The Internal FBE & External 3LPE Anti-Corrosion Coating Production Line developed by HUASHIDA is specially designed for applying advanced anti-corrosion coatings to steel pipes of various diameters. This integrated system provides reliable internal and external protection, significantly improving the durability and service life of pipeline infrastructure.
This production line is widely used in various pipeline engineering projects, including:
The internal FBE (Fusion Bonded Epoxy) coating provides excellent adhesion, chemical resistance, and corrosion protection for the inner surface of the steel pipe. At the same time, the external 3LPE (Three-Layer Polyethylene) coating system forms a strong multi-layer barrier that protects the pipe against moisture, soil pressure, mechanical impact, and corrosive environments.
After coating, the steel pipe surface becomes smooth, uniform, and highly resistant to wear and corrosion. This not only improves the efficiency of fluid transportation by reducing friction, but also greatly extends the pipeline’s service life.
The coating line mainly consists of the following units:
Pipe loading → Spiral conveyor → Internal rust removal → External rust removal → Medium-frequency heating → Internal epoxy powder coating → External epoxy powder coating → Adhesive & polyethylene outer coating → Water cooling → Pipe conveying → Pipe end beveling / grinding → Pipe unloading
This complete process ensures that both the inner and outer surfaces of the steel pipe are treated and coated efficiently, accurately, and consistently.

The 3-layer polyethylene anti-corrosion coating technology is one of the most advanced protective solutions for buried steel pipelines. It is widely used in:
The 3LPE anti-corrosion coating significantly improves the pipeline’s:
It provides long-term protection and ensures reliable performance in harsh operating environments.
The entire production line is controlled by a centralized PLC and microcomputer system, ensuring synchronized operation, stable production, and high efficiency.
Advanced internal and external shot blasting technology effectively removes rust, oxide scale, and contaminants, ensuring excellent coating adhesion.
The electrostatic powder spraying system delivers a uniform, dense, and impact-resistant anti-corrosion layer.
The 3LPE polyethylene extrusion coating forms a highly durable barrier against soil corrosion, moisture, and mechanical stress.
The internal FBE powder coating system provides complete and energy-efficient coverage for long-term internal corrosion protection.
The combined internal and external anti-corrosion system effectively extends the pipeline’s operational lifespan and reduces maintenance costs.
