Fusion-bonded epoxy (FBE) coated steel pipes are products that use PE (modified polyethylene) for hot-dip coating or EP (epoxy resin) for internal and external coating, offering excellent corrosion resistance. The coating itself also boasts good electrical insulation properties, preventing electrolytic corrosion. 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.
