Product Description

Hot Bending Pipe 3PE Coating & Shot Blasting Integrated Line

This equipment is specially designed for the surface treatment and 3-layer PE (3PE) coating of hot bending pipes, as well as certain section steel and structural parts with suitable dimensions. The integrated production line combines shot blasting, intermediate frequency heating, 3PE coating, and rapid cooling into one continuous process. It effectively removes surface rust, welding slag, and stress, while enhancing coating adhesion and improving the overall mechanical and anti-corrosion performance of the pipe.

Key Components
Pipe Transportation System
Ensures smooth and stable movement of the pipes throughout the entire coating process.

Shot Blasting Machine
Removes rust, oxide scale, and welding slag from the pipe surface to improve coating adhesion and surface roughness.

Intermediate Frequency Heating System
Maintains optimal pipe temperature to ensure proper fusion and curing of each coating layer.

3PE Coating System
Precisely applies the three coating layers: Fusion Bonded Epoxy (FBE), adhesive, and polyethylene (PE), ensuring strong bonding and consistent coverage.

Spray Cooling System
Rapidly cools and solidifies the coating layer, improving adherence and surface finish.

Coating Structure - 3-Layer PE
Fusion Bonded Epoxy (FBE) Layer
Provides excellent chemical resistance and strong adhesion. It forms a high-strength, cross-linked molecular structure after curing.

Adhesive Layer
Acts as a bonding bridge between the epoxy layer and polyethylene outer layer, ensuring cohesive strength across all three layers.

Polyethylene (PE) Outer Layer
Offers excellent resistance to abrasion, mechanical impact, and moisture. It serves as the main protective barrier in underground or exposed pipeline environments.

Product Parameters

The equipment is suitable for hot bend pipes with diameters of 426 mm, 630 mm, 720 mm, and 820 mm.
It supports bending radii of 4D to 6D and angles between 15 and 90 degrees.
Pipe wall thickness should range between 8 mm and 12 mm.
The coating thickness meets international anti-corrosion standards:

Epoxy powder layer ≥170 μm

Adhesive layer 170-250 μm

Polyethylene outer layer 2.5-3.7 mm

General equipment dimensions are approximately 20 meters by 15 meters.
Water consumption is around 30 cubic meters per cycle.
Total power consumption is 450 kilowatts, and gas usage is about 6 cubic meters per minute.
The recommended operating temperature inside the workshop should be no less than 5°C.
