Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion pipeline technology, specifically to a carbon steel anti-corrosion pipeline with an enamel lining. Background Technology

[0002] Anti-corrosion steel pipes refer to steel pipes that have undergone anti-corrosion processing to effectively prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use. According to statistics in my country, the direct economic loss from steel pipe corrosion in the country exceeds 280 billion yuan annually, while the global annual loss due to steel pipe corrosion is as high as 500 billion US dollars. Anti-corrosion steel pipes can effectively prevent or slow down corrosion, extend the service life of steel pipes, and reduce operating costs. An existing patent, patent publication number CN107816600A, discloses an anti-corrosion pipe with the following preparation method: 60-90 parts of polyurethane, 20-30 parts of toluene diisocyanate, and 15-20 parts of trihydroxy polyether are mixed and stirred for 20-40 minutes; then 11-15 parts of quartz powder and 4-6 parts of zinc phosphate are added and mixed for 15-20 minutes. After mixing, the mixture is heated for 20 minutes to 60 degrees Celsius; after heating, 3-6 parts of talc powder, 5-10 parts of barium sulfate, 1-2 parts of castor oil, and 2-3 parts of zinc powder are added, and the mixture is stirred while maintaining a temperature of 50 degrees Celsius for 30 minutes. The improved formula of this invention has strong anti-corrosion properties. The coating prepared using this process can maintain its anti-corrosion effect for up to ten years when applied to the outside of pipes.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: in practical applications, it is inconvenient to connect pipes, and it is also impossible to increase the sealing between pipes, which reduces the ease of use of the pipes and affects the normal use of subsequent pipes. Therefore, we propose a carbon steel anti-corrosion pipe with an enamel lining to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a carbon steel anti-corrosion pipe with an enamel lining, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon steel anti-corrosion pipe with an enamel lining, comprising a horizontal pipe, one end of which is connected to a connecting pipe. An annular groove is formed on one side of the connecting pipe, and a return spring is fixedly installed on one side of the inner wall of the annular groove. A sealing ring is fixedly installed on one end of the return spring, and a groove is formed on one side of the sealing ring. During use, the return spring resets the sealing ring, causing one end of the sealing ring to contact one end of the horizontal pipe. This facilitates installation and positioning during use, thereby improving the connection convenience of the pipe and simplifying subsequent use.

[0006] A positioning ring is fixedly installed on the surface of the horizontal pipe. A limit plate is fixedly installed on one side of the positioning ring, and a screw is fixedly installed on one side of the limit plate. A limit ring is inserted into the screw. An annular sealing groove is opened at one end of the horizontal pipe. A nut is threadedly connected to the surface of the screw. The screw and nut facilitate the positioning between the two pipes during use, thereby facilitating subsequent adjustment and positioning operations. This improves the ease of use of the pipe, facilitates subsequent operations, and increases the efficiency of the pipe's use.

[0007] Preferably, the surface and inner wall of the sealing ring are slidably connected to the inner wall of the annular groove, and the annular groove is adapted to the sealing ring. The adaptation of the annular groove to the sealing ring increases the sealing performance between the components during use, facilitates subsequent use, and also facilitates the connection operation of the staff.

[0008] Preferably, a mounting plate is fixedly installed on one side of the connecting pipe. The mounting plate has an oblong mounting hole, and one side of the mounting plate has anti-slip texture. The mounting plate facilitates the installation and positioning of the pipe during use, thereby facilitating subsequent positioning and connection and preventing the pipe from shaking during use, thus improving the ease of use of the component.

[0009] Preferably, the limiting ring has a threaded hole for the screw to pass through. The threaded hole is threaded to the screw, and the inner wall of the threaded hole is slidably connected to the surface of the screw. The threaded hole facilitates the passage of the screw during use and also facilitates the subsequent positioning operation of the screw, thereby improving the connection operation of the pipeline.

[0010] Preferably, a silicone ring is fitted on the surface of the screw, the inner wall of the silicone ring is slidably connected to the surface of the screw, and the silicone ring is adapted to the screw. The silicone ring facilitates the connection between components during use, thereby increasing the sealing between components.

[0011] Preferably, one side of the silicone ring is fitted with one side of the limiting ring, and the other side of the silicone ring is fitted with one side of the nut.

[0012] Preferably, the horizontal pipe is provided with an inner liner, the surface of which is fixedly connected to the surface of the horizontal pipe. The inner liner prevents pipe corrosion during use, thereby improving the pipe's corrosion resistance. Beneficial effects

[0013] This utility model provides a carbon steel anti-corrosion pipe with an enamel lining. Compared with the prior art, it has the following advantages:

[0014] This carbon steel corrosion-resistant pipe with an enamel lining uses a connecting pipe and a return spring to reset the sealing ring during use, so that one end of the sealing ring contacts one end of the horizontal pipe. This facilitates installation and positioning during use, thereby improving the connection convenience of the pipe and making it easier for subsequent use.

[0015] Meanwhile, the screw and nut facilitate positioning between the two pipes during use, which in turn makes subsequent adjustment and positioning operations easier, thereby improving the ease of use and efficiency of the pipe. Attached Figure Description
