[0002] Composite pipe is a type of pipe made of two or more different materials through a specific process. It is formed by bonding the layers of different materials together using physical or chemical methods to create a multi-layered structure.

[0003] In the existing technology, when using composite pipes for oil transportation, the pipeline is usually laid according to the most convenient and suitable route, which may result in some pipelines being laid in the external environment. Although most composite pipes are made of carbon steel on the outside and stainless steel on the inside, if no protective measures are taken for the pipeline, the pipeline is directly exposed to the external environment. The wind and sun in the natural environment will inevitably have a certain impact on the pipeline, which may lead to pipeline aging and damage, reducing the normal service life of the pipeline. Utility Model Content

[0005] To achieve the above objectives, a high-strength composite pipe that facilitates oil flow transportation is provided. The composite pipe has a multi-layered composite structure, with carbon steel and stainless steel layers arranged sequentially from the outside in. Two flanges are fixedly connected to the outer surface of the composite pipe, and two limiting rings are also fixedly connected to the outer surface. Each of the two limiting rings has two limiting blocks. Positioning blocks are movably connected to the inner surfaces of all four limiting blocks. A single protective shell is fixedly connected to two corresponding positioning blocks. Multiple slots are movably connected to the inner surfaces of both protective shells. Sealing buffer blocks are fixedly connected to the side surfaces of the slots. Multiple mating blocks are fixedly connected to the outer surfaces of both protective shells.

[0008] According to the high-strength composite pipe that facilitates oil flow transportation, the outer surface of the sealing buffer block is in contact with the protective shell, and the inner surface of the sealing buffer block is in contact with the composite pipe.

[0009] According to the high-strength composite pipe that facilitates oil flow and transportation, a limiting groove is provided on the connecting block, and the outer surface of the bolt is movably connected to the limiting groove.

[0010] According to the high-strength composite pipe that facilitates oil flow and transportation, the carbon steel layer covers the stainless steel layer.

[0011] According to the high-strength composite pipe that facilitates oil flow and transportation, the outer surface of the limiting ring is in contact with the protective shell and the sealing buffer block, respectively.

[0012] According to the high-strength composite pipe that facilitates oil flow and transportation, the bolt penetrates the mating block.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. By setting up protective shells and sealing buffer blocks, the composite pipe can be protected, thus preventing it from being directly exposed to the external environment during actual use, thereby extending the service life of the composite pipe in the external environment.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5 This utility model discloses a high-strength composite pipe for easy oil flow transportation, comprising a composite pipe 1. The composite pipe 1 has a multi-layer composite structure, with a carbon steel layer 2 and a stainless steel layer 3 arranged sequentially from the outside to the inside. Two flanges 4 are fixedly connected to the outer surface of the composite pipe 1, and two limiting rings 5 ​​are fixedly connected to the outer surface of the composite pipe 1. Each of the two limiting rings 5 ​​has two limiting blocks 6. Positioning blocks 7 are movably connected to the inner surfaces of the four limiting blocks 6. The same protective shell 8 is fixedly connected to the corresponding two positioning blocks 7. Multiple slots 9 are movably connected to the inner surfaces of the two protective shells 8. Sealing buffer blocks 10 are fixedly connected to the side surfaces of the slots 9. The outer surfaces of the two protective shells 8 are fixedly connected to... There are multiple docking blocks 11, and the same bolt 12 is movably connected to two corresponding docking blocks 11. The outer surface of the bolt 12 is threaded with a nut 13. The sealing buffer block 10 is made of nitrile rubber. A connecting groove 15 is opened on the protective shell 8. The outer surface of the slot 9 is movably connected to the connecting groove 15. The outer surface of the sealing buffer block 10 is in contact with the protective shell 8. The inner surface of the sealing buffer block 10 is in contact with the composite pipe 1. A limiting groove 14 is opened on the docking block 11. The outer surface of the bolt 12 is movably connected to the limiting groove 14. The carbon steel layer 2 covers the stainless steel layer 3. The outer surface of the limiting ring 5 is in contact with the protective shell 8 and the sealing buffer block 10 respectively. The bolt 12 passes through the docking block 11.

[0027] It should be noted that the setting of limit block 6 and positioning block 7 not only facilitates the initial connection between protective shell 8 and composite pipe 1, but also prevents the protective shell 8 from rotating after connection. Furthermore, the setting of flange 4 facilitates the docking of multiple composite pipes 1. The composite pipe 1 is made of carbon steel and stainless steel. Carbon steel has good strength, which can improve the overall strength of composite pipe 1 and ensure its normal service life. Stainless steel has good corrosion resistance, which makes composite pipe 1 less prone to softening or cracking due to long-term contact with oil, keeping the inner wall of the pipe smooth, reducing the transport resistance, and facilitating the transport of oil.

[0028] Working Principle: The two protective shells 8 protect the composite pipe 1, preventing it from being directly exposed to the external environment during use. Furthermore, the sealing buffer block 10 effectively seals the connection between the two protective shells 8, preventing moisture from the external environment from contacting the composite pipe 1 through the gap between the two protective shells 8, thus avoiding corrosion and other damage. This is because the sealing buffer block 10 is made of nitrile rubber, which has excellent sealing and cushioning properties, thus improving the sealing at the connection between the two protective shells 8 and preventing moisture from seeping into the composite pipe 1 during rain. Its cushioning effect also reduces the shock transmitted to the composite pipe 1 when the protective shells 8 are impacted by the external environment, lowering the probability of damage to the composite pipe 1 due to external impact. Finally, by rotating the nut 13 and unscrewing it from the bolt 12, the two protective shells can be released. The two protective shells 8 are fixed together, so that they can be removed from the composite tube 1. After the two protective shells 8 are removed, the restriction on the slot 9 and the sealing buffer block 10 can also be released, and the slot 9 and the sealing buffer block 10 can be removed from the protective shell 8 for replacement. When connecting the slot 9, the sealing buffer block 10 and the protective shell 8, the slot 9 is placed into the connecting groove 15. When connecting the protective shell 8 and the composite tube 1, the two positioning blocks 7 on the protective shell 8 are placed into the two limiting blocks 6 on the same side. Then, the above operation is repeated on the other side to make the two protective shells 8 fit together and make the sealing buffer blocks 10 on the two protective shells 8 contact each other. At the same time, the two sealing buffer blocks 10 can also contact the composite tube 1. Then, the bolt 12 is passed through the limiting groove 14 on the corresponding two mating blocks 11, and the nut 13 is screwed back onto the bolt 12 and tightened, so that the connection and fixation between the two protective shells 8 and the composite tube 1 can be achieved.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
