[0002] In steam transmission systems, steam pipelines need to have good insulation, corrosion resistance, impact resistance and convenient installation and maintenance characteristics. However, some existing steam pipelines have unreasonable structural design, resulting in problems such as poor insulation effect, susceptibility to corrosion, weak impact resistance and inconvenience in installation and relocation.
[0003] Existing steam pipe assemblies are equipped with insulation and flame-retardant layers, but the insulation layer is a single structure with significant heat loss and no dedicated buffer structure. When the pipe is subjected to external impact or vibration, it is easily damaged due to its strong structural rigidity. At the same time, the lack of convenient moving and adjusting components during installation leads to high labor intensity and low efficiency during installation and maintenance. Therefore, a new type of steam pipe assembly needs to be designed to solve the above problems. Utility Model Content

[0009] Preferably, the inner tube, inner anti-corrosion layer, thermal insulation layer, heat insulation layer, flame retardant layer, buffer component and outer anti-corrosion layer are arranged coaxially and the layers are tightly bonded to each other, and the two rolling components are symmetrically distributed on both sides of the outer surface of the outer anti-corrosion layer.
[0010] Preferably, the plurality of X-shaped buffer reinforcing ribs are evenly distributed on the inner wall of the buffer layer, and the included angle between two adjacent X-shaped buffer reinforcing ribs is equal.
[0011] Preferably, the intersection of the X-shaped buffer reinforcing ribs and the connecting rod are connected by a ball joint, so that the included angle of the X-shaped buffer reinforcing ribs changes within a range of 60°-120° when under pressure.
[0012] Preferably, the long elastic pads are arranged at equal intervals on the outer surface of the buffer layer, and the length direction of each long elastic pad is the same as the axial direction of the buffer layer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. In this utility model, a dual protection system is formed by the inner and outer anti-corrosion layers. This dual protection significantly improves the overall corrosion resistance of the pipeline and extends its service life.

This makes pipe installation, maintenance, or position adjustment more labor-saving and convenient. Simultaneously, the fit between screw holes one and two and the bolts fixes the position of the slide rail ring when the pipe does not need to move. The positioning rod further ensures accurate positioning, preventing the pipe from sliding in a stationary state and guaranteeing stability after installation. This design significantly reduces labor intensity during installation and maintenance, and improves work efficiency. Attached Figure Description

[0026] Please see Figure 1-5 This utility model provides a technical solution:
[0027] A novel steam pipe assembly includes an inner pipe 1. An inner anti-corrosion layer 2 is fixedly connected to the outer surface of the inner pipe 1. An insulation cotton layer 3 is fixedly connected to the outer surface of the inner anti-corrosion layer 2. A heat insulation layer 4 is fixedly connected to the outer surface of the heat insulation layer 3. A flame retardant layer 5 is fixedly connected to the outer surface of the heat insulation layer 4. A buffer assembly 6 is fixedly connected to the outer surface of the flame retardant layer 5. An outer anti-corrosion layer 7 is fixedly connected to the outer surface of the buffer assembly 6. Two rolling assemblies 8 are fixedly connected to the outer surface of the outer anti-corrosion layer 7. The inner pipe 1, the inner anti-corrosion layer 2, the insulation cotton layer 3, the heat insulation layer 4, the flame retardant layer 5, the buffer assembly 6, and the outer anti-corrosion layer 7 are arranged coaxially and the layers are tightly fitted together. The two rolling assemblies 8 are symmetrically distributed on both sides of the outer surface of the outer anti-corrosion layer 7.
