Bend Pipe 3LPE/2LPE/FBE Anti-Corrosion Coating Line for
Large-Diameter Steel Pipes
This advanced Bend Pipe 3LPE Coating Equipment is designed for the
anticorrosion treatment of large-diameter steel pipes used in oil
and gas pipelines. It efficiently applies 2LPE, 3LPE, and FBE epoxy
coatings to enhance pipe durability and resistance against
chemicals, moisture, and harsh environmental conditions.
Performance characteristics
Product Parameters
Equipmet Features & Technical Specifications| Key Features | Parameter | Value / Description |

Production Process| 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. |
