrix layer and the anti-corrosion coating, which can effectively isolate the current inside and outside the organic alloy tube body and prevent the organic alloy tube body from being affected by electro-corrosion.
[0013] Preferably, the insulating layer is made of polyethylene, and the anti-corrosion coating is made of acrylic acid.
[0014] Through the above technical solutions, the high resistivity of polyethylene gives the organic alloy pipe body excellent electrical insulation, preventing electrical accidents caused by current passing through the organic alloy pipe body. The anti-corrosion coating is the outer coating of the organic alloy pipe body. The acrylic coating can firmly adhere to the outer surface of the organic alloy pipe body, forming a strong protective layer to avoid external damage such as mechanical wear and scratches.
[0015] Preferably, the reinforcing mechanism further includes a threaded groove formed on the outer surface of the insulating layer, and a plurality of elongated grooves formed on the outer surface of the substrate layer.
[0016] Through the above technical solution, by opening threaded grooves on the outside of the insulation layer, the thickness of the threaded grooves is about one-third of the wall thickness of the insulation layer, which can maintain sufficient strength and durability, while avoiding adverse effects on the electrical performance of the insulation layer. The threaded grooves can be used for mechanical connection or fixation with other components, thereby enhancing the stability and fixation of the overall structure. By opening multiple elongated grooves on the outer surface of the base layer, the elongated grooves are located in the middle of the base layer and are about one-third of the wall thickness of the base layer. The presence of the elongated grooves allows the organic alloy tube body to better distribute the stress when subjected to internal and external pressure, thereby improving the stability of the structure.
[0017] Preferably, the outer surface of the reinforcing layer is provided with honeycomb-shaped grooves, and the annular groove is formed on the inner wall of the inner lining layer.
[0018] The above technical solution involves creating honeycomb-shaped grooves on the outer surface of the reinforcing layer. The thickness of these grooves is approximately one-third of the wall thickness of the reinforcing layer. These grooves help improve the strength of the reinforcing layer, making it less prone to cracking or deformation under external pressure. Additionally, annular grooves are created on the inner wall of the lining layer, with a thickness of approximately one-third of the lining layer's wall thickness. These annular grooves reduce the friction of the fluid within the organic alloy pipe body, thereby improving fluid transport efficiency and reducing energy loss.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. By setting up an inner lining, reinforcing layer, matrix layer, insulation layer, and anti-corrosion coating, the main function of the inner lining is to isolate it from the fluid. The corrosion resistance of aluminum alloy allows the inner lining to prevent corrosive fluids from damaging the organic alloy pipe body. The reinforcing layer uses carbon fiber material to provide additional strength. The matrix layer combines the strength of the reinforcing layer with the function of the inner lining, effectively and evenly distributing the internal and external stresses on the organic alloy pipe body. The carbon fiber composite material of the matrix layer has very high tensile strength and rigidity, which allows the organic alloy pipe body to withstand higher loads and pressures. The insulation layer is located between the matrix layer and the anti-corrosion coating, and can... It effectively isolates the internal and external currents of the organic alloy tube body. The high resistivity of polyethylene gives the organic alloy tube body excellent electrical insulation. The anti-corrosion coating is the outer coating of the organic alloy tube body. The acrylic coating can firmly adhere to the outer surface of the organic alloy tube body to form a strong protective layer, avoiding external damage such as mechanical wear and scratches. It solves the technical problem that although the organic alloy tube has good performance in some aspects, such as corrosion resistance, high temperature resistance and good mechanical properties, there are still certain limitations in the balance between strength and toughness and fatigue performance in long-term use.
