Description

Technical Field

[0001] This utility model relates to the field of seamless nickel alloy tube technology, specifically a high-temperature resistant seamless nickel alloy tube. Background Technology

[0002] Seamless nickel alloy pipe is a type of pipe made of seamless nickel alloy, combining the excellent properties of nickel alloy with the high strength and pressure resistance of seamless pipe. This type of pipe is typically used in applications requiring high temperature and pressure, strong corrosiveness, and high-purity media transmission, such as chemical, petroleum, and aerospace industries. Seamless nickel alloy pipe possesses good corrosion resistance, high-temperature strength, and oxidation resistance, making it suitable for working environments requiring high purity and high stability.

[0003] Existing seamless nickel alloy tubes cannot isolate heat when transporting high-temperature fluids, and the fluid heat is easily conducted to the environment, resulting in extremely high ambient temperatures and easy loss of fluid temperature. To address this, we propose a high-temperature resistant seamless nickel alloy tube. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant seamless nickel alloy tube that can isolate the heat of the fluid, thereby solving the problem that existing seamless nickel alloy tubes cannot isolate heat when transporting high-temperature fluids, and the heat of the fluid is easily conducted to the environment, resulting in extremely high ambient temperatures and easy loss of fluid temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant seamless nickel alloy tube, comprising a tube body and an outer ring tube, wherein a ceramic plate is installed on the outer surface of the tube body through a slot A, an outer ring tube is installed on the outer surface of the ceramic plate, a partition is installed in the gap between the ceramic plates through a clamping groove, heat insulation cotton A is filled in the gap between the partition and the outer ring tube, and heat insulation cotton B is filled in the gap between the partition and the tube body.

[0006] Preferably, there are four heat insulation cotton A in total, and the four heat insulation cotton A are evenly distributed on the inner surface of the outer ring pipe.

[0007] Preferably, there are four heat insulation cotton Bs, which are evenly distributed on the outer surface of the tube body, and the four heat insulation cotton A and heat insulation cotton Bs are staggered.

[0008] Preferably, the inner surface of the tube is provided with a high-temperature resistant coating.

[0009] Preferably, a steel wire is provided in the middle of the outer ring tube, and a total of twenty-eight steel wires are provided, which are evenly distributed in the position inside the outer ring tube.

[0010] Preferably, the inner surface of the outer ring tube is provided with a groove B at the position of the ceramic plate, and the ceramic plate is fitted into the groove B.

[0011] Preferably, there are eight ceramic plates in total, and the eight ceramic plates are evenly distributed on the outer surface of the tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves the effect of isolating the heat of the fluid by setting up a partition, heat insulation cotton A, heat insulation cotton B and an outer ring pipe. This solves the problem that existing seamless nickel alloy pipes cannot isolate heat when transporting high-temperature fluids, and the heat of the fluid is easily conducted to the environment, resulting in extremely high ambient temperature and easy loss of fluid temperature. This reduces the impact of the fluid on the ambient temperature and improves the heat preservation effect of the fluid.

[0014] 2. This utility model achieves the effect of heat insulation support for the pipe body by setting slot A, slot B and ceramic plate, so as to solve the problem that the temperature of the fluid is easily conducted to the external environment through the steel, which affects the heat preservation effect of the fluid, and reduces the temperature loss rate of the fluid, thereby ensuring the normal use of the fluid.

[0015] 3. This utility model improves the strength of the outer ring pipe by setting an outer ring pipe and steel wire, thus solving the problem that the existing outer ring pipe has low strength and is easily deformed by external impact during use, which affects the normal transport of fluid in the pipe. It reduces the probability of pipe deformation and thus ensures the normal transport of fluid. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 As shown, to achieve the above objectives, this utility model provides the following technical solution: A high-temperature resistant seamless nickel alloy tube, comprising a tube body 1 and an outer ring tube 2. A ceramic plate 10 is mounted on the outer surface of the tube body 1 via a slot A6. The outer ring tube 2 is mounted on the outer surface of the ceramic plate 10. A slot B7 is provided on the inner surface of the outer ring tube 2 at the position of the ceramic plate 10. The ceramic plate 10 is clamped inside the slot B7. A steel wire 8 is provided in the middle inside the outer ring tube 2. There are a total of twenty-eight steel wires 8, and the twenty-eight steel wires 8 are evenly distributed inside the outer ring tube 2. A partition plate 5 is installed in the gap between the ceramic plate 10 via a clamping slot 9. The gap between the partition plate 5 and the outer ring tube 2 is filled with heat insulation cotton A3. The gap between the partition 5 and the pipe body 1 is filled with heat insulation cotton B4. There are four heat insulation cotton A3s, which are evenly distributed on the inner surface of the outer ring pipe 2. There are four heat insulation cotton B4s, which are evenly distributed on the outer surface of the pipe body 1. The four heat insulation cotton A3s and heat insulation cotton B4s are staggered. The heat is isolated by the heat insulation cotton A3s and heat insulation cotton B4s, and the heat is further isolated by the staggered gaps. The inner surface of the pipe body 1 is covered with a high-temperature resistant coating 11 for initial heat isolation. There are eight ceramic plates 10, which are evenly distributed on the outer surface of the pipe body 1.

[0023] The working principle of a high-temperature resistant seamless nickel alloy tube based on Embodiment 1 is as follows: After the present invention is installed, fluid is transported through the tube body 1. At the same time, the high-temperature resistant coating 11 initially isolates the heat of the fluid. When the heat is conducted to the outer surface of the tube body 1, the heat is further isolated through the gap between the heat insulation cotton B4 and the partition plate 5. When the heat is conducted to the outer surface of the partition plate 5, the heat is isolated through the gap between the heat insulation cotton A3 and the partition plate 5, thereby reducing heat dissipation. This provides heat insulation protection for the outer ring tube 2 on the outer surface of the tube body 1, preventing the heat of the fluid from being conducted into the ambient air. Thus, the working process of this device is completed.

[0024] 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.
