Anticorrosion method of petroleum casing
The anticorrosion of oil casing is mainly divided into:
1. Brush anti-corrosion coating on the outer wall.
2. Brush anti-corrosive coating on the inner wall.
3. Brush the anti-corrosion cooling coating.
With the use of oil casings in the harsh oil mining industry such as the polar regions and oceans, the materials and structures of oil casings must have good joints, excellent physical properties, stable chemical properties, and a wide temperature range . If the oil casing fails to meet these requirements, it should be coated with anti-corrosion coating to cope with the harsh environment. The anti-corrosive coating on the outer wall is used to reduce external erosion. The anti-corrosion coating on the inner wall is to reduce friction, reduce corrosion in the pipe, and increase oil transportation. The anti-corrosion and heat-insulating coating is used to transport crude oil and fuel oil and reduce the heat dissipation from the pipeline to the soil.
