50-4200mm Pipe Diameter 3LPE Coating Production Line with SA2.5 Blasting Grade and PLC Control for 3PE Pipe Coating Line

The 3LPE anti-corrosion coating production line provides an efficient method for applying epoxy powder to the internal and external surfaces of steel pipes. The resulting anti-corrosive steel pipe offers strong coating corrosion resistance against a wide range of chemical media, while its smooth surface keeps friction low. These pipes are widely used in petroleum and natural gas transmission pipelines, water supply and drainage systems, and many other fields.

The Steel Pipe Internal & External FBE Powder Coating process involves blasting both the internal and external walls of steel pipes, followed by the application of FBE epoxy powder coating. This process is particularly suited for water supply applications in civil use.

1. Internal Wall Blasting: Prepares the surface by removing contaminants and enhancing adhesion.
2. External Wall Blasting: Provides similar preparation for the outer surface, ensuring a strong bond with the coating.
3. FBE Epoxy Powder Coating: Applied to create a protective layer that offers excellent corrosion resistance.

• Thermosetting Non-Toxic Coating: Upon solidification, it forms a high molecular weight cross-linking structure, enhancing durability.
• Chemical Anticorrosion: Provides strong resistance against various corrosive substances.
• Higher Mechanical Properties: Ensures improved strength and resilience.

• Bottom Layer (Epoxy Powder): Forms a continuous coating that adheres well to the steel surface and offers excellent chemical resistance and cathodic disbonding resistance.
• Polymer Adhesive Layer: Binds the epoxy powder before gelation and unites the epoxy bottom layer with the polyethylene top layer, ensuring structural integrity across all three layers.

This advanced coating system effectively protects steel pipes used in water supply, significantly extending their service life and performance.

We can also build an external 3LPE with internal FBE powder coating line.
