Product Description


3 Layer Polyethylene (3LPE) Anti-Corrosion Steel Pipe Production Line for Oil & Gas
3-layer polyethylene (3LPE) anti-corrosion steel pipe
3LPE anti-corrosion steel pipe consists of a three-layer structure, combining advanced technology and high-quality materials to provide excellent anti-corrosion protection for pipelines:
Base layer: epoxy powder coating, which is tightly bonded to the surface of the steel pipe and provides excellent anti-corrosion performance.
Middle layer: copolymer adhesive (with branched functional groups) to ensure that the base layer is firmly bonded to the surface layer.
Surface layer: high-density polyethylene (HDPE), providing mechanical protection, low water absorption and environmental adaptability.
Automatic PLC Controlled 3LPE Coating Pipe Production Line for 50-4200 mm Pipeline Diameter Anti-Corrosion
Our Advantages
Efficient sealing: extremely high sealing performance, long-term operation can significantly save energy, reduce costs and protect the environment.
Excellent anti-corrosion: strong corrosion resistance, simple and fast construction, and a service life of 30-50 years.
Low temperature adaptability: still has good corrosion resistance and impact resistance in low temperature environment.
Material characteristics: combined with the high strength of epoxy powder, the low water absorption of polyethylene and the flexibility of hot melt adhesive, it ensures high reliability.
Economical and efficient: simple production process, excellent anti-corrosion effect, high cost performance, and meets international standards.
