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.
Production Process

Technical Details
Corrosion-resistant steel pipes are categorized into internally
treated and externally treated types. Internally treated pipes use
protective coatings, while externally treated pipes primarily
feature 3PE coating technology.
Qingdao Huashida's 3PE anti-corrosion production line utilizes
mature technology to provide effective protection for both pipe
interiors and exteriors. Suitable for various pipe types including
straight-seam and spiral pipes, our production line features a
comprehensive ISO9001-certified quality assurance system.
Qingdao Huashida Machinery Co., LTD., founded in 2003, is a global developer, manufacturer and solution
provider of plastic extrusion equipment. 70% of our customers come
from overseas markets including Europe, America, the Middle East
and Southeast Asia.
