Industrial 3LPE Pipeline Coating Plant for Oil & Gas Industry

The automatic steel pipe anti-corrosion coating production line is specially designed for applying high-performance anti-corrosion coatings to steel pipes of different diameters. It is widely used in oil, gas, district heating, water transmission, and other pipeline engineering industries.

The production line is suitable for:

• FBE coating
• Double-layer FBE coating
• 2PE / 2PP coating
• 3LPE coating
• 3LPP coating

The 3-layer PE anti-corrosion structure consists of:

1. Fusion Bonded Epoxy (FBE) primer layer
2. Copolymer adhesive middle layer
3. Polyethylene (PE) outer layer

The complete line integrates shot blasting, dust removal, induction heating, epoxy powder spraying, PE/PP extrusion coating, cooling, conveying, beveling, and automatic control into a fully automatic production system.

• Adopt advanced international coating technology
• Stable operation and high production efficiency
• High degree of automation, reducing labor costs
• Excellent anti-corrosion quality meeting international standards
• Provide complete services including process design, installation, commissioning, and technical training to help customers quickly start production
• Share experience from more than 389 production lines worldwide
• Supported by a professional technical team of 9 senior engineers
• Equipped with a domestic high-end expert workstation for plastic machinery and equipment research and development

The combination of epoxy powder, adhesive, and PE/PP layers provides:

• Strong adhesion
• Excellent chemical corrosion resistance
• Low water absorption
• Outstanding wear resistance
• Reliable cathodic disbondment resistance

This coating structure is widely recognized in the pipeline industry for its stable quality, long service life, and cost-effective operation.

The production line adopts a PLC automatic control system equipped with multiple sensors to monitor pipe position, running speed, production efficiency, and energy consumption. This ensures high-precision operation, stable processing, and consistent coating quality.

The equipment is easy to operate and maintain, with stable operation and a service life of up to 30-50 years.

The production line features efficient sealing systems, dust collection devices, and environmental protection ventilation equipment to reduce energy consumption and improve the working environment.

The coating maintains excellent mechanical properties and impact resistance even under low-temperature conditions.
