Fusion-bonded epoxy (FBE) coated steel pipes are products that utilize PE (modified polyethylene) for hot-dip coating or EP (epoxy resin) for internal and external coating, boasting excellent corrosion resistance. The coating itself also offers good electrical insulation without causing electrolytic erosion. They have low water absorption, high mechanical strength, and a small friction coefficient, ensuring long-term use. They also effectively prevent damage from plant root systems and soil environmental stresses. They feature convenient connection and easy maintenance.
