Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, specifically to a kraft pipe with a protective structure. Background Technology

[0002] As is well known, kraft pipes are widely used in chemical, petroleum, natural gas, water supply and drainage and other fields as important transportation pipelines. However, traditional kraft pipes face many challenges in practical applications.

[0003] Pipelines laid underground or on the seabed often need to withstand external pressure from soil, rocks or other heavy objects. This pressure may cause the pipeline to deform or rupture. Accidental impacts, excavation operations or other human activities during construction may cause physical damage to the pipeline, such as scratches and dents. Traditional pipelines are less adaptable to minor deformations caused by temperature changes or fluctuations in internal fluid pressure, and may experience poor sealing or structural damage after long-term operation.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a carat tube with a protective structure, which has the following beneficial effects:

[0017] This protective Krah pipe, through its inner liner, reinforcing plates, reinforcing rings, protective tube, and reinforcing tube, effectively disperses external pressure and prevents deformation or damage caused by excessive local stress. The reinforcing rings fit tightly with the reinforcing plates to prevent excessive bending, further enhancing the pipe's pressure resistance. The protective tube provides an extra layer of physical protection for the entire structure, resisting external mechanical damage such as impacts and scratches. The spirally wound reinforcing tube increases the overall structural pressure resistance. This multi-layered Krah pipe enhances the pipe's safety and durability.

[0018] This protective pipe, with its protective structure, features a protective mechanism consisting of a support cylinder, a support rod, and a spring. This mechanism absorbs and disperses impact energy when the pipe is subjected to external forces, reducing direct damage. The elastic properties of the spring allow the support rod to slide within the support cylinder, adapting to minor deformations caused by temperature changes or fluctuations in internal fluid pressure, thus maintaining the integrity of the pipe. The spring in the protective mechanism can also alleviate fatigue stress generated during long-term use, reducing the risk of rupture caused by aging and extending the service life of the pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4A corrugated tube with a protective structure includes an inner liner tube 1, reinforcing plates 2, reinforcing rings 3, a protective tube 4, a reinforcing tube 5, an anti-corrosion layer, and a protective mechanism. The outer wall of the inner liner tube 1 is annularly arranged with multiple sets of reinforcing plates 2. Multiple sets of reinforcing rings 3 are evenly fitted laterally onto the outer wall of the multiple sets of reinforcing plates 2. The protective tube 4 is installed on the outer wall of the multiple sets of reinforcing rings 3. The reinforcing tube 5 is spirally wound and fixed to the outer wall of the protective tube 4. The protective mechanism is installed between the inner liner tube 1 and the protective tube 4. The protective mechanism includes a support cylinder 6, a support rod 7, and a spring 8. The reinforcing rings 2 and the reinforcing tube 5 are connected in a spiral manner. A groove 9 is formed between the reinforcing rings 3, and the support cylinder 6 is installed in the groove 9. The support rod 7 is slidably installed on the top of the support cylinder 6. The spring 8 is sleeved on the outer wall of the support cylinder 6 and the support rod 7. The bottom end of the spring 8 is connected to the top wall of the inner liner tube 1, and the top end of the spring 8 is fixedly connected to the inner wall of the protective tube 4. The outer walls of the protective tube 4 and the reinforcing tube 5 are both provided with the anti-corrosion layer. In this embodiment, the reinforcing plates 2 are evenly distributed on the outer wall of the inner liner tube 1, which can effectively disperse the pressure from the outside and prevent the pipe from deforming or being damaged due to excessive local stress. The reinforcing rings 3 are horizontally sleeved on the reinforcing plates 2. This further enhances the stability of the overall structure, especially when subjected to high pressure and large-diameter pipe connections, significantly improving its compressive strength. The reinforcing ring 3 fits tightly with the reinforcing plate 2, effectively preventing excessive bending of the pipe, ensuring stability in use, and extending its service life. The protective pipe 4 provides an extra layer of physical protection for the entire structure, preventing external mechanical damage such as impacts and scratches. The spiral winding structure of the reinforcing pipe 5 increases compressive strength. The protective mechanism, composed of the support cylinder 6, support rod 7, and spring 8, can absorb and disperse impact energy when the pipe is subjected to external force, reducing damage to the pipe. The elasticity of the spring 8 ensures that the support rod 7... It can slide within the support cylinder 6, thus adapting to the slight deformation of the pipeline caused by temperature changes or changes in internal fluid pressure, maintaining the integrity of the pipeline. The spring 8 in the protective mechanism can also alleviate the fatigue stress generated by the pipeline due to long-term use, reduce the possibility of pipeline cracking due to aging, thereby extending the service life of the pipeline and maintaining good sealing performance. The outer walls of the protective tube 4 and the reinforcing tube 5 are coated with an anti-corrosion layer, which plays a role in preventing corrosion of the outer wall of the Krah pipe, further extending the service life of the Krah pipe. The robust structure and stable performance ensure smooth flow of fluid in the pipeline and reduce the decrease in conveying efficiency caused by pipeline deformation.

