[0002] Metal pipe fittings are engineering components commonly used in the chemical, petroleum, food, and pharmaceutical industries for the transmission of fluid media. At present, the long-term anti-corrosion treatment method for the atmospheric environment medium on the surface of metal pipes at home and abroad usually adopts the surface treatment of metal materials, such as paint spraying, plastic spraying, zinc spraying, aluminum spraying, aluminum-magnesium alloy spraying, zinc-aluminum alloy spraying, etc. These methods cannot achieve long-term anti-corrosion protection. In recent years, metal surface anti-corrosion treatment technology has attracted attention at home and abroad, and domestic development has adopted hot-dip galvanizing, hot-dip aluminum and hot-dip aluminum coating technologies.

The lower end of the high-temperature oil removal layer 107 is fixedly provided with a vacuum layer 10 8. A second high-quality carbon steel 109 is fixedly provided on the inner side of the first high-quality carbon steel 104.
