Description

Technical Field

[0001] This utility model relates to the field of steel pipe noise reduction technology, specifically to a seamless noise-reducing steel pipe. Background Technology

[0002] Seamless steel pipes, as a crucial basic material in the industrial sector, are formed from round steel billets through multiple precision processing steps such as piercing and rolling. Their pipe walls exhibit a continuous, monolithic structure without welded joints. This unique manufacturing process endows them with excellent pressure-bearing capacity and structural stability. In core industrial sectors such as petrochemicals, power transmission, and machinery manufacturing, seamless steel pipes, due to their high strength and high sealing performance, are widely used in high-pressure fluid transportation pipeline systems and precision mechanical structural components.

[0003] However, in practical applications, when fluid media (such as water and gas) flow at high speeds within pipes, significant noise is inevitably generated due to fluid turbulence and pipe wall vibration. With the increasing automation and scale of industrial production, and the extended operating hours of equipment, this continuous noise pollution not only interferes with normal communication during production operations, but long-term exposure can also cause irreversible damage to the hearing system of operators. It also leads to problems such as distraction and decreased work efficiency, posing a potential threat to occupational health and safety. Therefore, effectively reducing the noise of seamless steel pipes during use has become an urgent technical challenge, requiring improvements in structure and technology to enhance noise reduction capabilities. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a seamless noise-reducing steel pipe, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A seamless noise-reducing steel pipe includes a first seamless steel pipe, on which a second seamless steel pipe is mounted by a mounting bracket;

[0007] The first seamless steel pipe has a flow guide groove inside, and the first seamless steel pipe and the second seamless steel pipe are separated into multiple installation cavities by an installation frame;

[0008] A partition frame is installed inside the mounting cavity.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the guide channels are distributed in a continuous spiral shape within the first seamless steel pipe.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The continuously spirally distributed flow channels alter the flow path of the medium (such as fluid) within the first seamless steel pipe. Compared to traditional straight-tube pipes, the medium flows along a spiral trajectory as it passes through the flow channels, extending its residence time within the pipe and resulting in a smoother flow. This effectively reduces noise generated by high-speed impact and turbulence. Simultaneously, the spiral flow channels guide and disperse the medium, preventing the formation of concentrated high-speed jets within the pipe and reducing vibrations caused by fluid turbulence, thereby further reducing noise. Furthermore, this spirally distributed flow channel can also improve the medium transport efficiency of the steel pipe to a certain extent, optimizing the pipeline's performance.

[0013] Furthermore, the partition frame is sleeved on the first seamless steel pipe, and the partition frame is set in a one-to-one correspondence with multiple mounting cavities.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The partitions are set up one-to-one with the mounting cavities, which can further divide and refine each mounting cavity, making each mounting cavity a relatively independent acoustic space. When noise propagates to the mounting cavity area, the partitions in different mounting cavities will reflect, refract, and absorb the noise multiple times. By utilizing the complex propagation path of sound waves in multiple independent cavities, the noise energy is consumed, and the noise is effectively attenuated.

[0016] Furthermore, the partition frame has several cavities arranged in a honeycomb pattern.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The honeycomb-like arrangement of cavities possesses unique acoustic characteristics. Its regular and dense chamber structure provides excellent conditions for noise absorption and dissipation. When noise enters the cavity, sound waves continuously reflect and interfere between the various chambers. Due to the specific relationship between the size of the honeycomb structure and the wavelength of the noise, a resonance effect can be triggered, allowing the noise energy to be efficiently converted into other forms of energy such as heat, thereby significantly reducing the noise intensity.

[0019] Furthermore, the cavity is filled with sound-absorbing cotton material.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] Sound-absorbing cotton material possesses excellent porosity and fibrous structure, effectively absorbing noise of different frequencies. When noise enters the cavity filled with sound-absorbing cotton, the sound waves cause the fibers within the cotton to vibrate. Due to friction and viscous resistance between the fibers, the energy of the sound waves is converted into heat and dissipated. The sound-absorbing cotton material has a significant absorption effect on high-frequency noise, which, combined with the absorption of mid-to-low-frequency noise by the honeycomb cavity, forms a comprehensive noise reduction capability across the entire frequency range, greatly enhancing the noise reduction performance of seamless noise-reducing steel pipes. Furthermore, the sound-absorbing cotton material also has a certain buffering and shock-absorbing effect, reducing mechanical vibrations caused by internal medium flow or external vibrations within the steel pipe, further reducing vibration-induced noise, and also providing some protection for the internal structure of the steel pipe.

