3LPE Coating Pipe Production Line for Corrosion Resistant Pipes with 325-3600mm

(325-3600mm) External 3LPE Internal FBE Steel Pipe Coating Machinery for Oil and Gas Pipelines

Internal & External FBE Powder Coating: Epoxy powder, a thermosetting and non-toxic coating material, forms a high-molecular cross-linked structure after curing. This coating combines excellent chemical anti-corrosion performance with strong mechanical strength, making it ideal for steel pipeline protection. Its base layer bonds and cures firmly on the steel pipe surface, forming a continuous and dense protective layer that delivers superior adhesion, chemical corrosion resistance, and cathodic disbondment resistance. The polymer adhesive bonds the epoxy powder before gelation and connects tightly with the polyethylene top layer, integrating the three-layer structure into a unified and reliable protective whole.

Product Characteristics

1. Efficient Anti-Corrosion Technology: Epoxy powder anti-corrosion treatment on both the inner and outer surfaces of steel pipes ensures excellent chemical corrosion resistance and an extended anti-corrosion service life, suitable for long-term use in harsh environments.

2. Superior Coating Performance: The coating features a smooth surface and low friction, which improves medium transportation efficiency and reduces energy consumption during operation, bringing cost-saving benefits to users.

3. Wide Application Fields: It is the preferred anti-corrosion solution for key projects such as oil and gas transportation, water supply and drainage pipelines, and other infrastructure projects that require reliable pipeline protection.

Main Equipment of 3PE anti-corrosion coating processing

Process Adaptability

It supports separate spraying or composite coating of inner and outer walls (such as outer 3LPE and inner FBE), which can meet different application scenarios, including civil water supply and long-distance oil and gas transportation projects.

Efficient and Stable Performance

The intermediate frequency heating system has a temperature control accuracy of ±2ºC, ensuring uniform melting and adhesion of the powder. The rotational speed of the spiral conveying system is adjustable, which can adapt to the conveying efficiency of steel pipes with different diameters, ensuring stable and consistent processing quality.

Environmental Compliance

The powder recovery device complies with CE and ISO14001 environmental standards, effectively avoiding dust pollution and meeting global environmental protection requirements for industrial production.

Global Service Network

We have completed more than 50 projects at home and abroad, with our equipment installed and put into use in countries such as Russia, Iran, the United Arab Emirates, India, Belarus, and Kazakhstan, gaining wide recognition from global clients.
