| High Light | Automated 3PE Coating Line ，PLC Intelligent Control Anti-Corrosion Coating Production Line ，4-6 Times D Curvature Radius Steel Elbow Coating Equipment | ||
The Qingdao Huashida Steel Elbow 3PE Anti-Corrosion Production Line is specially designed for the external anti-corrosion coating of steel elbows, hot-bent pipes, and curved steel pipes. It is widely used in industrial applications such as:
This production line integrates multiple key processes into one efficient and continuous workflow, including:
The anti-corrosion structure adopts the standard 3PE coating system:
This structure provides excellent corrosion resistance, strong adhesion, high mechanical protection, and long service life, making it an ideal solution for industrial pipeline protection.
The line is equipped with at least 16 sets of elbow pipe conveying structures, on which the curved pipes are placed and transported during the coating process.
The rotating shaft of the driving mechanism is powered by a motor to rotate the gear ring, enabling the elbow pipe to rotate smoothly around its center. The supporting rubber roller can be adjusted in height through the lifting device of the conveying structure, allowing the system to adapt to different pipe diameters while maintaining a uniform center height.
This design ensures:
Stable pipe conveying
Smooth and synchronized pipe rotation
Accurate heating and coating
High production efficiency
The complete system is suitable for curved steel pipe blasting, coating, and PE layer wrapping, with the anti-corrosion form of:
Epoxy Powder + Adhesive + PE Tape
| Item | Name | Specification |
|---|---|---|
| 1 | Steel Pipe Diameter | 426, 630, 720, 820, 1000, 1200 mm |
| 2 | Curvature Radius | 4–6 times pipe diameter (D) |
| 3 | Elbow Angle | 15°–90° |
| 4 | Steel Pipe Wall Thickness | 8–12 mm |
| 5 | Epoxy Powder Thickness | ≥170 μm |
| 6 | AD Copolymer Adhesive Thickness | 170–250 μm |
| 7 | PE Layer Thickness | 2.5–3.7 mm |
The elbow conveyor line is specially designed for the smooth transportation and rotation of curved steel pipes during blasting, heating, coating, and wrapping.
This system ensures stable movement and accurate positioning of elbow pipes throughout the production process.
The intermediate frequency heating system ensures uniform and efficient heating of elbow pipes before coating.
This system guarantees stable heating performance and helps improve coating adhesion and quality.
The powder spraying system is designed for precise and uniform application of FBE epoxy powder on the curved pipe surface.
This system ensures even powder distribution and excellent coating consistency.
The powder recovery system improves powder utilization and maintains a cleaner production environment.
This system helps reduce material waste and increase operating efficiency.
The winding machine is used for wrapping the PE outer protective layer around the elbow pipe after the epoxy and adhesive coating process.
This system ensures compact, even, and reliable PE layer wrapping.
The entire production line is equipped with an advanced PLC intelligent control system for automatic operation and process management.
The PLC system improves automation, reduces labor intensity, and ensures stable product quality.
Awarded as the First (Set) Technical Equipment in Shandong Province, demonstrating strong technical innovation and manufacturing capability.
The production line is designed for reliable operation, stable performance, and consistent coating quality.
Advanced automation significantly reduces manual labor, improves safety, and enhances production efficiency.
