Automatic PLC Control 3LPE Coating Pipe Production Line with Shot Blasting for Anti-Corrosion

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.
