Anti-corrosion process of steel casing pipe
Anti-corrosion measures and procedures are as follows: It is one of the basic methods for pipeline anticorrosion to evenly and densely coat the surface of the rust-removed metal pipeline with paint to isolate it from various corrosive media. 1. When coating the anti-corrosion layer of steel casing pipe, it is necessary to pay attention to the environmental factors such as temperature and humidity at the coating site, which directly affect the coating effect. When the steel casing pipe is coated with anti-corrosion coating indoors, the temperature should be controlled at 20-25 degrees Celsius, and the relative humidity varies depending on the material of the casing, generally about 65%. 2. When constructing outdoors, there should be no wind, sand and drizzle. The temperature should not be lower than 5 degrees Celsius, and the relative humidity should not be greater than 85%. The drying and curing temperatures of various anti-corrosion coatings used in steel casing pipe vary greatly...
