An anti-corrosion lining refers to a functional, corrosion-resistant protective layer applied to the inner surfaces of equipment—such as storage tanks, pipelines, reaction vessels, and chimneys. Its primary function is to **isolate the metal substrate from corrosive media**, thereby extending equipment service life, ensuring the purity of the contained media, and reducing maintenance costs. Offering a combination of properties—including corrosion resistance, wear resistance, and impact resistance—it is one of the most widely used and cost-effective technologies in modern industrial anti-corrosion systems.