[0026] Preferably, in this embodiment, a tapered tube 10 is installed at one end of the reinforcing tube 5. A brass wire 11 is pre-embedded in the inner wall of the tapered tube 10. The design of the tapered tube 10 makes it easier to align during installation, reduces errors in the installation process, and improves installation efficiency. The operator only needs to insert the pipe to be connected into the tapered tube 10 to ensure the correct alignment position, and then perform electrofusion connection. During the electrofusion connection process, the brass wire 11 can promote the full fusion of the thermoplastic material on the inner wall of the tapered tube 10 to form a seamless connection interface, effectively preventing medium leakage and ensuring sealing. The brass wire 11 can form a metallurgical bond with the molten plastic material, enhancing the mechanical strength of the connection part. This bonding method is more robust than a simple physical connection and can withstand higher pressure and tension.

[0027] Preferably, in this embodiment, the reinforcing plate 2 is arc-shaped. The arc-shaped design allows the reinforcing plate 2 to be more evenly distributed on the outer wall of the inner liner pipe 1, avoiding local stress concentration. This helps to evenly distribute external pressure and internal medium pressure throughout the pipeline system, reducing the risk of deformation or damage caused by excessive local stress. The arc-shaped reinforcing plate 2 provides a larger contact area, which can provide stronger support when subjected to high pressure. Compared with the planar reinforcing plate 2, the arc-shaped design can better resist bending and torsional forces, enhancing the overall structure's compressive strength and stability.

[0028] Preferably, in this embodiment, five sets of reinforcing ribs 12 are provided on the outer wall of the reinforcing pipe 5 along its length. The five sets of reinforcing ribs 12 are evenly distributed along the length of the reinforcing pipe 5, which can evenly distribute the external pressure and internal medium pressure to the entire pipeline system. This design enables the reinforcing pipe 5 to provide stronger support when subjected to high pressure, reducing the risk of deformation or damage caused by excessive local stress.

[0029] Preferably, in this embodiment, the inner liner 1 is made of PE material. PE material has excellent chemical stability and can resist the corrosion of most acids, alkalis and solvents. It is suitable for conveying various corrosive media, such as chemical raw materials and wastewater, and is particularly suitable for installation in complex environments such as underground pipelines, bridges and tunnels.

[0030] Preferably, in this embodiment, the protective pipe 4 is made of ABS material. ABS material has excellent impact resistance and can maintain structural integrity when subjected to external impact or vibration, reducing the risk of damage caused by impact. This is especially important for applications in complex environments such as underground pipelines, bridges and tunnels, ensuring the long-term reliability of the pipeline system.

[0031] Preferably, in this embodiment, the reinforcing pipe 5 is made of HDPE material. HDPE material has high tensile strength and compressive strength, and can maintain structural integrity when subjected to large tensile and compressive forces. HDPE material can maintain good physical properties over a wide temperature range, making it suitable for applications under different climatic conditions, such as water pipelines in cold regions and industrial pipelines in high-temperature environments.

[0032] Preferably, in this embodiment, the anti-corrosion layer is an epoxy anti-corrosion coating. Epoxy anti-corrosion coatings can resist the erosion of most acids, alkalis, salts, solvents and other corrosive media. They are suitable for pipeline systems in many fields such as petrochemicals, water treatment, mining and metallurgy. Epoxy coatings have excellent chemical stability and weather resistance, and can maintain good anti-corrosion performance for a long time, thus extending the service life of the pipeline system.
