Description

Technical Field

[0001] This utility model relates to the field of pipe technology, and in particular to a high-temperature and corrosion-resistant pipe. Background Technology

[0002] Pipes are the materials used to make pipe fittings. Different pipe fittings require different pipe materials. The quality of the pipe material directly determines the quality of the pipe fittings. Corrosion resistance is an important indicator for measuring the quality of pipe materials. With the rapid development of plastic pipes, the quality is also constantly improving. A plastic pipe industry mainly based on polyvinyl chloride (PVC) pipes and polypropylene (PP) pipes has been initially formed. Among them, polyethylene (PE) pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission and distribution, gas transmission pipes, electrical and telecommunications protection sleeves, industrial pipes, and agricultural pipes due to their unique advantages. They are mainly used in urban water supply, urban gas supply, and farmland irrigation.

[0003] Publication No.: CN202181707U, Stainless Steel Filled Pipe, comprising a stainless steel pipe, small-particle concrete, and reinforcing steel bars. The stainless steel pipe is the outer shell, which can be cylindrical, square, rhomboid, or other geometric shapes. Small-particle concrete is filled into the hollow interior of the stainless steel pipe. Reinforcing steel bars are embedded within the small-particle concrete in the stainless steel pipe; at least one reinforcing steel bar should be included, and the number of bars can be appropriately increased or decreased depending on the diameter of the stainless steel pipe. The stainless steel filled pipe described in this utility model has a simple overall structure, is easy to operate and use, has good stability, and high reliability. Using the stainless steel filled pipe described in this utility model can reduce costs while ensuring compliance with the strength requirements of stainless steel pipes, and can be widely used in the decoration and renovation industry. However, the following problems may arise in practical use:

[0004] 1) Due to the poor corrosion resistance of existing pipes, the pipes are prone to corrosion damage after a period of use, causing them to lose their original functions and reducing their practicality and applicability.

[0005] 2) Because the pipe surface is smooth, there are fewer contact points for the corrosion-resistant material brushed onto the pipe. As a result, the corrosion-resistant material on the surface of the pipe will peel off during long-term use. This allows liquid to continuously penetrate between the coating and the pipe from the peeled-off parts, causing the coating to peel off from the pipe and leading to corrosion on the pipe surface. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a high-temperature and corrosion-resistant pipe to solve the problem that the corrosion-resistant layer on the surface of current pipes is prone to peeling off during long-term use, leading to pipe corrosion, and that the materials used in the pipes are usually plastics, mainly polyvinyl chloride and polypropylene, which have poor high-temperature resistance.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A high-temperature and corrosion-resistant pipe includes a main pipe, a heat dissipation mechanism fixedly installed on the outer surface of the main pipe, and an outer protective mechanism fixedly installed on the outer surface of the heat dissipation mechanism.

[0010] The outer protective mechanism includes an outer coating layer, a connecting mesh frame is fixedly installed on the inner surface of the outer coating layer, and a clamping rod is fixedly installed on the inner surface of the connecting mesh frame.

[0011] As an improved technical solution, the heat dissipation mechanism includes a first connecting pipe, and a support frame is fixedly installed on the outer surface of the first connecting pipe.

[0012] As an improved technical solution, a second connecting pipe is fixedly installed on the outer surface of the support frame, and a slot is formed on the outer surface of the second connecting pipe.

[0013] As an improved technical solution, the inner surface of the support frame is provided with a connecting groove.

[0014] As an improved technical solution, the inner surface of the first connecting pipe is fixedly connected to the outer surface of the main pipe.

[0015] As an improved technical solution, the inner surface of the slot is engaged with the outer surface of the lever.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model improves the adhesion of the pipe coating by using a design that ensures a good seal. The outer coating is fully in contact with the connecting mesh frame through the cooperation of the outer coating and the connecting mesh frame. The cooperation of the connecting mesh frame, the clamp rod, the clamp groove, and the second connecting pipe fixes the outer coating onto the connecting mesh frame. This prevents the corrosion-resistant coating from peeling off after long-term use, which would expose the pipe to the air and cause corrosion at the exposed parts, thus increasing the service life of the pipe.

