Automatic PLC Controlled 3LPE Coating Pipe Production Line with Shot Blasting Surface Preparation

Integrated Automation

The entire production line is controlled by a centralized PLC and microcomputer system, ensuring synchronized operation and stable production efficiency.

Superior Surface Preparation

High-speed internal and external shot blasting technology removes rust and contaminants, ensuring optimal coating adhesion.

Durable Coating Application

Advanced electrostatic powder spraying technology provides a uniform, impact-resistant anti-corrosion layer.

Strong External Protection

The 3LPE polyethylene extrusion coating forms a high-performance barrier against soil corrosion, moisture, and mechanical stress.

Efficient Internal Coating

The FBE internal powder coating system ensures energy-efficient application and complete coverage for long-term pipeline protection.

External 3LPE & Internal FBE Coating Line Process:
Upload pipe → Pipe screw conveyor → Internal rust removal → External rust removal → Medium frequency heating → Internal epoxy powder coating → External epoxy powder coating → Outer layer bonding polyethylene coating → Cooling spraying → Pipe screw conveyor → Pipe end face grinding → Unloading pipe.

Global Reach:
The 3PE production line has been exported to countries such as Iran, Russia, Saudi Arabia, and Nigeria, receiving high praise from international clients.

After-Sales Service:
√  Warranty: 12 months for mechanical parts, 6 months for electrical components.
√ Support: Technical services, operator training, and guidance are provided.

Customization Options:
The production line can be customized for different pipe diameters, coating thicknesses, and production speeds to meet specific requirements.
