Small Diameter Continuous O-Type Extrusion 3LPE FBE Steel Pipe Coating Line

This automatic O-type extrusion 3LPE steel pipe anti-corrosion coating line, featuring core FBE 3LPE coating equipment for small-bore pipelines, integrates full-process shot blasting derusting, intermediate-frequency induction heating, electrostatic FBE epoxy powder spraying and patented O-type co-extrusion to finish complete 2LPE & 3LPE anti-corrosion coating in one continuous production flow.

Finished pipes gain robust acid, alkali and salt corrosion resistance thanks to standard three-layer anti-corrosion structure, making this steel pipe coating machine ideal processing equipment for oil & gas transmission, municipal water supply and industrial fluid buried pipeline engineering.

Standardized automatic workflow guarantees consistent coating thickness and tight bonding for reliable anti-corrosion performance:

1. Pipe Loading: Automated screw conveyor pipe feeding
2. Surface Treatment: Shot blasting rust removal up to Sa2.5 standard
3. Induction Heating: Precise intermediate frequency heating for enhanced FBE adhesion
4. FBE Coating: Electrostatic epoxy powder spraying for base anti-corrosion layer
5. 3LPE/2LPE Application: O-type co-extrusion for adhesive and outer PE protective layers
6. Cooling & Finishing: Water spray cooling plus automatic pipe end beveling
7. Unloading: Orderly finished pipe discharging and storage
