Traditional tee pipe is mostly made of carbon steel or other materials, but these materials are easy to oxidize, corrode or damage in high temperature or corrosive environment, causing leakage, blockage or rupture of pipeline system. Therefore, using stainless steel as the material of tee pipe can not only prolong the service life of pipeline, but also enhance the safety and reliability of the system.
[0004] However, the flow efficiency of the existing tee pipe is low, and the mixing effect of multiple fluids is poor. UTILITY MODEL CONTENTS

[0006] The utility model is realized as follows:
[0007] The utility model provides a stainless steel tee pipe, which comprises a first pipe segment, a second pipe segment and a third pipe segment, the first pipe segment and the second pipe segment are perpendicular to each other and are welded and connected, forming a T-shaped main body, the third pipe segment is welded and connected with the first pipe segment at an angle, forming a tee structure, the first pipe segment is cylindrical and serves as a main fluid passage, the second pipe segment and the third pipe segment are both cylindrical and serve as branch fluid passages, the connection between the first pipe segment and the second pipe segment and the third pipe segment is arc-shaped, and the third pipe segment is located near the intersection of the first pipe segment and the second pipe segment, which can enhance the structural strength and guide the fluid direction, and guide vanes are arranged on the inner wall of the first pipe segment, which can guide fluid flow and improve the mixing efficiency.
[0008] On the basis of the above technical solutions, the stainless steel tee pipe can be further improved as follows:
[0009] The overall outer wall formed by the first pipe section, the second pipe section and the third pipe section is provided with a heat preservation layer to reduce heat loss and maintain stable fluid temperature.
[0010] Further, the inner diameter of the first pipe section is greater than the inner diameters of the second pipe section and the third pipe section to ensure smooth flow of the main fluid.
[0011] Further, the inner diameters of the second pipe section and the third pipe section are the same to ensure uniform distribution of the branch fluid.
[0012] Further, the intersection of the first pipe section and the second pipe section is provided with a reinforcing rib to improve the structural strength and impact resistance of the tee pipe.
[0013] Further, the first pipe section, the second pipe section and the third pipe section are all made of 304 stainless steel.
[0014] Further, the angle between the third pipe section and the first pipe section is between 15-75° to ensure smooth fluid flow.
[0015] Further, the heat preservation layer adopts a multi-layer composite structure including a heat insulation layer, a reflective layer and a protective layer.
[0016] Further, the heat insulation layer adopts a low thermal conductivity material to reduce heat transfer; the reflective layer adopts a high reflectivity material to reflect heat radiation; and the protective layer adopts a corrosion-resistant and wear-resistant material to protect the heat preservation layer from the influence of the external environment.
[0017] Further, the side of the first pipe section, the second pipe section and the third pipe section not connected to each other is provided with a flange connector to facilitate connection with other pipelines or equipment.
[0018] Compared with the prior art, the stainless steel tee pipe has the following advantages:
[0019] The first pipe section is cylindrical and serves as the main channel for fluid. This part is the core channel of the tee pipe and is used for the flow of the main fluid. The inner wall of the first pipe section is provided with guide vanes, which change the flow direction of the fluid, promote mixing of the fluid and reduce turbulence, thereby improving mixing efficiency and uniformity of the fluid. The inner diameter of the first pipe section is greater than that of the second pipe section and the third pipe section, which ensures smooth flow of the main fluid and avoids increase of fluid resistance.
[0020] The second pipe segment is a cylindrical shape, which is used as a branch channel for the fluid. It is connected to the first pipe segment and is perpendicular to the first pipe segment, forming a T-shaped structure. The main function of the second pipe segment is to guide the fluid to flow in the branch direction. The connection between the second pipe segment and the first pipe segment is designed to be arc-shaped, which helps to reduce the impact force of the fluid and avoid the instability of the fluid caused by sharp turns, thereby improving the fluidity of the fluid.
[0021] The third pipe segment is also a cylindrical shape, which is used as another branch channel for the fluid. It is connected to the first pipe segment at an angle, forming a tee structure. The connection angle between the third pipe segment and the first pipe segment is in the range of 15° to 75°, which is designed to ensure the smooth flow of the fluid and reduce the resistance caused by the turning of the fluid. Too small an angle will increase the difficulty of fluid flow, and too large an angle will affect the stability of the fluid. The design of 15° to 75° can maintain the smooth flow of the fluid. The third pipe segment is arranged close to the intersection of the first pipe segment and the second pipe segment, which can enhance the strength of the entire structure, help to share the fluid pressure, and guide the correct flow direction of the fluid.
[0022] The connection between the first pipe segment and the second pipe segment, the third pipe segment is designed to be arc-shaped, which not only enhances the strength of the structure, but also makes the pressure change of the fluid smaller when turning, which can smoothly transition to the next pipe. The intersection of the first pipe segment and the second pipe segment is designed with a reinforcing rib, which can significantly improve the impact resistance of the tee pipe, enhance the durability and stability of the structure, and avoid damage to the structure caused by external impact or high-pressure fluid.
[0023] The outer wall is provided with a thermal insulation layer to reduce heat loss and ensure the stability of the fluid temperature. Especially when the fluid temperature is high or low, the thermal insulation layer can prevent heat loss or the influence of external heat sources, thereby maintaining the temperature of the fluid within the ideal range. The thermal insulation layer adopts a multi-layer composite structure, including a heat insulation layer, a reflective layer and a protective layer: the heat insulation layer uses low thermal conductivity material, which can effectively reduce the heat transfer. The reflective layer uses high reflectivity material, which can reflect the thermal radiation in the fluid, further reducing heat loss. The protective layer uses corrosion-resistant and wear-resistant materials to protect the thermal insulation layer from the external environment, prolonging its service life.
[0024] The three pipe segments are made of 304 stainless steel, which has good corrosion resistance, strength and high temperature resistance, and is suitable for long-term use in fluid transmission. 304 stainless steel can effectively deal with corrosive substances and pressure changes in the fluid.
[0025] Flange connectors are provided on any side of the tee pipe that is not connected to each other, which facilitates connection with other pipelines or equipment. This can facilitate the installation, disassembly and maintenance of the pipeline system. BRIEF DESCRIPTION OF DRAWINGS