[0022] This utility model provides a seamless noise-reducing steel pipe. It has the following beneficial effects:

[0023] The guide channels are distributed in a continuous spiral pattern within the first seamless steel pipe, altering the flow path of the medium, extending its residence time within the pipe, resulting in smoother flow and reducing noise caused by high-speed impact and turbulence. Simultaneously, they guide and disperse the medium, preventing the formation of concentrated high-speed jets and reducing vibrations caused by fluid turbulence, thereby lowering noise. Furthermore, they can improve the medium transport efficiency of the steel pipe to a certain extent and optimize pipeline performance.

[0024] The partition frame is fitted onto the first seamless steel pipe and corresponds one-to-one with multiple mounting cavities, further dividing and refining each mounting cavity to form relatively independent acoustic spaces. When noise propagates to the mounting cavity area, the partition frame will reflect, refract, and absorb the noise multiple times, utilizing the complex propagation path of sound waves in multiple independent cavities to consume noise energy and achieve effective noise attenuation.

[0025] The partition frame contains honeycomb-shaped cavities, whose regular and dense structure provides excellent conditions for noise absorption and dissipation. When noise enters the cavities, the sound waves reflect and interfere continuously between the cavities, triggering a resonance effect that efficiently converts noise energy into heat and other forms of energy, significantly reducing noise intensity.

[0026] The cavity is filled with sound-absorbing cotton material. The porous and fibrous structure of the sound-absorbing cotton effectively absorbs noise of different frequencies. Sound waves cause the fibers within the sound-absorbing cotton to vibrate, and the sound wave energy is dissipated as heat energy through friction and viscous resistance between the fibers. The sound-absorbing cotton has a significant effect on absorbing high-frequency noise, and combined with the absorption of mid- and low-frequency noise by the honeycomb cavity, it forms a comprehensive noise reduction capability across the entire frequency range, greatly improving the noise reduction performance of the seamless noise-reducing steel pipe.

[0036] 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.

[0037] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A seamless noise-reducing steel pipe includes a first seamless steel pipe 1, and a second seamless steel pipe 2 is mounted on the first seamless steel pipe 1 via a mounting bracket 201.

[0040] The first seamless steel pipe 1 has a guide groove 101 inside, and the first seamless steel pipe 1 and the second seamless steel pipe 2 are separated into multiple installation cavities 203 by the mounting frame 201.

[0041] A partition frame 202 is installed inside the mounting cavity 203;

[0042] The guide channels 101 are distributed in a continuous spiral shape within the first seamless steel pipe 1. This continuous spiral distribution alters the flow path of the medium (such as fluid) within the first seamless steel pipe 1. Compared to traditional straight-tube pipes, the medium flows along a spiral trajectory as it passes through the guide channels 101, extending its residence time within the pipe and resulting in smoother flow. This effectively reduces noise generated by high-speed impact and turbulence of the medium. Simultaneously, the spiral shape of the guide channels 101 guides and disperses the medium, preventing the formation of concentrated high-speed jets within the pipe and reducing vibrations caused by fluid turbulence, thereby further reducing noise. Furthermore, this spiral distribution of the guide channels 101 can also improve the medium transport efficiency of the steel pipe to a certain extent, optimizing the pipe's performance.

