Product Description


Pipeline Anti-Corrosion Coating Line with External 3LPE and Internal FBE Technology
The Steel Pipe Internal FBE & External 3LPE Anti-Corrosion Coating Production Line manufactured by HUASHIDA is designed for applying high-performance corrosion protection coatings to steel pipes of various diameters.
This pipeline coating production line is widely used in engineering projects such as:
District heating pipelines
Natural gas transmission pipelines
Water supply pipelines
Oil and fluid transportation pipelines

The internal FBE coating provides strong adhesion and excellent chemical resistance, while the external 3LPE coating forms a durable multi-layer barrier against moisture, soil stress, and harsh environments. The final coating surface is smooth and low-friction, improving flow efficiency and extending the service life of pipelines.
Coating Structure
The coating system combines internal FBE powder coating with external 3-layer polyethylene protection, ensuring long-term corrosion resistance.
Typical coating structure:

Internal Layer: FBE (Fusion Bonded Epoxy) Powder Coating
External Layer:
Epoxy Primer
Adhesive Layer
Polyethylene (PE) Outer Layer

The coating line mainly consists of the following units:
-steel pipe conveyor system
-shot/sand blasting system
-dust collector system
-pipe induction heating system
-epoxy powder spraying system
-PE&Adhesive coating system
-water cooling system
-pipe end cutting system
-hydraulic and pneumatic system
-testing system
-electronic control system
Automatic PLC Controlled 3LPE Coating Pipe Production Line with Internal FBE and External 3LPE 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.
