Description

Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to a high-strength galvanized stainless steel seamless steel pipe. Background Technique

[0002] Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, and as pipes for oil heaters, condensers, and coal distillation wash oil exchangers in chemical coking equipment.

[0003] Most of the existing seamless steel pipes are connected and sealed through flange plates. When these steel pipes are installed and transporting some liquids, the staff will check them at regular intervals to prevent the joints from being affected by vibration and internal pressure shocks, resulting in leakage at the flange joints. When the leakage gap is small, it may be difficult for inspectors to detect. To solve this technical problem, the utility model proposes a high-strength galvanized stainless steel seamless steel pipe. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a high-strength galvanized stainless steel seamless steel pipe, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A high-strength galvanized stainless steel seamless steel pipe includes an inner pipe. A flange plate is connected to the outer surface of the inner pipe. A water storage tank is opened inside the flange plate. A collecting plate is slidably connected to the inner side wall of the water storage tank. A sealing sleeve is installed inside the collecting plate. A transfer pipe is installed inside the sealing sleeve. A limiting shell is slidably connected to the upper surface of the flange plate. A connecting block is connected inside the limiting shell. A supporting ring is connected inside the connecting block. A color-changing sleeve is installed on the outer surface of the supporting ring. A transparent plate is installed inside the limiting shell. A heat preservation mechanism is arranged on the outer surface of the inner pipe. A water hammer eliminator is installed inside the inner pipe.

[0007] Preferably, the heat preservation mechanism includes a connecting ring. The outer surface of the connecting ring is connected to the outer surface of the inner pipe. A heat insulation pipe is connected to the outer surface of the connecting ring.

[0008] Preferably, a vacuum layer is opened between the heat insulation pipe and the inner pipe. The water hammer eliminator is installed inside the heat insulation pipe. The inside of the heat insulation pipe is connected to the outer surface of the flange plate.

[0009] Preferably, a fixing bolt assembly is installed inside the flange plate. The outer surface of the sealing sleeve is in contact with the inside of the flange plate.

[0010] Preferably, one end of the transfer pipe is in contact with the outer surface of the color-changing sleeve, and the outer surface of the sealing sleeve is in contact with the outer surface of the color-changing sleeve.

[0011] Preferably, the outer surface of the connecting block is in contact with the outer surface of the color-changing sleeve, and the outer surface of the transparent plate is in contact with the outer surface of the color-changing sleeve.

[0012] Preferably, the sealing sleeve is installed inside the limit shell, and the outer surface of the connecting block is connected to the inside of the transparent plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, through the cooperation between components such as the transfer pipe and the color-changing sleeve, firstly, the transfer pipe can transport the leaked material to a suitable position. When the material transported in the inner pipe leaks, the leaked material will enter the transfer pipe under the action of the collecting plate and be transported to a suitable place by the transfer pipe. The color-changing sleeve can change color when it comes into contact with the leaked material. After the transfer pipe transports the leaked material to the position in contact with the color-changing sleeve, the color-changing sleeve will change color, and the transparent plate allows the inspector to observe the internal situation. When the color-changing sleeve changes color, the inspector can directly observe it, thus facilitating the detection of the inspector and solving the problem that it is difficult for the inspector to detect due to small gaps.

[0015] In the utility model, through the cooperation between components such as the connecting block and the heat preservation mechanism, the connecting block can divide the color-changing sleeve into pieces, so that when the liquid in the inner pipe leaks, the color-changing sleeves will not infect each other, thus facilitating the inspector to know the infiltration speed of the liquid. The heat preservation mechanism can reduce the heat loss of the material transported in the inner pipe, so that the material transported in the inner pipe will not have its temperature change rapidly due to too large a temperature difference with the outside world, which is very practical.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a high-strength galvanized stainless steel seamless steel pipe includes an inner pipe 1. A flange 2 is connected to the outer surface of the inner pipe 1. A water storage tank 3 is provided inside the flange 2. The inner pipe 1 fixes the position of the flange 2, and the water storage tank 3 is used to carry a part of the material flowing out from the flange 2.

[0024] A collection plate 4 is slidably connected to the inner side wall of the water storage tank 3. A sealing sleeve 5 is installed inside the collection plate 4. The collection plate 4 carries these flowing materials, and the collection plate 4 restricts the position of the sealing sleeve 5 to prevent the liquid material from flowing out from the sealing sleeve 5.

