Description

Technical Field

[0001] This utility model relates to the field of high-pressure pipe technology, specifically to a flame-retardant and aging-resistant high-pressure pipe. Background Technology

[0002] In industries such as petrochemicals and heat transmission, high-pressure pipes are crucial components for transporting high-temperature and high-pressure media. With the continuous expansion of industrial production scale and increasingly stringent process requirements, higher demands are placed on the performance of high-pressure pipes, especially in terms of high-temperature resistance and explosion prevention. Existing high-pressure pipes are prone to combustion when exposed to high temperatures or open flames, which can lead not only to pipe rupture and fluid leakage but also to serious safety accidents such as fires and explosions. Furthermore, in terms of aging resistance, high-pressure pipes exposed to outdoor environments for extended periods are affected by factors such as ultraviolet radiation, oxygen, and temperature changes. This causes the materials to gradually age and degrade, resulting in decreased pipe strength, reduced flexibility, cracks, and damage, thus shortening the service life of the high-pressure pipes.

[0003] Based on the above, this utility model proposes a flame-retardant and aging-resistant high-pressure pipe, which can effectively solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a flame-retardant and aging-resistant high-pressure pipe.

[0005] This utility model is achieved through the following technical solution:

[0006] A flame-retardant and aging-resistant high-pressure pipe includes an inner tube body, an insulation layer disposed on the outer side of the inner tube body, an outer tube body disposed on the outer side of the insulation layer, and the inner side of the outer tube body having a first cavity and a second cavity arranged sequentially from the inside to the outside; the first cavity is filled with a first flame-retardant inner core; the second cavity is filled with a second flame-retardant inner core; and the outer surface of the outer tube body is coated with an anti-aging coating.

[0007] According to the above technical solution, as a further preferred technical solution, both the inner tube and the outer tube are made of polyethylene.

[0008] According to the above technical solution, as a further preferred technical solution, the heat insulation layer is made of ceramic fiber.

[0009] According to the above technical solution, as a further preferred technical solution, the first flame-retardant inner core is an asbestos mesh, and the second flame-retardant inner core is a mica board.

[0010] According to the above technical solution, as a further preferred technical solution, the anti-aging coating is acrylic resin.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] This utility model provides a flame-retardant and aging-resistant high-pressure pipe. By setting a first flame-retardant inner core and a second flame-retardant inner core inside the outer pipe body, it can prevent the high-pressure pipe from burning when the external temperature is too high, and the flame-retardant effect is good. At the same time, a heat insulation layer is set between the inner and outer pipe bodies, which can effectively block the heat generated by the outside from being transferred to the inside, and prevent the medium transported in the high-pressure pipe from being heated and affecting its performance. In addition, an anti-aging coating is applied to the outer surface of the outer pipe body, which can enhance the resistance of the outer pipe body to aging caused by environmental factors and further extend the service life of the high-pressure pipe.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0015] A flame-retardant and aging-resistant high-pressure pipe includes an inner tube body 1, an insulation layer 2 disposed on the outer side of the inner tube body 1, and an outer tube body 3 disposed on the outer side of the insulation layer 2. The outer tube body 3 has a first cavity 31 and a second cavity 32 arranged sequentially from the inside to the outside. The first cavity 31 is filled with a first flame-retardant inner core 4. The second cavity 32 is filled with a second flame-retardant inner core 5. The outer surface of the outer tube body 3 is coated with an anti-aging coating 6.

[0016] This invention, by setting a first flame-retardant inner core 4 and a second flame-retardant inner core 5 inside the outer tube body 3, can prevent the high-pressure pipe from burning when the external temperature is too high, and has a good flame-retardant effect; at the same time, a heat insulation layer 2 is set between the inner tube body 1 and the outer tube body 3, which can effectively block the heat generated by the outside from being transferred to the inside, and prevent the medium transported in the high-pressure pipe from being heated and affecting its performance; at the same time, an anti-aging coating 6 is coated on the outer surface of the outer tube body 3, which can enhance the resistance of the outer tube body 3 to aging caused by environmental factors, and further extend the service life of the high-pressure pipe.

[0017] Furthermore, in another embodiment, both the inner tube 1 and the outer tube 3 are made of polyethylene.

[0018] By using an inner tube 1 and an outer tube 2 made of polyethylene, the high-pressure pipe has good flexibility, corrosion resistance and impact resistance. This makes it less susceptible to corrosion by the medium being transported while it can withstand a certain pressure, and it is not easily damaged when subjected to external impact. This improves the durability and stability of the high-pressure pipe and reduces maintenance costs.

[0019] Furthermore, in another embodiment, the heat insulation layer 2 is made of ceramic fiber.

[0020] By setting up a heat insulation layer 2 made of ceramic fiber, the ceramic fiber has excellent heat insulation performance and can effectively block the heat generated by the outside from being transferred to the inside, thus preventing the medium transported in the high-pressure pipe from being heated and affecting its performance.

[0021] Furthermore, in another embodiment, the first flame-retardant inner core 4 is an asbestos mesh, and the second flame-retardant inner core 5 is a mica board.

[0022] By setting a first flame-retardant inner core 4 made of asbestos mesh and a second flame-retardant inner core 5 made of mica board, the flame-retardant performance of the high-pressure pipe is improved. When the outside temperature is too high, it can prevent the high-pressure pipe from burning, thus increasing safety.

[0023] Furthermore, in another embodiment, the anti-aging coating 6 is an acrylic resin.

[0024] The anti-aging coating made of acrylic resin has good weather resistance, UV resistance and chemical stability, which can effectively prevent the outer tube from aging and degrading due to long-term exposure to outdoor environment factors such as ultraviolet rays, oxygen and water vapor, thus extending the service life of the high-pressure tube and maintaining its appearance and performance stability.
