Specialized Coatings for Seamless Pipes: Enhancing Corrosion and Wear Resistance

Surface coatings are crucial in protecting seamless pipes from corrosion, abrasion, and oxidation in extreme environments.

Types of Seamless Pipe Coatings

FBE (Fusion-Bonded Epoxy):

• Benefits: High resistance to abrasion, impact, and chemicals.
• Applications: Underground pipelines, subsea oil transport.

3LPE (Three-Layer Polyethylene):

• Structure:

Epoxy primer → Adhesive → Polyethylene outer layer.

• Benefits: Ideal for moisture and mechanical protection.
• Applications: Buried natural gas pipelines.

Ceramic Coatings:

• Effect: High erosion and thermal resistance, suitable for extreme temperatures.
• Applications: Supercritical steam pipelines in power plants.

Nickel & Chromium Cladding:

• Effect: Improves pitting corrosion resistance, extending service life in harsh chemical processing environments.
• Applications: Desalination plants, offshore oil rigs.
