Polyethylene Three-Layer Anti-Corrosion Coating Line for Pipes

Product Overview
The 3PE anti-corrosion coating production line is designed for applying a three-layer coating to steel pipes, enhancing their mechanical strength, electrical insulation, and durability. It is ideal for oil, gas, water, and other fluid transmission pipelines.
 
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

Key Customer Benefits:
1. Simplified Operation & Reduced Skill Dependence
Well-known brand PLC control system with large touchscreen and stored diameter recipes enables one-click specification change with automatic parameter setting, significantly reducing dependence on skilled operators and ensuring consistent product quality even with staff turnover.

2. Consistent Coating Quality
Extrusion die with medium frequency induction heating ensures uniform PE coating thickness distribution (tolerance within ±0.1mm ) and reliable adhesion, enabling every pipe to consistently pass international standard inspection and eliminating costly rework and project delivery delays.

3. Reduced Operational Energy Cost
Integrated waste heat recovery system combined with full-line variable frequency drives reduces overall energy consumption by approximately 25% , significantly lowering monthly electricity expenses and improving profit margins over the equipment lifecycle.

4. Professional Installation & Commissioning
Senior engineers with experience in commissioning 200+ production lines provide on-site installation, commissioning, and operator training, ensuring the client's team achieves stable independent production before engineer departure, significantly reducing ramp-up time and operational risks.

5. Wide Diameter Range Coverage
Modular conveying system with adjustable roller spacing enables a single production line to cover a wide diameter range , eliminating the need for multiple equipment investments and allowing clients to accept orders across various pipe specifications without capacity limitations