[0025] A transfer pipe 6 is installed inside the sealing sleeve 5. A limit shell 7 is slidably connected to the upper surface of the flange 2. The sealing sleeve 5 can prevent the liquid from flowing out at the position where the sealing sleeve 5 contacts the transfer pipe 6, so that the liquid accumulated in the collection plate 4 can flow out through the transfer pipe 6. The flange 2 can be placed inside the limit shell 7, and the position of the limit shell 7 is restricted by the two flanges 2.

[0026] A connecting block 8 is connected inside the limit shell 7, and a support ring 9 is connected inside the connecting block 8. The limit shell 7 fixes the position of the connecting block 8 to prevent the connecting block 8 from moving, and the connecting block 8 fixes the position of the support ring 9 to allow the support ring 9 to move.

[0027] A color-changing sleeve 10 is installed on the outer surface of the support ring 9, and a transparent plate 11 is installed inside the limit shell 7. The support ring 9 fixes the position of the color-changing sleeve 10. According to the different liquids to be transported, corresponding color-changing sleeves 10 need to be installed. These color-changing sleeves 10 can change color when they come into contact with the liquid flowing out of the inner pipe 1, so that the inspection personnel can discover abnormalities. The limit shell 7 holds the transparent plate 11, allowing the inspection personnel to observe the color change of the color-changing sleeve 10 through the transparent plate 11. Holes are provided on the surface of the transparent plate 11, and these holes allow the liquid to flow out.

[0028] The outer surface of the inner pipe 1 is provided with a heat preservation mechanism 12. A water hammer eliminator 13 is installed inside the inner pipe 1. The inner pipe 1 fixes the position of the water hammer eliminator 13. The water hammer eliminator 13 can effectively eliminate the irregular water hammer oscillations of various fluids generated in the transmission system, such as external water hammers and surges, without preventing the fluid from flowing, thereby eliminating the destructive shock waves and achieving the purpose of protection.

[0029] The heat preservation mechanism 12 includes a connecting ring 1201. The outer surface of the connecting ring 1201 is connected to the outer surface of the inner pipe 1. The outer surface of the connecting ring 1201 is connected with a heat insulation pipe 1202. The inner pipe 1 fixes the position of the connecting ring 1201. The connecting ring 1201 has a certain heat preservation ability. The connecting ring 1201 fixes the position of the heat insulation pipe 1202. The heat insulation pipe 1202 and the inner pipe 1 are connected through the connecting ring 1201. The heat insulation pipe 1202 also has a certain heat preservation ability.

[0030] A vacuum layer 1203 is provided between the heat insulation pipe 1202 and the inner pipe 1. The water hammer eliminator 13 is installed inside the heat insulation pipe 1202. The inner part of the heat insulation pipe 1202 is connected to the outer surface of the flange 2.

[0031] Fixing bolt assemblies 14 are installed inside the flange 2. The outer surface of the sealing sleeve 5 is in contact with the inside of the flange 2. The two flanges 2 are connected through the fixing bolt assemblies 14 to complete the connection of the steel pipes. The two flanges 2 clamp the sealing sleeve 5 to prevent liquid from flowing through this place.

[0032] One end of the transfer pipe 6 is in contact with the outer surface of the color-changing sleeve 10. The outer surface of the sealing sleeve 5 is in contact with the outer surface of the color-changing sleeve 10. By directly contacting the transfer pipe 6 with the color-changing sleeve 10, the liquid transported by the transfer pipe 6 enters the color-changing sleeve 10. The sealing sleeve 5 can prevent the liquid inside the color-changing sleeve 10 from flowing through the sealing sleeve 5.

[0033] The outer surface of the connecting block 8 is in contact with the outer surface of the color-changing sleeve 10. The outer surface of the transparent plate 11 is in contact with the outer surface of the color-changing sleeve 10. The connecting block 8 restricts the position of the color-changing sleeve 10, preventing the color-changing sleeve 10 from moving randomly and also preventing the liquid inside the color-changing sleeve 10 from infecting other color-changing sleeves 10. Thus, the user can identify the liquid loss rate through the color change of the color-changing sleeve 10. The transparent plate 11 restricts the position of the color-changing sleeve 10.

[0034] The sealing sleeve 5 is installed inside the limit shell 7. The outer surface of the connecting block 8 is connected to the inside of the transparent plate 11. The transfer pipe 6 inside the sealing sleeve 5 will limit the position of the limit shell 7, preventing the limit shell 7 from moving horizontally, and the connecting block 8 will fix the position of the transparent plate 11.