[0043] Example 2

[0044] To further enhance the noise reduction effect of the steel pipe, noise is reduced through the cooperation of multiple cavities, for example, such as... Figures 1 to 5 As shown, this utility model also includes:

[0045] The partition frame 202 is sleeved on the first seamless steel pipe 1, and the partition frame 202 is set one-to-one with multiple mounting cavities 203. The one-to-one setting of the partition frame 202 and the mounting cavity 203 can further divide and refine each mounting cavity 203, so that each mounting cavity 203 forms a relatively independent acoustic space. When noise propagates to the area of ​​the mounting cavity 203, the partition frame 202 in different mounting cavities will reflect, refract and absorb the noise multiple times. By utilizing the complex propagation path of sound waves in multiple independent cavities, the noise energy is consumed, and the noise is effectively attenuated.

[0046] The partition 202 contains several honeycomb-shaped cavities 204. These honeycomb cavities 204 possess unique acoustic characteristics; their regular and dense chamber structure provides excellent conditions for noise absorption and dissipation. When noise enters the cavity 204, sound waves continuously reflect and interfere between the chambers. Due to the specific relationship between the size of the honeycomb structure and the noise wavelength, a resonance effect is triggered, allowing noise energy to be efficiently converted into heat or other forms of energy, thereby significantly reducing noise intensity.

[0047] The cavity 204 is filled with sound-absorbing cotton material. This material has excellent porosity and a fibrous structure, effectively absorbing noise of different frequencies. When noise enters the cavity 204 filled with sound-absorbing cotton, the sound waves cause the fibers within the cotton to vibrate. Due to friction and viscous resistance between the fibers, the energy of the sound waves is converted into heat and dissipated. The sound-absorbing cotton material has a significant absorption effect on high-frequency noise. Combined with the absorption effect of the honeycomb cavity 204 on mid- and low-frequency noise, it forms a comprehensive noise reduction capability across the entire frequency range, greatly improving the noise reduction performance of the seamless noise-reducing steel pipe. Furthermore, the sound-absorbing cotton material also has a certain buffering and shock-absorbing effect, reducing mechanical vibrations caused by internal medium flow or external vibrations in the steel pipe, further reducing noise caused by vibration, and also providing some protection for the internal structure of the steel pipe.

[0048] Working principle:

[0049] The medium enters the guide channel 101 inside the first seamless steel pipe 1. Because the guide channel 101 is distributed in a continuous spiral shape, the medium moves along the spiral trajectory, prolonging its residence time in the pipe and making the flow smoother, thus reducing noise caused by high-speed impact and turbulence. At the same time, the spiral-shaped guide channel 101 guides and disperses the medium, preventing the formation of concentrated high-speed jets, reducing vibration caused by fluid turbulence, further reducing noise, and optimizing the medium transportation efficiency.

[0050] When noise is generated and propagates to the mounting cavity 203 area between the first seamless steel pipe 1 and the second seamless steel pipe 2, the partition frames 202, which are arranged one-to-one with the mounting cavities 203, divide each mounting cavity 203 into a relatively independent acoustic space. When the noise propagates in these independent cavities, it will be reflected, refracted, and absorbed multiple times by the partition frames 202. Through the propagation of sound waves in a complex path, the noise energy is consumed, and initial attenuation is achieved.

[0051] The noise further penetrates into the honeycomb-shaped cavities 204 within the partition 202. Due to the specific relationship between the size of the honeycomb structure and the wavelength of the noise, a resonance effect is triggered. The sound waves continuously reflect and interfere between the various cavities, and the noise energy is efficiently converted into other forms of energy such as heat, significantly reducing the noise intensity.

[0052] The sound-absorbing cotton filling the cavity 204 plays a crucial role; its excellent porosity and fibrous structure effectively absorb noise of different frequencies. When sound waves enter the cavity 204, they cause the fibers within the sound-absorbing cotton to vibrate. The friction and viscous resistance between the fibers convert the sound wave energy into heat energy, which is then dissipated. The significant absorption effect of the sound-absorbing cotton on high-frequency noise, combined with the absorption of mid- and low-frequency noise by the honeycomb-shaped cavity 204, creates a comprehensive noise reduction capability across the entire frequency range. Furthermore, the buffering and vibration damping effects of the sound-absorbing cotton reduce the mechanical vibration of the steel pipe caused by internal medium flow or external vibrations, lowering vibration-induced noise while protecting the internal structure of the steel pipe.
