Product Description

Product Description

This specialized equipment is designed for surface treatment and 3-layer polyethylene (3PE) coating of hot bend pipes, along with compatible section steel and structural components. The integrated production line combines shot blasting, intermediate frequency heating, 3PE coating, and rapid cooling into a continuous automated process. It effectively removes surface rust, welding slag, and stress while enhancing coating adhesion to significantly improve mechanical performance and anti-corrosion longevity.

Core Components

1.Pipe Conveying System

Ensures smooth and stable transportation throughout the entire coating process

2.Shot Blasting Machine

Completely removes scale, welding slag, and increases surface roughness for superior coating adhesion

3.Intermediate Frequency Heating System

Precise temperature control ensures optimal epoxy powder fusion and coating curing

4.3PE Coating System

           Fusion Bonded Epoxy (FBE) Layer: Chemical corrosion resistance with high-strength bonding

           Adhesive Layer: Bonds epoxy to polyethylene with exceptional interlayer adhesion

           Polyethylene (PE) Layer: Impact-resistant, abrasion-proof, and moisture-proof for harsh environments

5.Spray Cooling System

Rapid solidification for improved coating quality and surface finish
