Description

Technical Field

[0001] This utility model relates to the field of pipeline joint technology, specifically a ground pipeline anti-corrosion protection joint. Background Technology

[0002] In many fields such as industrial production, energy transmission, and municipal infrastructure construction, surface pipelines are key facilities for transporting various media (such as oil, natural gas, water, and chemical raw materials) and are widely distributed in various complex environmental conditions. However, due to long-term exposure to corrosive factors such as the atmosphere, soil, and various chemicals, the connection between two adjacent surface pipelines faces serious corrosion problems. This not only shortens the service life of the pipeline but may also lead to media leakage. Therefore, it is necessary to design anti-corrosion protection for the protective joints connecting pipelines.

[0003] Traditional ground pipeline connections typically employ simple welding or threaded connections, followed by general anti-corrosion measures such as applying anti-corrosion paint to the joints. However, during actual installation and use, ordinary anti-corrosion paint coatings are easily affected by factors such as ultraviolet radiation, temperature changes, mechanical scratches, and chemical corrosion during long-term outdoor use, resulting in aging, cracking, and peeling. Consequently, they lose their anti-corrosion performance and cannot provide durable and effective protection for the joints. Furthermore, common joints have relatively poor tolerance and pressure resistance, limiting their applicability. Therefore, we propose a ground pipeline anti-corrosion protection joint to address these issues. Utility Model Content
