Product Overview
The 3LPE/FBE anticorrosion insulation pipeline coating system is specifically engineered for oil and gas pipelines, offering superior protection against corrosion and environmental damage.
3PE Steel Anticorrosion Pipe Coating Production
Our 3PE anti-corrosion coating production line features a three-layer PE anti-corrosion structure, with a diameter range of φ50 ~ φ4200, designed for comprehensive pipeline protection.
Qingdao Huashida Machinery Co., Ltd. offers customized production capabilities to meet diverse customer requirements for high-performance 3PE coating solutions.
Coating Structure
- First Layer: Fusion-bonded epoxy powder (FBE > 120µm)
- Second Layer: Adhesive (AD) 170 ~ 250µm
- Third Layer: Polyethylene (PE) 1.8 ~ 4.2mm
Key Features
- Extends pipeline lifespan from 5-10 years to 50-100 years
- High mechanical strength with excellent electrical insulation properties
- Waterproof, wear-resistant, and anti-aging characteristics
- Ideal for harsh environments and corrosive conditions
- Energy-efficient sealing reduces operational costs and environmental impact
Applications
This system is widely used in gas and oil transmission lines, municipal gas supply systems, water pipes, and other fluid transport conduits, enhancing mechanical capabilities while providing superior protection.
