[0002] The pipes of oil pipelines are generally steel pipes, which are connected into long-distance pipelines using welding and flanges, and valves are used for opening and closing control and flow regulation. Oil pipelines mainly have isothermal transportation, heating transportation and sequential transportation. Pipeline corrosion and how to prevent corrosion are one of the important links in pipeline maintenance.
[0003] However, in actual use, welding causes the delivery pipe to form a very long pipe. When the delivery pipe is damaged somewhere, the entire pipe needs to be replaced, and disassembly is also time-consuming and labor-intensive. When the existing installation style delivery pipe is in use, the installation part is buried in the soil, which will cause the installation part to be blocked by the soil, making it inconvenient to disassemble. In addition, the metal material will be corroded and rusted in the soil. If it is not protected, the installation parts will be connected together due to electrochemical reactions, which will be more difficult to dismantle. Utility Model Content
