Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, specifically a novel composite reinforced pipeline. Background Technology

[0002] In the current field of pipeline engineering, whether it is municipal water supply and drainage, oil and gas transportation, or chemical media transmission, the performance requirements for pipelines are becoming increasingly stringent. Traditional pipelines are mostly made of single metal materials or ordinary plastic materials, which have obvious performance shortcomings. Although metal pipelines have high strength, they are heavy, difficult to construct, and susceptible to corrosion. Especially when transporting media containing corrosive components, their service life is greatly shortened, and the later maintenance costs are high.

[0003] However, traditional pipes still have certain shortcomings in use: Existing composite fiber pipes have failed to fully leverage the synergistic advantages of glass fiber and basalt fiber in their material combinations. Some simply mix the two fibers without scientific proportioning design, resulting in unstable overall pipe performance. Others still use traditional straight-wall or flange connections in their structural design, leading to poor sealing and insufficient strength at the connection points. This can easily cause problems such as media leakage and connection breakage during long-term use, seriously affecting the safety and reliability of the pipeline system. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of composite reinforced pipeline to solve the problems mentioned in the background art, such as the lack of scientific proportioning design, which leads to unstable overall pipeline performance; or the use of traditional straight wall or flange connection in structural design, resulting in poor sealing and insufficient strength at the connection points, which can easily lead to media leakage and connection point breakage during long-term use, seriously affecting the safety and reliability of the pipeline system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel composite reinforced pipe includes a first pipe and a second pipe disposed on the side of the first pipe. The first and second pipes are positioned opposite each other. A first flange and a second flange are fixedly connected to the outer surfaces of the first and second pipes. Threaded holes are respectively provided on the sides of the first and second flanges. A connecting screw is disposed between the first and second flanges. The two ends of the connecting screw pass through two sets of threaded holes and are threadedly connected to the first and second flanges respectively. Mounting nuts are threadedly connected to the two ends of the connecting screw, and the two sets of mounting nuts are respectively located on the sides of the first and second flanges.

[0006] As a preferred embodiment of this utility model, a connecting pipe is fixedly connected to the end of the first pipe. The connecting pipe is located on the side of the first flange. An installation groove is formed on the outer surface of the connecting pipe, and a sealing ring is fixedly connected in the installation groove.

[0007] As a preferred embodiment of this utility model, an auxiliary sleeve is fixedly connected to the end of the second pipe. The auxiliary sleeve is located on the side of the second flange, the connecting pipe extends into the auxiliary sleeve, and the sealing ring abuts against the auxiliary sleeve.

[0008] As a preferred embodiment of this utility model, reinforcing ribs are fixedly connected between the first pipe and the first flange, and between the second pipe and the second flange, respectively, and both sets of reinforcing ribs are triangular in shape.

[0009] As a preferred embodiment of this utility model, both the first pipe and the second pipe are made of glass fiber and basalt fiber, and the first pipe and the second pipe are of the same length.

[0010] As a preferred embodiment of this utility model, the first flange and the second flange are the same size, and both the first flange and the second flange are made of brass.

[0011] As a preferred embodiment of this utility model, the auxiliary sleeve is tapered, and both the connecting pipe and the auxiliary sleeve are made of glass fiber and basalt fiber.

[0012] As a preferred embodiment of this utility model, three sealing rings are provided, and all three sealing rings are made of nitrile rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by using a first pipe, a second pipe, a first flange, a second flange, a connecting bolt, and a mounting nut in combination, the strength of the pipe connection can be improved. The first pipe and the second pipe are precisely connected through the first flange and the second flange at their ends. The connecting bolt passes through the bolt holes on the two flanges and is tightened with the mounting nut to form a stable and reliable connection structure. This not only effectively avoids the problem of medium leakage caused by loose bolts in traditional flange connection methods, but also significantly improves the tensile strength and shear resistance of the connection by optimizing the flange structure and bolt distribution, thereby ensuring the safety and reliability of the pipeline system during long-term operation.

[0014] 2. In this utility model, by setting up a first pipe, a second pipe, a connecting pipe, a sealing ring, an auxiliary sleeve, and reinforcing ribs in combination, the first and second pipes are made of glass fiber and basalt fiber as reinforcing materials, which improves the strength of the pipes and further enhances the sealing performance of the pipe connection. The connecting pipe is sleeved on the outer surface of the connecting pipe, and the sealing ring is placed between the connecting pipe and the auxiliary sleeve to prevent the medium from leaking from the connection. This provides additional protection and reinforcement for the entire connection. The reinforcing ribs are evenly distributed between the pipe and the flange, which greatly improves the bending and torsional resistance of the connection, so that the pipeline system can still maintain a stable connection state when facing complex working conditions and external stress.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] For examples, please refer to Figures 1-4 This utility model provides a technical solution: A novel composite reinforced pipe includes a first pipe 1, a second pipe 2 disposed on the side of the first pipe 1, the first pipe 1 and the second pipe 2 being positioned opposite each other, a first flange 3 and a second flange 4 being fixedly connected to the outer surfaces of the first pipe 1 and the second pipe 2, threaded holes 8 being disposed on the sides of the first flange 3 and the second flange 4 respectively, a connecting screw 5 being disposed between the first flange 3 and the second flange 4, the two ends of the connecting screw 5 passing through the two sets of threaded holes 8 respectively, the connecting screw 5 being threadedly connected to the first flange 3 and the second flange 4 respectively through the two sets of threaded holes 8, and mounting nuts 6 being threadedly connected to the two ends of the connecting screw 5 respectively, the two sets of mounting nuts 6 being located on the sides of the first flange 3 and the second flange 4 respectively.

