3LPE Coating Pipe Production Line pipe external polyethylene coating plant

3LPE Coating Pipe Production Line pipe external polyethylene coating plant 

3PE 3LPE anti-corrosion coating production lines are engineered to coat steel pipes with diameters ranging from 57 mm to 3000 mm, making it suitable for a wide range of applications in heating systems, gas transmission, oil pipelines, and various construction projects.

The line supports multiple coating systems, including:

• FBE (Fusion Bonded Epoxy)

• 2-Layer FBE & 2-Layer PE

• 2-Layer PP

• 3-Layer PE

3-Layer PE Anti-Corrosion Coating System
Composed of an inner FBE layer, a middle adhesive layer, and an outer polyethylene sheath, the 3-layer PE coating offers superior protection for buried and submerged pipelines. Widely adopted in oil and gas transmission, urban gas and water supply networks, and other fluid transportation systems, this technology significantly enhances the mechanical strength, electrical insulation, waterproofing, wear resistance, and aging resistance of pipelines—ensuring long-term reliability and operational safety.

Automated Production Workflow:

1. Pipe Loading & Alignment

2. Shot Blasting (Surface Preparation)

3. Medium-Frequency Induction Heating

4. FBE Powder Application

5. Adhesive & PE Extrusion Coating

6. Water Cooling & Curing

7. Pipe End Beveling & Finishing

8. Final Unloading & Inspection

Designed for high throughput and consistent quality, this system features precise temperature control, automated material handling, and an environmentally conscious operating process, making it a reliable choice for modern pipeline coating requirements.
