Description

Technical Field

[0001] This utility model belongs to the field of seamless steel pipe technology, and in particular relates to a high corrosion resistance and turbulence resistance seamless steel pipe for conveying refining fluids. Background Technology

[0002] Seamless steel pipes have advantages such as high structural strength and light weight, and are currently widely used as pipelines for transporting fluids. When using seamless steel pipes to transport liquid fluids such as oil and water over long distances, the fluid is prone to severe turbulence within the pipe. The occurrence of turbulence leads to uneven and significantly reduced fluid velocity, resulting in increased energy consumption and decreased transport efficiency. Existing steel pipes avoid turbulence by controlling the fluid velocity, which limits the fluid velocity and hinders efficient and rapid fluid transport. In addition, if the steel pipe is corroded externally, coupled with the turbulent flow of the fluid inside, the steel pipe will be very susceptible to damage.

[0003] Therefore, it is essential to invent a highly corrosion-resistant and turbulent-resistant seamless steel pipe for transporting refining fluids. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high corrosion-resistant and turbulent flow-resistant seamless steel pipe for conveying refining fluids, including an anti-turbulent flow steel pipe and a high-strength corrosion-resistant outer cylinder. The high-strength corrosion-resistant outer cylinder is fixedly installed on the outside of the anti-turbulent flow steel pipe. Flanges are fixedly installed at both ends of the anti-turbulent flow steel pipe and the high-strength corrosion-resistant outer cylinder. The high-strength corrosion-resistant outer cylinder is used to protect the anti-turbulent flow steel pipe inside itself. The anti-turbulent flow steel pipe is used to convey fluids.

[0005] The anti-turbulence steel pipe includes a bright steel pipe, a horizontal streamline body, and a vertical streamline body. Several horizontal and vertical streamline bodies are fixedly installed inside the bright steel pipe, with a gap between them. The horizontal streamline bodies are horizontally fixed inside the bright steel pipe, while the vertical streamline bodies are vertically fixed inside the bright steel pipe. The high-strength corrosion-resistant outer cylinder includes a reinforcing outer plate, a spiral skeleton, a corrosion-resistant outer cylinder, and a hollow cavity. Four reinforcing outer plates are fixedly installed on the bright steel pipe, and a spiral skeleton is fixedly installed on each of the four reinforcing outer plates. The corrosion-resistant outer cylinder is fixedly installed on the outside of the four reinforcing outer plates. The gap between the bright steel pipe and the corrosion-resistant outer cylinder is the hollow cavity.

[0006] Preferably, the bright steel pipe has a corrosion-resistant layer on its exterior, and the inner surface of the bright steel pipe is smooth. The horizontal and vertical streamline bodies fixedly installed on the inner side of the bright steel pipe have the same structure. The horizontal and vertical streamline bodies are streamlined. One horizontal streamline body and one vertical streamline body constitute a group of anti-turbulence components, and there is at least a 50-centimeter gap between each group of anti-turbulence components.

[0007] Preferably, the reinforcing outer plate is a rectangular plate, and the spiral skeleton fixedly installed on the reinforcing outer plate is a spiral body. The reinforcing outer plate and the spiral skeleton are arranged in the hollow cavity.

[0008] Preferably, the hollow cavity is filled with corrosion-resistant and sound-insulating materials, and the hollow cavity is encapsulated by two flanges. The flanges are fixedly connected to the bright steel pipe and the corrosion-resistant outer cylinder.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model's anti-turbulence steel pipe has transverse and vertical streamlined bodies installed inside. These streamlined bodies guide the impending turbulence (transitional flow) through their own streamlined shape, thus slowing down its formation. Subsequent transverse and vertical streamlined bodies then guide the transitional fluid again, preventing excessive turbulence during fluid transport. Furthermore, the high-strength, corrosion-resistant outer cylinder not only increases the strength of the anti-turbulence steel pipe but also protects it from external corrosion, significantly improving its corrosion resistance and strength. This prevents damage to the anti-turbulence steel pipe due to excessive fluid pressure. Attached Figure Description

[0018] This utility model provides a high corrosion-resistant and turbulent-resistant seamless steel pipe for conveying refining fluids, comprising an anti-turbulent-flow steel pipe 1 and a high-strength corrosion-resistant outer cylinder 2. The high-strength corrosion-resistant outer cylinder 2 is fixedly installed on the outside of the anti-turbulent-flow steel pipe 1. Flanges are fixedly installed at both ends of the anti-turbulent-flow steel pipe 1 and the high-strength corrosion-resistant outer cylinder 2. The high-strength corrosion-resistant outer cylinder 2 is used to protect the anti-turbulent-flow steel pipe 1 inside itself. The anti-turbulent-flow steel pipe 1 is used to convey fluids. The high-strength corrosion-resistant outer cylinder 2 is a reinforcing corrosion-resistant component of the anti-turbulent-flow steel pipe 1.

