Description

Technical Field

[0001] This utility model relates to a seamless steel pipe device, specifically a high-strength support type seamless steel pipe, belonging to the field of steel technology. Background Technology

[0002] Seamless steel pipes have a hollow cross section and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight while maintaining the same bending and torsional strength, making them an economical type of steel material.

[0003] A search revealed Chinese patent CN216045886U, which discloses a high-strength seamless steel pipe. This pipe provides cushioning against impacts and significant forces, reducing the impact on the pipe body and ensuring its efficiency and lifespan. The annular reinforcing block within the first cushioning cavity, along with several circular support blocks on top of it, further enhances the internal strength of the pipe. However, while the patented product uses a cushioning spring for shock absorption, prolonged use can lead to deformation of the bottom spring due to compression, reducing its effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength support-type seamless steel pipe to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a high-strength support-type seamless steel pipe, comprising a steel pipe body, an outer shell on the outermost side of the steel pipe body, an insulation layer inside the outer shell, a first inner ring on the side of the insulation layer away from the outer shell, a second inner ring inside the steel pipe body, a plurality of trapezoidal shock-absorbing blocks staggered between the first inner ring and the second inner ring, a plurality of reinforcing ribs equidistantly arranged inside the insulation layer, connecting rods corresponding to the sides of the outer shell and the first inner ring, and a connecting plate between two connecting rods.

[0006] Preferably, a fixing rod is provided in the middle of the interior of the steel pipe body. The fixing rod is arranged in a star shape with one end fixed inside the second inner ring and the other end located at the center of the second inner ring.

[0007] Preferably, three inner rings are provided at equal intervals from the inside to the outside on the five fixed rods, and the inner rings are arranged in an arc shape on both sides facing the two ends of the steel pipe body.

[0008] Preferably, the length and orientation of the reinforcing rib are consistent with the main body of the steel pipe.

[0009] Preferably, the connecting rod is fixed to the outer shell and the first inner ring, the connecting plate is movably connected to the connecting rod, and the end of the connecting rod away from the outer shell and the first inner ring is arranged in a "T" shape.

[0010] The beneficial effects of this utility model are as follows: In the above-mentioned existing patented products, the buffer spring is used to dampen the steel pipe body. However, after long-term use, the buffer spring located at the bottom end is easily deformed due to prolonged compression, which leads to a reduction in the subsequent buffering effect. This utility model adds reinforcing ribs and trapezoidal damping blocks to the seamless steel reinforcement structure, which alleviates the problem of deformation of traditional damping springs after long-term use. At the same time, the internal star-shaped fixing rod can disperse the internal and external pressure on the pipe, reduce the deformation, bending or local collapse of the pipe caused by uneven pressure, and extend the service life of the pipe.

[0016] 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.

[0017] Please see Figure 1-4As shown, a high-strength support type seamless steel pipe includes a steel pipe body 1, an outer shell 2 on the outermost side of the steel pipe body 1, an insulation layer 203 inside the outer shell 2, a first inner ring 201 on the side of the insulation layer 203 away from the outer shell 2, a second inner ring 204 inside the steel pipe body 1, a plurality of trapezoidal damping blocks 205 are staggered between the first inner ring 201 and the second inner ring 204, a plurality of reinforcing ribs 202 are equidistantly arranged inside the insulation layer 203, connecting rods 206 are provided on the sides of the outer shell 2 and the first inner ring 201 respectively, and a connecting plate 207 is provided between the two connecting rods 206.

[0018] The steel pipe body 1 has a fixing rod 3 in the middle of its interior. The fixing rod 3 is arranged in a star shape. One end of the fixing rod 3 is fixed inside the second inner ring 204, and the other end of the fixing rod 3 is located at the center of the second inner ring 204. Three inner rings 301 are equally spaced from the inside to the outside on the five fixing rods 3. The inner rings 301 are arranged in an arc shape on both sides facing the two ends of the steel pipe body 1.

[0019] According to the above embodiments, it should be noted that: a multi-layer structure is added to the internal structure of the seamless steel pipe body 1. When transporting liquids over long distances, the liquid is loaded inside the second inner ring 204 of the steel pipe body 1. During transportation, the liquid sloshes, and the second inner ring 204 vibrates. At this time, the trapezoidal damping blocks 205 located between the second inner ring 204 and the first inner ring 201 intersect and shift, thus damping the sloshing of the liquid inside the steel pipe body 1. At the same time, when the second inner ring 204 inside vibrates, the first inner ring 201 is vibrated, compressing the insulation layer 203. The reinforcing ribs 202 enhance the overall strength of the steel pipe body 1. The reinforcing ribs 202 are combined with the star-shaped fixing rods 3 inside the steel pipe body 1 to avoid deformation, bending or local collapse of the pipeline due to uneven pressure.

[0020] The arc-shaped arrangement on both sides of the inner ring 301 can guide the flow direction of the fluid (liquid or gas) in the pipe, reduce turbulence and eddies caused by excessive flow velocity or changes in pipe cross-section, reduce friction loss, and improve conveying efficiency.

[0021] Please see Figure 1-4 As shown, a high-strength support type seamless steel pipe includes a reinforcing rib 202 whose length and direction are consistent with the main body 1 of the steel pipe. A connecting rod 206 is fixed on the outer shell 2 and the first inner ring 201. A connecting plate 207 is movably connected to the connecting rod 206. The end of the connecting rod 206 away from the outer shell 2 and the first inner ring 201 is set in a "T" shape.

[0022] According to the above embodiments, it should be noted that: a connecting rod 206 and a connecting plate 207 are added between the outer shell 2 and the first inner ring 201 to further strengthen the fixation between the outer shell and the first inner ring 201 and improve the overall strength.

[0023] In summary, the operating procedure of this device is as follows: a multi-layer structure is added to the internal structure of the seamless steel pipe body 1. During long-distance liquid transportation, the liquid is loaded inside the second inner ring 204 of the steel pipe body 1. During transportation, the liquid sloshes, and the second inner ring 204 vibrates. At this time, the trapezoidal damping blocks 205 located between the second inner ring 204 and the first inner ring 201 intersect and shift, thus damping the sloshing of the liquid inside the steel pipe body 1. At the same time, when the second inner ring 204 inside vibrates, the first inner ring 201 is vibrated, compressing the insulation layer 203. The reinforcing ribs 202 enhance the overall strength of the steel pipe body 1. The reinforcing ribs 202 are combined with the star-shaped fixing rods 3 inside the steel pipe body 1 to avoid deformation, bending or local collapse of the pipeline due to uneven pressure.

[0024] The arc-shaped arrangement on both sides of the inner ring 301 can guide the flow direction of the fluid (liquid or gas) in the pipe, reduce turbulence and eddies caused by excessive flow velocity or changes in pipe cross-section, reduce friction loss, and improve conveying efficiency.

[0025] A connecting rod 206 and a connecting plate 207 are added between the outer shell 2 and the first inner ring 201 to further strengthen the fixation between the outer shell and the first inner ring 201 and improve the overall strength.
