Steel Pipe Internal External FBE Powder Coating & Liquid Paint Spraying Line
Product Description
This high-efficiency production line integrates automated shot blasting rust removal, electrostatic Fusion Bonded Epoxy (FBE) powder coating, and heavy-duty liquid paint spraying into a unified system. Engineered for both the inner and outer walls of large-diameter steel pipes, this dual-application plant is the premier anti-corrosion solution for high-stakes pipeline infrastructure.
The treated pipes feature a uniform, dense, and continuous barrier with exceptional chemical resistance against acids, alkalis, and salts. Its smooth internal finish reduces hydraulic frictional drag, significantly optimizing long-distance fluid transmission efficiency. This system is widely specified for manufacturing oil and gas transmission pipelines, municipal water networks, and industrial chemical fluid lines.
Internal & External FBE Powder Coating
Epoxy powder is a thermosetting, non-toxic coating. After curing, it forms a high-molecular cross-linked structure coating, which has excellent chemical anti-corrosion performance and mechanical strength. Its base layer is bonded and cured on the surface of the steel pipe to form a continuous coating, providing excellent adhesion, chemical corrosion resistance, and cathodic disbondment resistance. Polymer adhesives bond epoxy powder before gelation and connect the top layer of polyethylene, making the three-layer structure closely combined into one.
Multi-Layer Liquid Paint Spraying & 3LPE Integration
Beyond dry powder application, this machinery features an integrated liquid industrial paint spraying system. This enables the production line to effortlessly handle liquid epoxy coatings, specialized liquid anti-corrosion paints, and the critical adhesive-to-polyethylene interlayers required for standard 3LPE (Three-Layer Polyethylene) pipe production.
