Description

Technical Field

[0001] This application relates to the field of pipe fixing support technology, and in particular to a pipe fixing support that can fix and support insulated pipes without damaging the insulation structure. Background Technology

[0002] Pipeline transportation is the safest and most convenient mode of heat transmission and has been widely used, especially in the field of long-distance heat transmission, bringing great convenience to people's production and life.

[0003] Pre-insulated pipes are manufactured in a factory by combining the insulation structure with the working steel pipe that transports the heating medium, creating a single integrated insulated pipe. This process offers advantages such as low production costs and convenient, quick on-site installation. However, during on-site installation, insulated pipes require fixing devices to balance pipe tension and prevent displacement. Traditional pipe support systems can cause irreversible damage to the outer protective pipe and insulation layer, reducing both the insulation and corrosion resistance of the pipe and shortening its service life. Therefore, it is necessary to propose a new technical solution to address the problems existing in current technologies. Utility Model Content

[0004] This application provides a fixed bracket for insulated pipes that does not damage the insulation structure, thereby solving the problem that traditional insulated pipe brackets reduce the insulation performance of pipes during installation.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] This application provides a fixed support for an insulated pipe that does not damage the insulation structure. It includes a fixed wing ring fixed around the periphery of a working steel pipe. A skirt is provided on each side of the fixed wing ring, and an installation gap is formed between the skirt and the working steel pipe. An outer protective pipe is installed within the installation gap. A heat insulation layer is provided between the outer wall of the outer protective pipe and the inner wall of the skirt, and a heat insulation layer is provided between the inner wall of the outer protective pipe and the outer wall of the working steel pipe. A sealing strip is wrapped around the end of the skirt away from the fixed wing ring to connect and seal the skirt and the outer protective pipe.

[0007] Furthermore, in the above technical solution, the outer protective tube is a metal tube with an inner diameter larger than that of the working steel pipe. A filling cavity for filling the insulation layer is formed between the inner wall of the outer protective tube and the outer wall of the working steel pipe. The filling cavity is filled with polyurethane foam or mineral wool.

[0008] Furthermore, the fixed wing ring is fixedly installed on the on-site fixed pier; the fixed wing ring is a metal ring structure, and the fixed wing ring is welded and fixed to the working steel pipe.

[0009] Furthermore, the skirt is a metal ring structure, with one end welded to the fixed wing ring and the other end connected to the outer protective tube through a sealing strip.

[0010] Furthermore, a heat insulation layer is provided at the connection between the outer protective tube and the fixed wing ring, and a heat insulation layer is provided at the connection between the insulation layer and the fixed wing ring.

[0011] Compared with the prior art, this application has at least the following beneficial effects:

[0012] 1. The insulated pipe fixing support provided in this application can achieve fixed support for the pipe without damaging the insulation structure. The insulated pipe fixing support is reliably connected to the working steel pipe through a fixing wing ring, and the fixing wing ring is fixed on the site fixing pier, which can ensure the stability of the pipe under thermal expansion and contraction and other external forces. In this application, skirts are welded on both sides of the fixing wing ring. A heat insulation layer, an outer protective pipe and an insulation layer are arranged in sequence between the skirt and the working steel pipe. A sealing strip is also wrapped around the end of the skirt away from the fixing wing ring. Therefore, the insulated pipe fixing support provided in this application has an outer protective pipe on both sides of the fixing wing ring. The insulation layer and the heat insulation layer ensure the insulation effect of the pipe. Moreover, this structural design will not damage the insulation structure. Compared with the transmission pipe fixing support, it ensures the insulation performance of the pipe and improves the corrosion resistance of the pipe.

[0013] 2. The insulation pipe fixing bracket provided in this application has a simple and reliable structure and is easy to install and operate. It ensures the insulation effect while maintaining structural integrity. Therefore, it can achieve heat insulation without damaging the insulation layer under high temperature operation and extend the service life of the insulation pipe. Attached Figure Description

[0018] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0020] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0021] like Figure 1 As shown, this application provides a fixed support for insulated pipes that does not damage the insulation structure. It mainly includes a fixed wing ring 5 fixed around the working steel pipe 1. During construction, the fixed wing ring 5 is fixed on the on-site fixed pier and can be cast together with the on-site fixed pier to play a fixing role.

[0022] A skirt 4 extends outward from each side of the fixed wing ring 5. The skirt 4 can be made of stainless steel and is welded to the fixed wing ring 5. The skirt 4 can be divided into two types: segmented structure and one-piece structure. In practical applications, the one-piece structure is preferred. The one-piece skirt 4 is open at both ends. One end of the skirt 4 is welded to the fixed wing ring 5, and the other end is sealed and connected to the outer protective tube 3 through the sealing strip 7.