[0018] 2. This utility model improves the high-temperature resistance of the pipe by adding a high-temperature resistance design. Through the use of the outer coating, the connecting mesh frame and the second connecting pipe, and the use of the second connecting pipe and the support frame, the first connecting pipe and the connecting groove, air is connected inside the pipe. The external cold air and the internal hot air meet and flow, transferring the heat inside the pipe and reducing the internal temperature of the pipe, thereby improving the high-temperature resistance of the pipe.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0030] like Figure 1 Figure 2 and Figure 3 As shown in the figure, this embodiment provides a high temperature and corrosion resistant pipe, which includes a main pipe 1, a heat dissipation mechanism 2 fixedly installed on the outer surface of the main pipe 1, and an outer protective mechanism 3 fixedly installed on the outer surface of the heat dissipation mechanism 2.

[0031] The outer protective mechanism 3 includes an outer coating 31, a connecting frame 32 is fixedly installed on the inner surface of the outer coating 31, and a clamping rod 33 is fixedly installed on the inner surface of the connecting frame 32.

[0032] The outer coating 31 is a high-temperature and corrosion-resistant coating material. This coating material refers to a material that can withstand high-temperature environments for a long time and maintain certain physical and chemical properties. These materials typically possess characteristics such as high-temperature resistance, corrosion resistance, and wear resistance. The main components of this coating material include glass flakes, resin, curing agent, and additives. Glass flakes have good acid and alkali resistance, corrosion resistance, and wear resistance, while the resin acts as a binder. The curing agent and additives are used to adjust the performance of the coating.

[0033] The connecting frame 32 is made of fiberglass, which creates multiple gaps within the frame, allowing the resin in the outer coating 31 to make full contact. Under the catalysis of the curing agent, the resin begins to produce a solid polymer, gradually loses its adhesiveness, and eventually cures completely onto the connecting frame 32, thus ensuring that the outer coating 31 is tightly fixed to the connecting frame 32.

[0034] like Figure 1, Figure 2 and Figure 4 As shown, the heat dissipation mechanism 2 includes a first connecting pipe 21, and a support frame 22 is fixedly installed on the outer surface of the first connecting pipe 21.

[0035] Multiple support frames 22 form a ventilation channel, allowing internal heat to be carried away by the wind.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, a second connecting pipe 23 is fixedly installed on the outer surface of the support frame 22, and a slot 24 is opened on the outer surface of the second connecting pipe 23.

[0037] like Figure 1 and Figure 4 As shown, the inner surface of the support frame 22 is provided with a connecting groove 25.

[0038] The connecting groove 25 can connect the ventilation channels formed by multiple support frames 22, and the gas in the ventilation duct can communicate with each other.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, the inner surface of the first connecting pipe 21 is fixedly connected to the outer surface of the main pipe 1.

[0040] The main pipe 1 is made of plastic, which, after softening, can be fully fixed to the first connecting pipe 21.

[0041] like Figure 1 and Figure 2 As shown, the inner surface of the slot 24 engages with the outer surface of the lever 33.

[0042] The slot 24 and the lever 33 engage with each other, fixing the connecting frame 32 onto the second connecting pipe 23, thereby preventing the connecting frame 32 from falling off the second connecting pipe 23.

[0043] In use, the user first places the first connecting pipe 21 and the second connecting pipe 23, each equipped with a support frame 22, onto the outer surface of the main pipe 1. Then, the clamping rod 33 of the connecting frame 32 is inserted into the groove 24 of the second connecting pipe 23, fixing the connecting frame 32 onto the second connecting pipe 23. Next, glass flakes, resin, curing agent, and additives are mixed to form an outer coating 31. The outer coating 31 is then applied to the connecting frame 32, ensuring that the resin in the outer coating 31 is fully adhered to the connecting frame 32. After the outer coating 31 cures, it will not peel off even after long-term use. The outer coating 31 also exhibits high temperature resistance and corrosion resistance. This is because the first connecting pipe 21 and the second connecting pipe 23 contain multiple supports. The frame 22 has connectors at both ends of the pipe for connecting other pipes. These connectors can connect two pipes and also allow dehumidified outside air to enter the ventilation duct between connecting pipe 21 and connecting pipe 23. When there is high temperature outside the pipe, some of the temperature will be transferred to connecting pipe 21 and connecting pipe 23, making the air inside connecting pipe 21 and connecting pipe 23 hot. This causes the air inside connecting pipe 21 and connecting pipe 23 to start flowing, allowing the outside cold air to pass through the connector first, be dehumidified by the dehumidification device inside the connector, and then be poured into connecting pipe 21 and connecting pipe 23, transferring heat out and thus reducing the temperature inside the pipe, thereby improving the high temperature resistance of the pipe.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