[0028] Through the above scheme: the inner pipe 1 is made of high-temperature resistant seamless steel pipe, serving as the core channel for steam transportation and ensuring stable steam flow. The inner anti-corrosion layer 2 on the outer surface of the inner pipe 1 is made of epoxy resin coating, which can effectively resist the erosion of the inner pipe 1 by steam and corrosive media that may be generated inside the pipe, extending the service life of the inner pipe. The insulation cotton layer 3 outside the inner anti-corrosion layer 2 is made of aluminum silicate insulation cotton, which, through its excellent heat insulation performance, significantly reduces heat loss of steam during transportation and maintains the stability of steam temperature and pressure. The heat insulation layer 4 outside the heat insulation cotton layer 3 is made of aerogel felt, which further enhances the heat insulation effect of the pipe and reduces the impact of the external environment on the internal temperature of the pipe. The flame retardant layer 5 outside the heat insulation layer 4 is made of flame retardant polyvinyl chloride material, which can effectively prevent the spread of fire when exposed to open flames or high temperatures, providing safety protection for the pipe. The buffer component 6 outside the flame retardant layer 5 is made of rubber buffer layer 64 combined with X-shaped buffer reinforcing ribs made of elastic metal. 61, when the pipeline is subjected to external impact or vibration, the X-shaped buffer reinforcement ribs 61 and the elastic deformation of the buffer layer 64 absorb the impact force, protecting the internal structure of the pipeline from damage. The outer anti-corrosion layer 7 outside the buffer component 6 is made of polytetrafluoroethylene coating, which can resist the corrosion of the pipeline outer layer by rainwater, moisture, corrosive gases, etc. in the external environment, and improve the overall weather resistance of the pipeline. The rolling components 8 symmetrically distributed on both sides of the outer surface of the outer anti-corrosion layer 7 have high-strength alloy material for their outer connecting frame 81 and wear-resistant cast iron for the rolling wheel 86, which facilitates flexible sliding of the pipeline during installation, maintenance or movement, reducing the difficulty of operation and labor intensity. The coaxial setting and tight fit of the inner pipe 1, inner anti-corrosion layer 2, insulation cotton layer 3, heat insulation layer 4, flame retardant layer 5, buffer component 6 and outer anti-corrosion layer 7 ensure the stability and integrity of the pipeline structure and reduce energy loss or structural loosening caused by gaps between layers.
[0029] In this embodiment, the buffer assembly 6 includes a buffer layer 64. Multiple long elastic pads 63 are fixedly connected to the outer surface of the buffer layer 64. Multiple X-shaped buffer reinforcing ribs 61 are fixedly connected to the inner wall of the buffer layer 64. A connecting rod 62 is movably connected to the joint of the X-shaped buffer reinforcing ribs 61. The buffer layer 64 is fixedly connected to the inner surface of the outer anti-corrosion layer 7. The multiple X-shaped buffer reinforcing ribs 61 are evenly distributed on the inner wall of the buffer layer 64. The included angle between two adjacent X-shaped buffer reinforcing ribs 61 is equal. The intersection of the X-shaped buffer reinforcing ribs 61 is connected to the connecting rod 62 via a ball joint, so that the included angle of the X-shaped buffer reinforcing ribs 61 changes from 60° to 120° when under pressure. The long elastic pads 63 are arranged at equal intervals on the outer surface of the buffer layer 64, and the length direction of each long elastic pad 63 is the same as the axial direction of the buffer layer 64. The angle formed by the joint of the connecting rod 62 and the X-shaped buffer reinforcing rib 61 can change with the change of buffering force. The initial angle of the X-shaped buffer reinforcing rib 61 is 90°.
[0030] Through the above scheme: In the buffer assembly 6, the buffer layer 64 is fixedly connected to the inner surface of the outer anti-corrosion layer 7 as the basic structure. Multiple X-shaped buffer reinforcing ribs 61 are evenly distributed on its inner wall and have equal adjacent included angles. The angle is 90° in the initial state. When the pipeline is subjected to external pressure or impact, the structure in which the intersection of the X-shaped buffer reinforcing ribs 61 and the connecting rod 62 are connected by a ball joint plays a role. This allows the included angle of the X-shaped buffer reinforcing ribs 61 to change with the buffering force within the range of 60°-120°. Thus, it absorbs and disperses the impact force through its own deformation. At the same time, multiple long elastic pads 63 are evenly arranged on the outer surface of the buffer layer 64 and the length direction is the same as the axis direction of the buffer layer 64, which further enhances the buffering effect. It can effectively buffer the impact, vibration and other forces from the outside, avoid damage to the internal structure of the pipeline due to external forces, and protect the stability of steam transportation in the pipeline.