[0023] An installation gap is pre-set between the skirt 4 and the working steel pipe 1. After the fixed wing ring 5, the skirt 4, and the working steel pipe 1 are welded together, the outer protective pipe 3 is fitted onto the working steel pipe 1, with the outer protective pipe 3 located inside the skirt 4. After the outer protective pipe 3 is installed, a heat insulation layer 2 is provided between the inner wall of the outer protective pipe 3 and the outer wall of the working steel pipe 1, and a heat insulation layer 6 is provided between the outer wall of the outer protective pipe 3 and the inner wall of the skirt 4. A heat insulation layer 6 is provided at the connection between the outer protective pipe 3 and the fixed wing ring 5, and a heat insulation layer 6 is also provided at the connection between the heat insulation layer 2 and the fixed wing ring 5. Therefore, in this application, complete heat insulation structures are provided on both sides of the fixed wing ring 5, and a heat insulation layer 6 is provided between the heat insulation structure and the fixed wing ring 5, ensuring the heat insulation effect. It can be seen that this application ensures the heat insulation characteristics and pipeline corrosion resistance while ensuring the integrity of the heat insulation structure, which can improve the service life of the pipeline.

[0024] In one embodiment, the fixed wing ring 5 in this application is made of metal material and is a ring component that can be used to fix the position of the pipeline and prevent the pipeline from axially displacing. It is welded and fixed to the fixed block and the working steel pipe 1 so that it can effectively withstand the thrust and tension generated by the pipeline due to thermal expansion and contraction or other external forces.

[0025] In one embodiment, the skirt 4 in this application is made of metal and is a ring-shaped or cylindrical structure attached to the pipe. Its main function is to enhance the connection strength between the working steel pipe 1 and the supporting structures such as the fixed wing ring 5. It also provides a certain degree of protection, preventing relative movement of the pipe on the support. In addition, the skirt 4 can also be used to distribute the weight and stress of the pipe, reducing the concentrated load on the pipe on the support.

[0026] In one embodiment, the insulation layer 2 in this application uses a high-efficiency insulation material, such as polyurethane foam or mineral wool.

[0027] In one embodiment, the outer protective tube 3 in this application is a metal tube with good corrosion resistance, such as galvanized steel tube or aluminum alloy tube.

[0028] In one embodiment, the insulation layer 6 in this application is made of a heat insulation material with low thermal conductivity, such as aluminum silicate fiber felt.

[0029] In one embodiment, both the skirt 4 and the fixed wing ring 5 in this application are made of high-strength, heat-resistant metal materials, such as carbon steel or stainless steel.

[0030] In one embodiment, the sealing tape 7 in this application is made of a sealing material with good high temperature resistance and aging resistance, such as silicone rubber tape or commercially available special sealing tape.

[0031] The installation steps for the insulated pipe fixing bracket provided in this application are as follows:

[0032] 1. Prepare materials and equipment. All required materials should be prepared according to the design specifications. Welding equipment, filling equipment, and sealing tools should also be prepared.

[0033] 2. Weld the working steel pipe to the fixed wing ring and the skirt: Weld the fixed wing ring to the target position on the working steel pipe, and weld the skirt to the fixed wing ring, leaving an installation gap between the skirt and the working steel pipe.

[0034] 3. Slide the outer protective tube onto the working steel pipe that has been welded with the fixed wing ring and skirt, ensuring that there is a sufficient gap between the outer protective tube and the fixed wing ring and skirt for filling the insulation layer.

[0035] 4. Fill the space between the outer protective tube and the fixed wing ring and skirt with heat insulation material, ensuring that the filling is uniform and without gaps, so as to achieve effective heat insulation.

[0036] 5. Use sealing tape to wrap around the hem, sealing all possible gaps and ensuring the sealing tape fits tightly to prevent air or moisture from entering.

[0037] 6. Inject insulation material (such as polyurethane foam) through the injection port of the outer protective pipe, ensuring that the insulation material fills the entire space, so that the working steel pipe, fixed wing ring, skirt, insulation layer and outer protective pipe become a whole.

[0038] 7. After the insulation material has fully cured, check the filling effect. There should be no obvious voids or unfilled areas.

[0039] 8. The fixed wing ring and the on-site fixed pier are integrated by concrete pouring, ensuring the quality and curing time of the concrete, so that the fixed wing ring is firmly connected to the fixed pier, ensuring the structural stability of the fixed pier and its ability to withstand all the working loads of the pipeline system.

[0040] In this application, a fixed wing ring is used to fix the pipe to the working steel pipe and is tightly connected with other components (such as skirts and outer protective pipes) to support the pipeline system, forming an integral structure. This tight connection method can effectively transfer the working load of the pipeline system, prevent pipeline displacement and deformation, and ensure the stability and safety of the pipeline under various conditions.

[0041] In this application, the outer protective pipe is designed in two sections, with one section on each side of the fixed wing ring. During installation, the outer protective pipe can be installed in sections after the working steel pipe and its fixed wing ring are welded together, without damaging the insulation structure and ensuring the integrity of the overall structure. The insulation pipe fixing bracket provided by this application, which does not damage the insulation structure, can provide reliable and safe support for factory-prefabricated direct-buried thermal pipelines, ensuring the insulation and corrosion resistance performance of the pipeline.

[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0043] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
