The Huashida Steel Elbow 3PE Coating Line is engineered for the external anti-corrosion coating of steel elbows, hot bends, and other curved steel pipe sections.
Designed for demanding pipeline applications, this line is widely used in industries such as:
It combines all major coating stages into one integrated production system, including:
The line is built to deliver a consistent 3-layer PE anti-corrosion coating system (3PE):
The result is a durable coating structure with strong adhesion, excellent corrosion resistance, and reliable long-term protection for harsh operating environments.
The production line is configured with 16 or more elbow pipe support and conveying stations, allowing curved pipe sections to move steadily through each stage of the process.
Each elbow is supported and rotated around its center by a dedicated drive mechanism. The system uses a motor-driven gear ring transmission to ensure smooth and controlled rotation during blasting, heating, powder coating, and wrapping.
To accommodate different pipe sizes, the support roller height can be adjusted through the lifting mechanism, maintaining a stable and consistent centerline throughout production.
This design helps ensure:
The full anti-corrosion structure consists of:
FBE Powder + Adhesive + PE Tape
| Item | Parameter | Specification |
|---|---|---|
| 1 | Pipe Diameter | 426 / 630 / 720 / 820 / 1000 / 1200 mm |
| 2 | Bend Radius | 4–6D |
| 3 | Elbow Angle | 15°–90° |
| 4 | Pipe Wall Thickness | 8–12 mm |
| 5 | FBE Coating Thickness | ≥170 μm |
| 6 | Adhesive Layer Thickness | 170–250 μm |
| 7 | PE Layer Thickness | 2.5–3.7 mm |
The conveyor system is specially designed for the controlled handling and rotation of curved steel pipes.
This ensures stable pipe positioning throughout the entire coating process.
The heating system brings the steel surface to the required process temperature before coating.
This system helps achieve stable heating performance and improved coating quality.
The powder coating unit is designed for precise application of Fusion Bonded Epoxy (FBE) onto curved steel pipe surfaces.
This setup supports uniform coating thickness and efficient powder application.
The recovery system is designed to maximize powder utilization and maintain a cleaner production environment.
This helps reduce powder loss and improve operational efficiency.
The wrapping unit applies the outer PE protective layer after powder coating and adhesive application.
The system is designed to produce a compact and uniform outer layer on curved pipe surfaces.
The entire line is managed by an integrated PLC control platform, enabling automated operation and process monitoring.
This improves repeatability, reduces operator dependency, and supports more stable production.
Built for real-world pipe coating applications with a focus on process stability, automation, and coating consistency.
Unlike straight-pipe-only systems, this line is specifically developed for elbows and bend sections, where coating control is more demanding.
The integrated system reduces manual handling, improves production flow, and supports more consistent coating quality.
