Internal FBE + External 3LPE Coating Machinery for Steel Pipelines
Product Overview
Internal & External FBE Powder Coating provides superior protection for steel pipelines. 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.
The 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.
Key Characteristics
- Efficient Anti-Corrosion Technology: Epoxy powder anti-corrosion treatment on both inner and outer surfaces ensures excellent chemical corrosion resistance and extended service life, suitable for long-term use in harsh environments.
- Superior Coating Performance: Features smooth surface and low friction, improving medium transportation efficiency and reducing energy consumption during operation.
- Wide Application Fields: Preferred anti-corrosion solution for key projects including oil and gas transportation, water supply and drainage pipelines, and other infrastructure projects requiring reliable pipeline protection.
Equipment Core Highlights
External 3LPE & Internal FBE Coating Line Process:
Pipe loading → Spiral conveyor → Internal rust removal → External rust removal → Medium-frequency heating → Internal epoxy powder coating → External epoxy powder coating → Adhesive & polyethylene outer coating → Water cooling → Pipe conveying → Pipe end beveling / grinding → Pipe unloading
This complete process ensures that both the inner and outer surfaces of the steel pipe are treated and coated efficiently, accurately, and consistently.
