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.
Application Fields The 3LPE coating line is widely applied in:
Oil and gas transportation pipelines Urban gas distribution networks Water supply systems Industrial fluid pipelines
