This TPEP steel pipe FBE/3LPE anti-corrosion coating line is a fully automatic, integrated coating system specifically designed for factory anti-corrosion treatment of large-diameter steel pipes. It supports multi-layer coating processes, including FBE single layer, 2LPE, 2LPP, and 3LPE, making it widely applicable in oil and gas pipelines, oilfield engineering, central heating systems, municipal water supply, and buried pipeline construction projects.
This complete 3LPE coating line integrates internal and external shot blasting derusting, intermediate frequency induction heating, electrostatic FBE powder spraying, hot-melt adhesive extrusion, outer PE cladding, water spray cooling, pipe end beveling, and a full PLC automatic control system. It achieves onetime simultaneous forming of the internal FBE epoxy layer, the middle adhesive layer, and the external 3LPE polyethylene protective layer, meeting international anti-corrosion standards and offering an ideal solution for long-distance buried steel pipe protection.
Premium Anti-Corrosion Performance - Professional internal and external FBE coating protects steel pipes against chemical erosion, aging, and mechanical damage, making them suitable for longterm operation in harsh oilfield, underground, and coastal environments.
Low Friction Pipeline Performance - The smooth coating surface reduces fluid transmission resistance, improves conveying efficiency, and cuts longterm energy costs for oil, gas, and water supply pipeline systems.
Wide Industry Application - The preferred 3LPE anticorrosion solution for oil and gas transmission, urban gas supply, municipal water and drainage, heating networks, and largescale infrastructure buried pipe projects.
High Automation & Cost Saving - The fully automatic operation reduces labor input; stable operation lowers failure rates, making this line a costeffective pipe coating machinery choice for manufacturers.
