3PE Coating Equipment Line for Steel Pipe Bending with Powder Coating and 170-250 Um Adhesive Thickness for 15-90 Degrees Elbow Angle

The 3PE Coating Equipment Line for Steel Pipe Bending is an advanced industrial solution designed to apply high-performance three-layer polyethylene (3PE) anti-corrosion coating on bent steel pipes. Engineered for precision and durability, this system ensures consistent coating quality even on complex pipe geometries, making it ideal for pipelines used in oil, gas, water supply, and infrastructure projects.

This specialized 3PE coating line is developed to handle steel pipe bends and elbows, overcoming the challenges of non-linear surfaces. The system integrates surface preparation, epoxy powder spraying, adhesive application, and polyethylene wrapping into a seamless automated process. Equipped with intelligent control systems and precision coating technology, it guarantees uniform thickness, strong adhesion, and long-term corrosion resistance.
