Description

Technical Field

[0001] This utility model relates to the field of internal wall pre-repair pipeline technology, specifically to an internal wall pre-repair pipeline for oil transportation. Background Technology

[0002] An oil pipeline (also known as a pipeline or conduit) consists of oil pipes and their accessories, and is equipped with corresponding oil pump units according to the needs of the process flow. It is designed and installed into a complete pipeline system to complete the tasks of oil unloading and transportation.

[0003] Oil pipeline systems, which are pipeline systems used to transport oil and petroleum products, mainly consist of oil pipelines, oil stations and other auxiliary equipment. They are one of the main equipment in the oil storage and transportation industry, and the most important equipment for transporting crude oil and petroleum products. Compared with railway and highway oil transportation, which are also land transportation modes, pipeline oil transportation has the characteristics of large capacity, good sealing, low cost and high safety factor.

[0004] Oil pipelines are generally made of steel pipes, connected by welding and flanges to form long pipelines, and valves are used for opening and closing control and flow regulation. Oil pipelines mainly employ isothermal transport, heated transport, and sequential transport processes. Pipeline corrosion and corrosion prevention are crucial aspects of pipeline maintenance. Currently, oil pipelines have become one of the main means of transporting oil and continue to have considerable development potential in the future.

[0005] Currently, existing technologies for pre-repairing internal walls in oil transportation pipelines typically involve pre-repairing cracks in the pipeline. During use, when the pipeline ruptures or deforms, the internal structure is compressed, releasing substances intended to repair the cracks. However, oil transportation pipelines have high internal pressure and rapid oil flow, which carries away the released substances, preventing them from completely covering and repairing the cracks. This results in the problem that the repair material cannot fully cover the cracks. Furthermore, during use, oil pipelines are interconnected via flanges, which are fixed with bolts, making the fixing structure relatively simple. When the fixing structure is damaged, the flanges may loosen, leading to oil leakage, indicating a problem with the pipeline's poor fixing structure. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1 to 7 This utility model provides a technical solution: an internally pre-repaired pipeline for oil transportation, comprising a pipe body 2, a connecting flange 16 fixedly connected to one side of the pipe body 2, an external anti-corrosion pipe 1 provided on the outside of the pipe body 2, the external anti-corrosion pipe 1 in contact with the connecting flange 16, an internal anti-corrosion pipe 3 provided inside the pipe body 2, the pipe body 2 being composed of an internal connecting pipe 4, an external connecting pipe 10, and a support block 5, a fixing rib 6 fixedly connected inside the external connecting pipe 10, a reinforcing rib 21 fixedly connected to one side of the fixing rib 6, and an external connecting pipe 10 fixedly connected to one side of the reinforcing rib 21, the reinforcing rib 21 being linearly arrayed, the external connecting pipe 10 in contact with the external anti-corrosion pipe 1, the internal connecting pipe 4 in contact with the internal anti-corrosion pipe 3, a fixing bolt 17 threadedly connected to one side of the connecting flange 16, and a fixing bolt 17 fixed to one side of the internal connecting pipe 4. A support block 5 is connected, and an external connecting pipe 10 is fixedly connected to one end of the support block 5. A connecting groove 9 is provided between the internal connecting pipe 4 and the external connecting pipe 10. The connecting groove 9 is separated by the support block 5 and is distributed in a ring array. A fixing frame 8 is fixedly connected to one side of the connecting groove 9 and is in close contact with the connecting groove 9. A repair fluid pipe 7 is fixedly connected inside the fixing frame 8. The repair fluid pipe 7 is distributed in a rectangular array inside the fixing frame 8 and is a glass tube. The pipeline is protected by setting an external anti-corrosion pipe 1 and an internal anti-corrosion pipe 3. The pipeline is reinforced by setting a fixing rib 6 and a reinforcing rib 21. The pipeline is divided by setting an external connecting pipe 10, an internal connecting pipe 4, and a support block 5. The pipeline is repaired by setting a connecting groove 9, a fixing frame 8, and a repair fluid pipe 7.

[0031] During use, the outer anti-corrosion pipe 1 reduces external damage to the pipeline, while the inner anti-corrosion pipe 3 reduces damage during use. However, after prolonged use, excessive internal pressure in the pipeline can cause cracks, damaging the inner anti-corrosion pipe 3. The inner connecting pipe 4 provides protection to prevent oil leakage. When the inner connecting pipe 4 cracks, the internal pressure of the oil diffuses outward through the crack and enters the connecting groove 9, squeezing the fixing frame 8. This causes the outer glass tube of the repair fluid pipe 7 to break, dispersing the internal repair fluid and filling the connecting groove 9, thus repairing the crack and achieving the purpose of completely covering the crack with the repair material.
