Applications

The external coating is mainly used for anti-corrosion protection for liquid pipes before burying, and internal drag-reducing coating is mainly used to reduce the investment and maintenance costs.

External Corrosion Protection for Steel Pipes

Single-layer FBE Coating, Two-layer FBE Coating(2FBE), Two-layer PE/PP Coating(2PE/2PP), Three-layer PE/PP Coating(3PE/3PP), Epoxy coal asphalt coatings, Polyurethane heat preservation etc.

Internal Corrosion Protection for Steel Pipes: Epoxy coating, cement mortar lining etc.