[0021] 2. By incorporating a reinforcing mechanism, the friction of the fluid is reduced. Threaded grooves are formed on the outer surface of the insulation layer, with a thickness approximately one-third that of the insulation layer wall, ensuring sufficient strength and durability. These grooves can be used for mechanical connection or fixation with other components. Multiple elongated grooves are formed on the outer surface of the base layer, allowing for better stress distribution when the organic alloy tube body is subjected to internal and external pressures. Honeycomb grooves are formed on the outer surface of the reinforcing layer, contributing to increased strength. Annular grooves are formed on the inner wall of the liner layer, reducing friction within the organic alloy tube body and thus improving fluid transport efficiency. This solves the problem in existing technologies where turbulence and uneven flow velocity occur during fluid flow within pipes, leading to reduced fluid transfer efficiency. This is particularly relevant in applications requiring high-efficiency heat or mass transfer, where uneven fluid flow reduces the overall system efficiency. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figures 1-6 A high-strength and high-toughness organic alloy pipe includes an organic alloy pipe body 1, wherein the organic alloy pipe body 1 includes an inner lining layer 2, a reinforcing layer 21, a substrate layer 3, an insulating layer 4, and an anti-corrosion coating 5.
[0031] To prevent corrosive fluids from damaging the organic alloy pipe body 1, the inner lining layer 2 is fixedly bonded to the inner wall of the reinforcing layer 21 with an adhesive. The inner lining layer 2 is made of aluminum alloy. The main function of the inner lining layer 2 is to isolate it from the fluid and prevent the material of the organic alloy pipe body 1 from reacting or corroding with the transported medium. The corrosion resistance of aluminum alloy enables the inner lining layer 2 to prevent corrosive fluids from damaging the organic alloy pipe body 1.
[0032] To ensure the stability of the organic alloy tube body 1 under high pressure, the reinforcing layer 21 is made of carbon fiber, and the matrix layer 3 is disposed between the inner liner layer 2 and the reinforcing layer 21. The reinforcing layer 21, made of carbon fiber, provides additional strength and enhances the tensile and compressive strength of the organic alloy tube body 1. The matrix layer 3 combines the strength of the reinforcing layer 21 with the function of the inner liner layer 2, effectively and evenly distributing the internal and external stresses on the organic alloy tube body 1, thus ensuring the stability of the organic alloy tube body 1 under high pressure.
[0033] To prevent the organic alloy tube body 1 from being affected by electro-corrosion, the base layer 3 is made of carbon fiber composite material, and the insulation layer 4 is placed between the base layer 3 and the anti-corrosion coating 5. The carbon fiber composite material of the base layer 3 has very high tensile strength and rigidity, which allows the organic alloy tube body 1 to withstand higher loads and pressures, and prevents the organic alloy tube body 1 from deforming when subjected to external forces. The insulation layer 4 is located between the base layer 3 and the anti-corrosion coating 5, and can effectively isolate the current inside and outside the organic alloy tube body 1, preventing the organic alloy tube body 1 from being affected by electro-corrosion.
[0034] To form a robust protective layer and prevent external damage such as mechanical wear and scratches, the insulation layer 4 is made of polyethylene, and the anti-corrosion coating 5 is made of acrylic acid. The high resistivity of polyethylene gives the organic alloy tube body 1 excellent electrical insulation, preventing electrical accidents caused by current passing through the organic alloy tube body 1. The anti-corrosion coating 5 is the outer coating of the organic alloy tube body 1. The acrylic coating can firmly adhere to the outer surface of the organic alloy tube body 1, forming a robust protective layer to prevent external damage such as mechanical wear and scratches.
