Seamless Steel Pipe External Anti-Corrosion Coating

Purpose of External Anti-Corrosion

• Effectively prevents chemical and electrochemical corrosion

• Extends service life of seamless steel pipes

• Reduces maintenance and replacement costs

• Improves operational safety and reliability

• Suitable for buried, underwater, marine, and harsh environments

Available Anti-Corrosion Types

We can supply seamless steel pipes with various external anti-corrosion coatings according to project requirements:

• Epoxy Coating (FBE)
  Strong adhesion, excellent chemical resistance, ideal for buried pipelines

• Epoxy Coal Tar Coating
  Good water resistance and cost-effective solution for municipal and mining pipelines

• 3LPE / 3LPP Coating
  Three-layer structure: FBE + adhesive layer + PE or PP outer layer
  Excellent corrosion resistance, impact resistance, and mechanical strength
  Widely used for oil, gas, and long-distance transmission pipelines

• Polyurethane (PU) Coating
  High wear resistance, suitable for abrasive and high-impact conditions

• Galvanized Coating
  Cathodic protection for outdoor or atmospheric environments
