Huashida steel pipe internal & external epoxy coating equipment adopts advanced metering spray technology to ensure uniform coating, improving corrosion resistance and extending pipeline service life. The line is equipped with a PLC automatic control system for stable and efficient operation.
Epoxy powder coating delivers unparalleled corrosion protection through its smooth, low-friction surface. This exceptional quality makes it the preferred choice for oil & gas transmission, as well as water supply and drainage pipelines, offering durability and reliability under the most challenging conditions.
Production Line Specifications
Applicable Steel Pipe Diameter: 114 mm - 4200 mm
Production Capacity: Up to 250 m²/h
Surface Preparation Standard: Sa 2.5 (Shot Blasting Cleaning)
Coating Material: Fusion Bonded Epoxy (FBE) Powder
Internal & External FBE coating Structure:
Epoxy powder is a thermosetting, non-toxic coating that, after curing, forms a high-molecular-weight cross-linked coating with excellent chemical corrosion resistance and high mechanical properties. The epoxy powder primer forms a continuous coating, providing excellent adhesion to the steel pipe surface through bonding and curing, and exhibiting excellent chemical resistance and cathodic disbondment resistance. The polymer binder bonds the epoxy powder before gelation and also bonds the polyethylene topcoat, combining the three layers together.
Advantages of production line:
1. The internal powder coating line is equipped with an electrostatic spraying system to avoid pinholes in the internal coating caused by spray gun discharge.
2. The dust collection system provides comprehensive coverage, enabling multi-point environmental control.
3. The external powder coating line adopts a closed-loop powder circulation system, improving recovery rate and cleanliness.
4. The dust collection system features a reasonable airflow, and the filter cartridges are highly efficient, low-noise, environmentally friendly, and energy-saving.
