The Dual Powder System (DPS) pipeline coating is an advanced, two-layer fusion-bonded epoxy (FBE) solution. It combines a corrosion-resistant base layer with a tough, flexible outer layer. This design provides superior mechanical protection, abrasion resistance, and enhanced durability, making it ideal for challenging environments like directional drilling, rocky terrains, and offshore applications.
