Product Description

Customized 3lpe Anti-Corrosion Coating Machine for Large-Diameter Steel Pipes

Product Description

3LPE (Three-Layer Polyethylene) coated steel pipes consist of a multi-layered structure designed for superior corrosion resistance and durability. The structure includes: First Layer: Fusion-bonded epoxy (FBE) for strong adhesion to the steel and excellent corrosion protection Second Layer: Copolymer adhesive for bonding the epoxy and PE layer Third Layer: High-density polyethylene (HDPE) for mechanical protection This three-layer coating is widely recognized as one of the most effective anti-corrosion systems for buried steel pipelines.

Advantages of 3LPE Coated Pipes
Exceptional Sealing Performance: Reduces energy loss, minimizes maintenance, and extends pipeline life
High Corrosion Resistance: Withstands harsh environments with a service life of 30–50 years
Low-Temperature Impact Resistance: Maintains flexibility and toughness even in cold climates
Excellent Bonding: Combines high epoxy strength, low PE water absorption, and strong adhesive softness
Reliable & Cost-Effective: Simplified production process, low cost, and excellent anti-corrosion effect
Versatile Application: Suitable for gas, oil, water, and other fluid transportation pipelines.
