The ordinary FBE internal coating can be used for internal corrosion protection of pipelines transporting gas, water, light oil, and other media. The internal coating specially designed for drill pipes features high adhesion, high hardness, resistance to high temperatures and high pressures, and excellent resistance to hydrogen sulfide and carbon dioxide corrosion. The internal coating specially designed for oil tubing features high adhesion, resistance to high temperatures and high pressures, and excellent resistance to hydrogen sulfide and carbon dioxide corrosion.

The epoxy phenolic resin + special internal coating is generally used for transporting highly corrosive media, such as caustic soda, and offers excellent resistance to high temperatures and severe chemical corrosion.