[0019] The first pipe 1 and the second pipe 2 are securely connected by passing the connecting screw 5 through the screw hole 8 and tightening it with the mounting nut 6.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a connecting pipe 10 is fixedly connected to the end of the first pipe 1. The connecting pipe 10 is located on the side of the first flange 3. An installation groove 11 is opened on the outer surface of the connecting pipe 10. A sealing ring 12 is fixedly connected in the installation groove 11. An auxiliary sleeve 9 is fixedly connected to the end of the second pipe 2. The auxiliary sleeve 9 is located on the side of the second flange 4. The connecting pipe 10 extends into the auxiliary sleeve 9. The sealing ring 12 abuts against the auxiliary sleeve 9. Reinforcing ribs 7 are fixedly connected between the first pipe 1 and the first flange 3, and between the second pipe 2 and the second flange 4. Both sets of reinforcing ribs 7 are triangular in shape. The materials of the first pipe 1 and the second pipe 2 are glass fiber and basalt fiber. The lengths of the first pipe 1 and the second pipe 2 are the same. The sizes of the first flange 3 and the second flange 4 are the same. The materials of the first flange 3 and the second flange 4 are brass. The auxiliary sleeve 9 is conical in shape. The materials of the connecting pipe 10 and the auxiliary sleeve 9 are glass fiber and basalt fiber. Three sealing rings 12 are provided. The materials of the three sealing rings 12 are nitrile rubber.

[0021] The working process of this utility model is as follows: When using the novel composite reinforced pipe designed in this scheme, first check whether the first pipe 1 and the second pipe 2 are in normal use. If both the first pipe 1 and the second pipe 2 are in normal use, then align the first flange 3 and the second flange 4, extend the connecting pipe 10 into the auxiliary sleeve 9, pass the connecting screw 5 through the screw hole 8, and tighten it with the mounting nut 6 to ensure that the first pipe 1 and the second pipe 2 are firmly connected. During the connection process, the reinforcing rib 7 can enhance the strength of the pipe connection and prevent deformation or damage due to excessive pressure. At the same time, the setting of the sealing ring 12 can effectively prevent leakage at the pipe connection and ensure the normal operation of the pipe.

[0022] The materials and proportions of the first pipe 1 and the second pipe 2 are as follows: the pipe body uses glass fiber and basalt fiber as reinforcing materials and resin as the matrix material. The mass proportion of glass fiber is 55%-65%, the mass proportion of basalt fiber is 15%-25%, and the mass proportion of resin is 20%-30%. At the same time, 1%-3% of curing agent (such as amine curing agent) and 0.5%-1.5% of accelerator (such as imidazole accelerator) are added to improve the curing performance and mechanical properties of the material. This allows the high strength and high corrosion resistance of glass fiber to fully synergize with the high temperature resistance and high impact resistance of basalt fiber, ensuring the overall strength of the pipe and improving its adaptability in harsh environments.

[0023] Manufacturing process: The pipe body is manufactured using a winding process, and the specific steps are as follows: Glass fiber and basalt fiber are mixed according to the designed ratio and then opened using a fiber opening machine to ensure uniform fiber dispersion. The resin, curing agent, and accelerator are mixed in proportion and stirred evenly to prepare a resin solution. The viscosity of the solution is controlled between 2000-3000 mPa·s to ensure that the fibers can be fully impregnated. The treated mixed fibers are fully impregnated with resin solution in an impregnation tank, and then, under the control of a winding machine, they are evenly wound onto a cylindrical mold according to a preset winding angle (usually ±45° cross winding) and winding tension. After the winding is completed, the mold and the winding layer are placed in the curing oven and cured according to the preset curing regime. The curing temperature is divided into two stages: the first stage is 80-100℃, and the temperature is maintained for 2-3 hours to allow the adhesive to initially cure; the second stage is 120-140℃, and the temperature is maintained for 3-4 hours to ensure that the adhesive is completely cured. After curing, wait for the mold to cool to room temperature, then demold the pipe from the mold to obtain the composite fiber pipe blank. The pipe blank is then processed by cutting, grinding and other subsequent processing to ensure that the length, outer diameter and inner wall roughness of the pipe meet the design requirements. The outer diameter tolerance of the pipe is controlled within ±0.5mm and the inner wall roughness Ra≤3.2μm.
