Product Description

Product Description


Customized Automatic 3LPE Coating Pipe Production Line for Large-Diameter Steel Pipes 0
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.

5 stars for this high-performance HDPE jacket pipe extrusion line! It works perfectly with PU foam pre-insulated pipe systems, creating strong, weather-resistant outer casing for municipal and industrial heating projects. The extruder is powerful, forming is one-time finished, and raw material utilization rate is very high. Stable continuous operation, solid mechanical design, and great cost performance. Exactly what our pipeline manufacturing plant needed.
