PLC Controlled FBE Coating Line for Internal & External Pipe Wall with SA2.5 Surface Preparation

The Huashida internal & external epoxy powder FBE coating line is a professional, fully automated turnkey corrosion protection solution exclusively engineered for steel pipe inner and outer wall anti-corrosion treatment. As a Shandong Provincial First-set Technical Equipment certified product, this industrial-grade FBE epoxy powder coating line adopts mature fusion-bonded epoxy technology, integrating high-precision shot blasting derusting, medium-frequency induction heating, electrostatic powder spraying, high-temperature curing, and water cooling shaping into one streamlined unmanned production system. Specialized in single-layer and double-layer internal and external FBE anti-corrosion processing, the equipment resolves core industry , including insufficient coating adhesion, uneven epoxy coverage, medium chemical corrosion, high manual operation error, and frequent equipment failure. Compatible with diversified steel pipe specifications ranging from 159mm to 4200mm, this steel pipe FBE anti-corrosion coating line is widely validated for municipal, petrochemical, and industrial pipeline projects, holding CE and ISO international certifications, and has been stably exported to the Middle East, Africa, Central Asia, and other global regions for cross-border EPC engineering applications.

• Dedicated Dual-Side FBE Protection: Professionally designed for synchronous internal and external epoxy powder spraying, supporting independent inner wall coating, independent outer wall coating, and dual-side synchronous coating processes. The cured FBE coating features ultra-strong chemical stability, effectively resisting corrosion from water, sewage, oil, gas, and various industrial acidic and alkaline media.
• Premium SA2.5 Surface Preparation: Equipped with customized internal and external shot blasting systems and professional dust removal units, stably reaching the international SA2.5 surface cleanliness grade. It thoroughly removes oxide scale, rust, and surface contaminants to maximize epoxy powder adhesion, preventing coating peeling, blistering, and delamination for long-term stable protection.
• Fully Automated PLC Intelligent Operation: Adopts a centralized PLC automatic control system to realize synchronized linkage of all production procedures. Minimal manual intervention significantly cuts labor costs, eliminates human operation errors, and ensures consistent coating thickness, coverage, and finished product quality in mass batch production.
• Energy-Saving & Eco-Friendly Design: Features high-efficiency medium-frequency induction heating technology with fast temperature rise and low energy consumption, greatly reducing operational power consumption. Equipped with complete dust collection and ventilation environmental protection systems to meet global industrial emission standards and green production requirements.
• Stable Output & Low Maintenance: Achieves stable processing capacity, adapting to medium and large-batch pipeline manufacturing demands. Modular integrated equipment structure simplifies daily inspection and maintenance procedures, lowering operational downtime and long-term after-sales costs for factory owners.
• Wide Compatibility & Customization: Supports customized production according to client project demands, including adjustable pipe diameter adaptation range, controllable FBE coating thickness, and flexible production speed, perfectly matching municipal water supply, oilfield gathering, and general industrial pipeline anti-corrosion scenarios.

The standardized working principle of the Huashida FBE epoxy powder coating production line ensures full, uniform and high-adhesion anti-corrosion coating for steel pipes. The complete industrial workflow is as follows:

Automatic steel pipe uploading → Pipe screw conveyor stable transmission → Precision internal & external shot blasting rust removal → Medium-frequency induction uniform preheating → Internal electrostatic FBE epoxy powder spraying → External epoxy powder coating → High-temperature curing & drying → Automatic cooling spray shaping → Pipe end finishing & grinding → Qualified finished pipe unloading. The entire automated workflow avoids manual operation deviations, realizes full coverage of inner and outer pipe walls without dead angles, and forms a dense, wear-resistant and chemically stable FBE protective layer to extend the overall service life of steel pipelines.

Tailored for universal steel pipe anti-corrosion scenarios, the internal external FBE coating line covers diverse global engineering projects. It is widely applied in municipal potable water supply and sewage drainage pipelines, oilfield gathering and crude oil transmission pipelines, natural gas distribution networks, chemical industrial fluid conveying pipelines, buried outdoor steel pipe anti-corrosion projects, and general factory standardized coated steel pipe mass production, delivering reliable long-term corrosion protection for various low and medium-pressure pipeline systems.