[0019] The anti-turbulence steel pipe 1 includes a bright steel pipe 11, a horizontal streamline body 12, and a vertical streamline body 13. Several horizontal streamline bodies 12 and vertical streamline bodies 13 are fixedly installed inside the bright steel pipe 11. There is a gap between the horizontal streamline bodies 12 and the vertical streamline bodies 13. The horizontal streamline bodies 12 are horizontally fixedly installed inside the bright steel pipe 11, while the vertical streamline bodies 13 are vertically fixedly installed inside the bright steel pipe 11.

[0020] The high-strength corrosion-resistant outer cylinder 2 includes a reinforcing outer plate 21, a spiral skeleton 22, a corrosion-resistant outer cylinder 23, and a hollow cavity 24. The reinforcing outer plate 21 is fixedly installed on the bright steel pipe 11. There are four reinforcing outer plates 21. The spiral skeleton 22 is fixedly installed on the reinforcing outer plate 21. The corrosion-resistant outer cylinder 23 is fixedly installed on the outside of the four reinforcing outer plates 21. The gap between the bright steel pipe 11 and the corrosion-resistant outer cylinder 23 is the hollow cavity 24. The height of the reinforcing outer plate 21 is at least 3cm.

[0021] Example 1:

[0022] Specifically, the bright steel pipe 11 has a corrosion-resistant layer on its exterior, and the inner surface of the bright steel pipe 11 is smooth. The horizontal streamline body 12 and the vertical streamline body 13 fixedly installed inside the bright steel pipe 11 have the same structure. The horizontal streamline body 12 and the vertical streamline body 13 are streamlined. One horizontal streamline body 12 and one vertical streamline body 13 form a set of anti-turbulence components. There is at least a 50-centimeter gap between each set of anti-turbulence components. The surfaces of the horizontal streamline body 12 and the vertical streamline body 13 are smooth, and the joint connecting the horizontal streamline body 12 and the vertical streamline body 13 to the bright steel pipe 11 is an arc-shaped joint.

[0023] Specifically, the reinforcing outer plate 21 is a rectangular plate, and the spiral frame 22 fixedly installed on the reinforcing outer plate 21 is a spiral body. The reinforcing outer plate 21 and the spiral frame 22 are set in the hollow cavity 24, and the spiral frame 22 is sequentially fixedly installed on the four reinforcing outer plates 21.

[0024] Specifically, the hollow cavity 24 is filled with corrosion-resistant and sound-insulating materials. The hollow cavity 24 is enclosed by two flanges, and the flanges are fixedly connected to the bright steel pipe 11 and the corrosion-resistant outer cylinder 23.

[0025] Example 2:

[0026] When the fluid is being transported, it initially flows horizontally into the bright steel pipe 11 of the anti-turbulence steel pipe 1. As the flow velocity gradually increases, the horizontal fluid begins to oscillate, forming a transitional flow. This transitional flow then passes sequentially through the transverse streamlines 12 and vertical streamlines 13 of the bright steel pipe 11. The transverse streamlines 12 and vertical streamlines 13 guide this flow, mitigating the subsequent turbulence. Similarly, if the fluid is not in a transitional flow state and comes into contact with the transverse streamlines 12 and vertical streamlines 13, then the transverse streamlines 12 and vertical streamlines 13 will not form a transitional flow. 3 will still guide the fluid, causing the frequency and amplitude of the fluid wave oscillation to slow down, thereby reducing the occurrence of turbulent flow during the fluid transport process of the anti-turbulent steel pipe 1. In addition, external corrosion will preferentially corrode the corrosion-resistant outer cylinder 23 of the high-strength corrosion-resistant outer cylinder 2. When the corrosion-resistant outer cylinder 23 is corroded, the bright steel pipe 11 inside the corrosion-resistant outer cylinder 23 will still not be corroded, because the corrosion-resistant material filled in the hollow cavity 24 will protect it from corrosion again. At the same time, the reinforced outer plate 21 and spiral skeleton 22 will strengthen the bright steel pipe 11 of the high-strength anti-turbulent steel pipe 1.
