Automatic PLC Controlled 3LPE Coating Pipe Production Line with Internal FBE and External 3LPE Protection

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.

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

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

• Oil and gas transmission pipelines - protecting pipelines from corrosion and mechanical damage during long-distance transportation
• Urban gas distribution systems - ensuring safe and reliable gas delivery in municipal networks
• Municipal water supply pipelines - providing durable protection for drinking water and industrial water pipelines
• District heating pipelines - offering corrosion resistance and durability under high-temperature operating conditions
• Underground fluid transportation pipelines - safeguarding steel pipes used for transporting oil, water, chemicals, and other fluids in harsh buried environments

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.
