Automated 3LPE Coating Pipe Production Line with SA 2.5 Surface Treatment and Polyethylene Coating

The Huashida 3LPE/FBE Steel Pipe Anti-Corrosion Coating Line is a comprehensive, fully automated solution for applying high-performance protective layers to steel pipelines. This complete system integrates advanced shot blasting, precision intermediate-frequency heating, electrostatic powder spraying, and O-type co-extrusion technology for PE and adhesive applications.

Engineered for extreme environments, the 3LPE-coated pipes produced on this line offer superior resistance to chemical degradation, acids, bases, and salt solutions. This ensures maximum stability and an extended service life for critical infrastructure in oil and gas transmission, municipal water management, and industrial fluid transportation.

Our streamlined workflow ensures uniform coating thickness and high-speed output:

1. Pipe Loading: Automated upload via screw conveyor.

2. Surface Treatment: Professional rust removal (Sa2.5) via shot blasting.

3. Induction Heating: Precision intermediate frequency heating for optimal coating adhesion.

4. FBE Coating: Electrostatic Epoxy powder spraying.

5. 3LPE/2LPE Application: O-Type co-extrusion of adhesive and polyethylene layers.

6. Cooling & Finishing: Water spray cooling followed by automated pipe end grinding/beveling.

7. Unloading: Systematic discharge for storage and transport.
