1 | Bend Pipe Conveyor | Transports the bent pipes smoothly and precisely through each stage of the coating line. |
2 | Bend Pipe Blasting Machine | Prepares the pipe surface by abrasively removing rust, mill scale, and contaminants to ensure optimal coating adhesion. |
3 | Intermediate Frequency Heater | Precisely heats the pipe to a controlled temperature, which is critical for the epoxy fusion and polymer bonding process. |
4 | 3LPE Coating System | Applies the three-layer anti-corrosion coating: Fusion-Bonded Epoxy (FBE), adhesive copolymer, and extruded polyethylene (PE) tape. |
5 | Spraying and Cooling System | Rapidly cools the coated pipe with water sprays to quench and solidify the coating, ensuring proper curing and material properties. |
