Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe technology, specifically to a large-diameter nickel alloy seamless pipe with impact resistance. Background Technology

[0002] Seamless steel pipe is a type of steel pipe without welded joints, typically produced through solid-state pressure processing or rotary machining. This type of pipe has no obvious weld seams, thus possessing high strength and pressure resistance, making it suitable for various high-pressure, high-temperature, or critical engineering and applications. Seamless steel pipes are commonly used in petroleum, chemical, natural gas, heating, and water supply industries, and are highly favored for their excellent sealing and corrosion resistance.

[0003] Existing seamless steel pipes have poor pressure resistance and are prone to deformation under the influence of high fluid impact, which can lead to fluid leakage and affect the normal transport of fluid. To address this, we propose a large-diameter nickel alloy seamless pipe with impact resistance. Utility Model Content

[0004] The purpose of this invention is to provide a large-diameter nickel alloy seamless pipe that is impact-resistant and has the effect of absorbing fluid pressure, thereby protecting the seamless steel pipe. This solves the problem that existing seamless steel pipes have poor pressure resistance and are prone to deformation under the influence of high fluid impact, which leads to fluid leakage and affects the normal transportation of fluid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter nickel alloy seamless tube with impact resistance, comprising a tube body and a pressure-resistant tube, wherein the pressure-resistant tube is installed on the outer surface of the tube body via a support ring, a support plate is installed at the gap position of the support ring, a positioning frame is installed on the outer surface of the support plate, and a damping pad A is installed at the gap position between the support plate and the tube body.

[0006] Preferably, damping pads B are provided inside the pressure-resistant tube at the positions of the support plate and the positioning frame.

[0007] Preferably, a support frame is installed at the bottom of the support plate, and the support frame is connected to the outer surface of the tube.

[0008] Preferably, the inner surface of the tube is provided with a corrosion-resistant coating, and the outer surface of the pressure-resistant tube is provided with an anti-rust coating.

[0009] Preferably, the tube body and the pressure-resistant tube are provided with a groove near the support ring, and the support ring is fitted into the groove.

[0010] Preferably, the support ring has a cross bracket inside, and a damping band is provided inside the support ring at the gap position of the cross bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model achieves the effect of absorbing fluid pressure and protecting the seamless steel pipe by setting up a pressure-resistant pipe, a support ring, a support plate and a damping pad A. This solves the problem that the existing seamless steel pipe has poor pressure resistance and is prone to deformation under the influence of high fluid impact, which leads to fluid leakage and affects the normal transportation of fluid. It reduces the probability of deformation of the seamless steel pipe and thus ensures the normal transportation of fluid.

[0013] 2. This utility model achieves the effect of absorbing external impact force by setting up a pressure-resistant pipe, positioning frame, support plate and damping pad B, so as to solve the problem that existing seamless steel pipes are mostly buried in the ground and are greatly affected by ground pressure. When the ground pressure is too high, the pipe body is easy to deform and be damaged. This reduces the probability of pipe deformation and thus ensures the normal transportation of fluid.

[0014] 3. This utility model achieves the effect of protecting the pipe body by setting corrosion-resistant coating and anti-rust coating, thereby solving the problem that existing seamless steel pipes are easily corroded by fluids during fluid transportation, affecting the service life of seamless steel pipes, reducing the probability of rusting of seamless steel pipes, and thus improving the service life of seamless steel pipes.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-3As shown, to achieve the above objectives, this utility model provides the following technical solution: a large-diameter nickel alloy seamless tube with impact resistance, comprising a tube body 1 and a pressure-resistant tube 5. The pressure-resistant tube 5 is installed on the outer surface of the tube body 1 via a support ring 3. A support plate 2 is installed at the gap position of the support ring 3. A positioning frame 10 is installed on the outer surface of the support plate 2. A damping pad A7 is installed at the gap position between the support plate 2 and the tube body 1. Damping pads B9 are provided inside the pressure-resistant tube 5 at the positions of the support plate 2 and the positioning frame 10. A support frame 8 is installed at the bottom of the support plate 2 and is connected to the outer surface of the tube body 1. A corrosion-resistant coating 6 is provided on the inner surface of the tube body 1. A rust-proof coating 11 is provided on the outer surface of the pressure-resistant tube 5. A slot 4 is provided near the support ring 3 on the tube body 1 and the pressure-resistant tube 5, and the support ring 3 is fitted into the slot 4.

[0023] The working principle of a shock-resistant large-diameter nickel alloy seamless pipe based on Embodiment 1 is as follows: After the present invention is installed, multiple sets of the present invention are connected together. Fluid is transported through the pipe body 1, and the pipe body 1 is protected by the pressure-resistant pipe 5. When the fluid pressure inside the pipe body 1 is too high, the fluid pressure is absorbed by the support frame 8 and the damping pad A7. At the same time, the support plate 2 is supported by the positioning frame 10, thereby supporting and protecting the pipe body 1. When the external pressure impact is too high, the external impact is initially absorbed by the positioning frame 10 and the damping pad B9, and then the external impact is absorbed again by the support plate 2 and the damping pad A7, thereby protecting the pipe body 1. At this point, the working process of the equipment is completed.

[0024] Example 2

[0025] like Figure 2 and Figure 4 As shown, the present invention proposes an impact-resistant large-diameter nickel alloy seamless tube. Compared with Embodiment 1, this embodiment further includes: a cross bracket 13 is provided inside the support ring 3, and a damping band 12 is provided inside the support ring 3 at the gap position of the cross bracket 13.

[0026] In this embodiment, during use, the cross bracket 13 provides support for the pressure-resistant tube 5, and the cross bracket 13 and damping band 12 inside the support ring 3 provide support for the support ring 3, thereby improving the support strength of the support ring 3 and thus improving the support strength of the pressure-resistant tube 5.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
