Product Description
This Automatic O-Type 3LPE FBE Steel Pipe Coating Line is purpose-built for small diameter municipal pipeline coating across a 76-325mm diameter range. Unlike spiral-conveyor large-diameter coating lines, this automatic O-Type round-die co-extrusion coating line delivers uniform, continuous 3LPE coating thickness around the full pipe circumference without manual adjustment between pipe sizes.
The line includes fully integrated systems for steel pipe transmission, external shot blasting to Sa2.5 international surface cleanliness, dust collection, medium-frequency induction preheating, electrostatic FBE epoxy powder spraying, hot melt adhesive extrusion, 3LPE/2LPE polyethylene outer layer co-extrusion, water spray cooling, automated pipe end grinding/beveling, hydraulic/pneumatic operation, inspection, and full PLC automatic control - all managed by one operator.
Coating Structure
First Layer: Fusion-bonded epoxy powder (FBE > 100µm)
Second Layer: Adhesive (AD) 170 ~ 250µm
Third Layer: Polyethylene (PE) 2.5 ~ 3.7mm
Key Features
Enhances pipe lifespan from 5-10 years to 50-100 years
High mechanical strength, excellent electrical insulation, waterproof, wear-resistant, and anti-aging properties
Suitable for harsh environments and corrosive conditions
Technological Process
Pipe Input: Upload pipes
Conveying: Pipe screw conveyor
Rust Removal: Intermediate frequency heating
Coating: Epoxy powder coating, adhesive, and polyethylene
Cooling: Spray cooling system
Finishing: Grinding and unloading pipes