[0031] In this embodiment, the rolling assembly 8 includes an outer connecting frame 81. A slide rail groove 82 is formed in the middle of the inner surface of the outer connecting frame 81. A screw hole 83 is formed in the upper part of the outer surface of the outer connecting frame 81. A bolt 84 is threaded into the screw hole 83. A slide rail ring 85 is slidably connected in the slide rail groove 82. A plurality of rolling wheels 86 are rotatably connected to the outer surface of the slide rail ring 85. A positioning rod 87 is fixedly connected to the upper front end of the slide rail ring 85. A screw hole 88 is formed in the upper part of the outer surface of the slide rail ring 85. The outer connecting frame 81 is located outside the outer anti-corrosion layer 7. The rolling wheels 86 are distributed equidistantly in a ring around the slide rail ring 85. The screw hole 88 is located directly below the screw hole 83. The positional dimensions of the screw hole 88 and the screw hole 83 are adapted to the positional dimensions of the bolt 84. The outer connecting frame 81 has a circular ring structure.
[0032] Through the above scheme: the outer connecting frame 81, which has a circular structure in the rolling assembly 8, is located outside the outer anti-corrosion layer 7. The slide rail groove 82 in the middle of its inner surface provides a sliding track for the slide rail ring 85. Multiple rolling wheels 86, which are equidistantly distributed in a ring around the outer surface of the slide rail ring 85, can rotate flexibly. When it is necessary to move or adjust the position of the pipeline, the rolling wheels 86 can convert the sliding friction between the pipeline and the mounting surface into rolling friction, which greatly reduces the moving resistance and facilitates the installation, maintenance and position adjustment of the pipeline. The screw hole 83 on the upper part of the outer surface of the outer connecting frame 81 and the slide rail ring 85 are connected to the slide rail ring 85. The upper part of the outer surface has a screw hole 88 located directly below it. The position and size of the two holes are adapted to the bolt 84. The bolt 84 passes through the screw hole 83 and the screw hole 88 for threaded connection, which can fix the position of the slide rail ring 85 in the slide rail groove 82. The positioning rod 87 at the upper front end of the slide rail ring 85 can further ensure accurate positioning, prevent the pipeline from sliding in the non-moving state, and ensure the stability of the pipeline after installation. The design of this rolling component 8 not only realizes the convenient movement of the pipeline, but also reliably fixes its position, reduces the labor intensity of installation and maintenance, and improves construction efficiency.
[0033] It should be noted that this utility model is a novel steam pipe assembly. In this novel steam pipe assembly, steam flows in the inner pipe 1. The inner anti-corrosion layer 2 on the outer surface of the inner pipe 1 can prevent the inner pipe 1 from being corroded by steam. The insulation cotton layer 3 can reduce the loss of steam heat and play a heat preservation role. The heat insulation layer 4 further prevents heat from being transferred to the outside and reduces heat loss. The flame retardant layer 5 can prevent the fire on the outside of the pipe from causing greater impact on the inside of the pipe in special circumstances such as fire. When the pipe is subjected to external impact, the buffer assembly 6 plays a role. Multiple X-shaped buffer reinforcing ribs 61 are evenly distributed on the inner wall of the buffer layer 64. Their intersection points are connected to the connecting rod 62 by ball joints. The initial angle is 90°, and the included angle is 60°-120° when under pressure. Within the range of variation, it can effectively buffer impact force. Multiple long elastic pads 63 are arranged at equal intervals on the outer surface of the buffer layer 64 and their length direction is the same as the axial direction of the buffer layer 64, which further enhances the buffering effect. The outer anti-corrosion layer 7 protects the pipeline from external environmental corrosion. The rolling components 8 are symmetrically distributed on both sides of the outer surface of the outer anti-corrosion layer 7. When the pipeline is installed or moved, the slide rail ring 85 in the middle of the slide rail groove 82 on the inner surface of the outer connecting frame 81 can slide. Multiple rolling wheels 86 connected to the outer surface of the slide rail ring 85 are equidistantly distributed in a ring with the slide rail ring 85 as the center, which can reduce friction and facilitate pipeline maintenance. By adjusting the bolt 84 and the screw hole 1 83 and screw hole 2 88, the position of the rolling components 8 can be adjusted to achieve better control of pipeline movement.
