Corrosion-resistant coating for steel-lined pipes is selected from domestic modified epoxy powder coating, which features strong adhesion, smooth surface, corrosion resistance, and non-scaling. Pipe connections are made with special connectors, which are made from special heat-resistant insulating materials and processed through special techniques. During on-site welding, heat is not directly transferred to the coating on the internal surface of the joint, ensuring that the welding joint maintains an intact and undamaged corrosion-resistant layer, achieving overall corrosion protection for the entire pipeline.