[0035] By setting up an inner liner 2, a reinforcing layer 21, a matrix layer 3, an insulating layer 4, and an anti-corrosion coating 5, the main function of the inner liner 2 is to isolate it from the fluid. The corrosion resistance of the aluminum alloy allows the inner liner 2 to prevent corrosive fluids from damaging the organic alloy pipe body 1. The reinforcing layer 21 is made of carbon fiber material, which provides additional strength. The matrix layer 3 combines the strength of the reinforcing layer 21 with the function of the inner liner 2, effectively and evenly distributing the internal and external stresses on the organic alloy pipe body 1. The carbon fiber composite material of the matrix layer 3 has very high tensile strength and rigidity, which allows the organic alloy pipe body 1 to withstand higher loads and pressures. The insulating layer 4 is located between the matrix layer 3 and the anti-corrosion coating 5. Between the coatings 5, the current inside and outside the organic alloy tube body 1 can be effectively isolated. The high resistivity of polyethylene gives the organic alloy tube body 1 excellent electrical insulation. The anti-corrosion coating 5 is the outer coating of the organic alloy tube body 1. The acrylic coating can firmly adhere to the outer surface of the organic alloy tube body 1, forming a strong protective layer to avoid external damage such as mechanical wear and scratches. This solves the technical problem that although organic alloy tubes have good performance in some aspects, such as corrosion resistance, high temperature resistance and good mechanical properties, they still have certain limitations in terms of the balance between strength and toughness and fatigue performance in long-term use.
[0036] To reduce the friction of the fluid, the outer surface of the organic alloy tube body 1 is provided with a reinforcing mechanism, which includes an annular groove 71. The annular design of the annular groove 71 helps to reduce the friction of the fluid.
[0037] To improve structural stability, the reinforcing mechanism also includes threaded grooves 6. Threaded grooves 6 are formed on the outer surface of the insulating layer 4, and multiple elongated grooves 61 are formed on the outer surface of the base layer 3. The threaded grooves 6 are formed on the outer surface of the insulating layer 4. The thickness of the threaded grooves 6 is about one-third of the wall thickness of the insulating layer 4, which can maintain sufficient strength and durability, while avoiding adverse effects on the electrical performance of the insulating layer 4. The threaded grooves 6 can be used for mechanical connection or fixation with other components, thereby enhancing the stability and fixation of the overall structure. Multiple elongated grooves 61 are formed on the outer surface of the base layer 3. The elongated grooves 61 are located in the middle of the base layer 3 and are about one-third the wall thickness of the base layer 3. The presence of the elongated grooves 61 allows the organic alloy tube body 1 to better distribute the stress when subjected to internal and external pressure, thereby improving the stability of the structure.
[0038] To improve fluid transport efficiency and reduce energy loss, a honeycomb-shaped groove 7 is formed on the outer surface of the reinforcing layer 21, and an annular groove 71 is formed on the inner wall of the inner liner layer 2. The honeycomb-shaped groove 7 on the outer surface of the reinforcing layer 21 has a thickness of about one-third of the wall thickness of the reinforcing layer 21. The honeycomb-shaped groove 7 helps to improve the strength of the reinforcing layer 21, making it less prone to cracking or deformation when subjected to external pressure. The annular groove 71 on the inner wall of the inner liner layer 2 has a thickness of about one-third of the wall thickness of the inner liner layer 2. The annular groove 71 can reduce the friction of the fluid in the organic alloy tube body 1, thereby improving fluid transport efficiency and reducing energy loss.
[0039] By setting up a reinforcing mechanism, the friction of the fluid is reduced. Threaded grooves 6 are formed on the outer surface of the insulation layer 4. The thickness of the threaded grooves 6 is about one-third of the wall thickness of the insulation layer 4, which can maintain sufficient strength and durability. The threaded grooves 6 can be used for mechanical connection or fixation with other components. Multiple elongated grooves 61 are formed on the outer surface of the base layer 3. The presence of the elongated grooves 61 allows the organic alloy tube body 1 to better distribute the force when subjected to internal and external pressure. Honeycomb grooves 7 are formed on the outer surface of the reinforcing layer 21. The honeycomb grooves 7 help to improve the strength of the reinforcing layer 21. Annular grooves 71 are formed on the inner wall of the inner lining layer 2. Annular grooves 71 can reduce the friction of the fluid in the organic alloy tube body 1, thereby improving the fluid transport efficiency. This solves the technical problem in the prior art where turbulence and uneven flow velocity occur when the fluid flows in the pipe, leading to a decrease in fluid transfer efficiency. Especially in some applications that require efficient heat or mass transfer, uneven fluid flow will reduce the efficiency of the overall system.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