[0041] Specifically, the principle of the utility model is: before installation, ensure that the tee pipe, connecting flange and other pipeline accessories are not damaged or defective. Check whether the pipeline has rust, cracks or deformation. According to the system design requirements, confirm the size, angle (15° to 75°) of the tee pipe and its adapted pipeline diameter, and ensure the compatibility with other pipelines. Before installing the tee pipe, all connecting surfaces must be cleaned to remove oil stains, dust and other impurities, and ensure good sealing. Connect the first pipe section of the tee pipe with the main flow pipeline. Ensure that the inflow direction of the first pipe section is consistent with the flow direction of the main fluid, to avoid fluid unsmoothness caused by wrong direction. Connect the second pipe section and the third pipe section with the corresponding branch pipelines respectively.

Before starting, confirm that the fluid inlet and outlet direction and the flow path of the pipeline system are correct. The fluid should flow in the expected path, to avoid reverse flow or unsmooth flow. Perform water test or air test to check whether there is leakage at all connections. After the inspection, gradually increase the pressure of the system to ensure that the strength of the pipeline system meets the requirements. If the pipeline system involves high temperature or low temperature fluid, the effect of the insulation layer should be checked regularly after starting, to ensure that the fluid temperature is maintained within the appropriate range. During the operation of the pipeline, monitor whether the fluid flow rate is stable, especially at the branch of the tee pipe, to ensure that the flow direction of the fluid is not disturbed or unstable. Ensure that the insulation layer of the tee pipe is working properly, especially in the pipeline system that needs to maintain temperature, the insulation layer can effectively prevent heat loss. Check the integrity and sealing performance of the pipeline regularly. Check whether the insulation layer is damaged or deformed, especially in harsh external environments, such as high temperature or corrosive gas areas.
