Description

Technical Field

[0001] This utility model belongs to the field of fluid transportation technology, and in particular relates to a wear-resistant and corrosion-resistant composite stainless steel pipe for fluid transportation pipelines. Background Technology

[0002] Fluid transport pipelines play a vital role in numerous fields such as industrial production, chemical processing, and oil and gas transportation, serving as indispensable infrastructure. These pipelines must not only withstand the continuous pressure exerted by fluids but also effectively resist corrosion and abrasion to ensure the safe and efficient transport of fluids.

[0003] Currently, most fluid transport pipelines on the market are made of stainless steel, a single material. Due to its good corrosion resistance and certain mechanical strength, stainless steel pipes meet the basic requirements for fluid transport to a certain extent. However, with the continuous development of industrial technology and the increasing complexity of application environments, the limitations of existing stainless steel pipes are gradually becoming apparent.

[0004] First, once installed, the position of existing stainless steel pipes is relatively fixed, making it difficult to adjust them according to changes in external equipment. When the pipes obstruct external equipment, they often need to be removed or rebuilt, increasing project costs and construction difficulty. Second, when handling high-pressure fluids, existing pipes often lack effective pressure relief mechanisms. When the fluid pressure is too high, the pipes may rupture or leak due to the inability to withstand the pressure, posing safety hazards to personnel and equipment. In addition, the wear and corrosion resistance of the lining materials of existing pipes is limited.

[0005] Therefore, it is essential to invent a wear-resistant and corrosion-resistant composite stainless steel pipe for fluid transportation pipelines. Utility Model Content

[0006] The purpose of this invention is to provide a wear-resistant and corrosion-resistant composite stainless steel pipe for fluid transportation pipelines, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a wear-resistant and corrosion-resistant composite stainless steel pipe for fluid transportation pipelines, comprising a relief pipe, an inlet pipe, a drain pipe, valves, a first bend, a connector, a second bend, a pressure relief mechanism, and an inner lining. Both ends of the relief pipe are fixed to the inlet or drain pipe via flanges, and valves are fixed to both ends of the relief pipe, the inlet pipe, and the drain pipe. A first bend is fixed to the outer surface of both ends of the relief pipe, with the other end of each first bend rotatably connected to the connector via a sealed bearing. A second bend is fixed to the other end of each connector, with the other end of each second bend fixed to either the inlet or drain pipe. A pressure relief mechanism is fixed to the outer surface of the relief pipe. An inner lining is compositely fixed to the inner walls of the relief pipe, inlet pipe, drain pipe, first bend, and second bend.

[0009] Furthermore, the pressure relief mechanism includes a pressure relief pipe, a pressure relief valve, and a temporary storage box. One end of the pressure relief pipe is connected to the bypass pipe, and the other end of the pressure relief pipe is connected to the temporary storage box through the pressure relief valve. This arrangement can prevent excessive fluid pressure from causing damage to the pipeline.

[0010] Furthermore, the inner lining is made of ceramic material, and the inner wall of the lining has a corrugated structure. This design can improve the wear resistance and corrosion resistance of the pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention allows for the following: when the stainless steel pipe obstructs external equipment, the valve can be closed, and then the connection between the clearance pipe and the inlet and outlet pipes can be opened. Then, the first bend pipe can be rotated to move the position of the clearance pipe, and then fluid can be transported through the first bend pipe, the second bend pipe and the clearance pipe, thereby providing space for the external equipment.

[0013] The pressure relief mechanism of this invention is designed so that when the pressure of the flowing liquid is too high, the pressure can break through the restriction of the pressure relief valve, allowing the fluid to enter the storage tank, thereby preventing the fluid pressure from being too high and causing damage to the pipeline.

[0014] The lining of this invention provides wear and corrosion resistance from the ceramic material during use. Furthermore, the lining absorbs energy and reduces wear through the deformation and rebound of the inner wall corrugations. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 As shown, this utility model is a wear-resistant and corrosion-resistant composite stainless steel pipe for fluid transportation pipelines, including a relief pipe 1, an inlet pipe 2, a drain pipe 3, a valve 4, a first bend pipe 5, a connector 6, a second bend pipe 7, a pressure relief mechanism 8, and an inner liner 9. Both ends of the relief pipe 1 are fixed to the inlet pipe 2 or the drain pipe 3 respectively through flanges, and valves 4 are fixed to both ends of the relief pipe 1, the inlet pipe 2, and the drain pipe 3. The outer sides of both ends of the relief pipe 1 are fixed with first bend pipes 5, and the other end of the first bend pipe 5 is rotatably connected to the connector 6 through a sealed bearing. The other end of the connector 6 is fixed with a second bend pipe 7, and the other end of the second bend pipe 7 is fixed to the inlet pipe 2 or the drain pipe 3 respectively. The pressure relief mechanism 8 is fixed to the outer side of the relief pipe 1. The inner walls of the relief pipe 1, the inlet pipe 2, the drain pipe 3, the first bend pipe 5, and the second bend pipe 7 are all compositely fixed with an inner liner 9.

[0025] Specifically, the pressure relief mechanism 8 includes a pressure relief pipe 81, a pressure relief valve 82, and a temporary storage tank 83. One end of the pressure relief pipe 81 is connected to the bypass pipe 1, and the other end of the pressure relief pipe 81 is connected to the temporary storage tank 83 through the pressure relief valve 82. When the pressure of the flowing liquid is too high, the pressure can break through the restriction of the pressure relief valve 82, allowing the fluid to enter the interior of the temporary storage tank 83, thereby preventing the fluid pressure from being too high and causing damage to the pipeline.

[0026] Specifically, the inner liner 9 is a tube made of ceramic material, and the inner wall of the inner liner 9 has a corrugated structure. When in use, the ceramic material has wear-resistant and corrosion-resistant properties, and the inner liner 9 can absorb energy and reduce wear through the deformation and rebound of the inner wall corrugations.

Its working principle is as follows: When in use, fluid can be transported through the inlet pipe 2, the bypass pipe 1, and the drain pipe 3. When the stainless steel pipe obstructs external equipment, the valve 4 can be closed, and then the connection between the bypass pipe 1 and the inlet pipe 2 and the drain pipe 3 can be opened. Then, the first bend pipe 5 is rotated to move the position of the bypass pipe 1. Then, the fluid is transported through the first bend pipe 5, the second bend pipe 7, and the bypass pipe 1, thereby providing space for external equipment. In addition, the pressure relief mechanism 8 can prevent the fluid pressure from being too high, which could lead to pipeline damage.
