Automatic 3LPE Coating Pipe Production Line with PLC Control System and FBE Epoxy Powder Coating

The Internal FBE & External 3LPE Anti-Corrosion Coating Production Line developed by HUASHIDA is designed to apply advanced protective coatings to steel pipes of different diameters. This system ensures reliable corrosion protection and enhances the durability of pipeline infrastructure.

The production line is commonly used in various pipeline engineering projects, including:

District heating pipeline systems

Natural gas transmission pipelines

Municipal water supply pipelines

Oil and other fluid transportation pipelines

The internal FBE coating offers excellent adhesion and chemical resistance, effectively protecting the inner surface of the pipe. Meanwhile, the external 3LPE coating system provides a strong multi-layer protective barrier that resists moisture, soil pressure, and corrosive environments.

After coating, the pipe surface becomes smooth and uniform, which helps reduce friction during fluid transportation and improves pipeline efficiency while significantly extending service life.

Integrated Automation

The entire production line is controlled by a centralized PLC and microcomputer system, ensuring synchronized operation and stable production efficiency.

Superior Surface Preparation

High-speed internal and external shot blasting technology removes rust and contaminants, ensuring optimal coating adhesion.

Durable Coating Application

Advanced electrostatic powder spraying technology provides a uniform, impact-resistant anti-corrosion layer.

Strong External Protection

The 3LPE polyethylene extrusion coating forms a high-performance barrier against soil corrosion, moisture, and mechanical stress.

Efficient Internal Coating

The FBE internal powder coating system ensures energy-efficient application and complete coverage for long-term pipeline protection.

Oil and gas transmission pipelines - providing long-term protection against corrosion and external damage.

Urban gas and water supply systems - ensuring safe and reliable transportation of fluids.

District heating networks - offering excellent insulation and corrosion resistance under high temperatures.

Underground and industrial anti-corrosion projects - protecting buried or exposed steel pipelines in harsh environments.
