Product Description
3LPE/3LPP Fusion Bonding Epoxy Coating System
3PE anti-corrosion coating provides triple-layer protection for steel pipes, extending service life from 5-10 years to 50-100 years. The system consists of:
- First layer: Fusion bonded epoxy (FBE > 100µm)
- Second layer: Adhesive (AD) 170-250µm
- Third layer: Polyethylene (PE) stripe 2.5-3.7mm
Key Features
- High mechanical strength
- Excellent electrical insulation performance
- Process accuracy
- Environmental friendliness
Applications
The three-layer HDPE stripe winding process, with epoxy powder coating as bottom layer and binding adhesive as second layer, is the widely used technique in steel pipe anti-corrosion worldwide. These anti-corrosion steel pipes are applied in oil, gas, and water supply pipelines.
Three-Layer Structure
The three-layer PE anti-corrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer, and polyethylene outside layer. The epoxy powder is a thermosetting nontoxic coating, forming high molecular weight cross-linking structure coating after solidifying, featuring excellent chemical anti-corrosion and high mechanical properties.
Layer Functions
- Epoxy Layer: Forms continuous coating and provides steel tube surface with chemical resistance and cathodic disbanding resistance
- Polymer Adhesive: Bonds epoxy layer and polyethylene outside layer, uniting all three layers together
- Polyethylene Layer: Protects pipe from abrasion, impact, and water
Technological Process
Upload pipes → Pipes conveyor → Rust removal → Intermediate frequency heating → Epoxy powder coating → Middle layer & polyethylene stripe winding → Water cooling → Pipes conveyor → Pipe chamfer → Unload pipes
