3LPE Coating Pipe Production Line Offering Complete Solutions for Protective Coating of Steel Pipes
Product Overview
The 3LPE Coating Pipe Production Line is a complete system for pipe coating and corrosion protection, ensuring durable and reliable pipeline solutions.
The three-layer PE process utilizes an epoxy powder coating as the bottom layer and is bonded with polyethylene (PE) and adhesive to provide robust anti-corrosion protection for steel pipes. This method is widely adopted both domestically and internationally for oil and gas pipelines as well as civil gas and water supply systems.
The system is designed to deliver stable coating quality, long-term protection, and efficient production performance for pipeline external corrosion protection projects.

Equipment Features
Extended Service Life: The three-layer PE coating can extend the lifespan of steel pipes from 5-10 years to 50-100 years, greatly improving return on investment.
Excellent Corrosion Resistance: Using epoxy powder as the base layer, combined with polyethylene and adhesive, the coating forms a strong and effective corrosion barrier against environmental exposure.
High Mechanical Strength: The 3PE coating has good mechanical strength and can withstand external impacts and wear, helping protect the pipe integrity.
Good Electrical Insulation: Excellent insulation properties help prevent electrical corrosion, making it suitable for power and communication pipeline environments.
Environmentally Friendly Process: The coating process minimizes pollution and does not release harmful substances, complying with modern environmental standards.
High Degree of Mechanization: The production process is highly mechanized, ensures stable process parameters, improves production efficiency, and reduces labor intensity.
Versatile Applications: Widely used in oil, gas, water supply, and gas supply industries, meeting diverse market needs.
Low Maintenance Costs: Due to durability and corrosion resistance, 3PE-coated pipelines typically require lower long-term maintenance, reducing operational expenses.
Strong Adhesion: The three-layer structure ensures tight bonding between the coating and steel pipe, minimizing peeling and delamination risk.
Good Thermal Stability: Able to withstand high and low temperature conditions while maintaining excellent physical properties under various climatic environments.
