Surface Preparation and Derusting System - Integrated into 3PE External &
Epoxy Internal Coating Line for Steel Pipes
This high-performance system forms the critical first stage in a complete coating line, ensuring flawless surface quality for superior coating adhesion and long-term pipeline integrity.Core Advantages:
Integrated Efficiency: Seamlessly interfaces with upstream and downstream processes for a continuous, automated production flow.
Exceptional Cleanliness: Achieves near-white metal cleanliness (Sa 2.5 or higher) and optimal anchor profile, essential for 3PE and epoxy coating bond strength.
Robust & Reliable: Engineered with heavy-duty components for 24/7 operation in demanding industrial environments.
Environmentally Compliant: Features efficient abrasive recycling and dust collection systems, minimizing waste and emissions.
The epoxy powder layer provides strong bonding and chemical resistance, while the hot melt adhesive enhances interlayer adhesion. The polyethylene outer coating offers outstanding impact resistance, moisture protection, and durability. With a stable and efficient production process, the line delivers uniform coating thickness and reliable quality.
This 3PE coating line supports a wide range of pipe diameters and can be customized to meet specific project requirements. Featuring automated control, energy-efficient design, and easy operation, it helps manufacturers improve productivity, reduce operating costs, and achieve consistent coating performance.
3-layer PE anti-corrosion coating consists of the first FBE coating, middle adhesive layer, and outer polyethylene layer.
The three-layer polyethylene anti-corrosion coating is advanced technology as the outer protective layer of buried pipe, widely used in the anti-corrosion of gas and oil transmission pipelines, urban gas supply, water supply pipes, and other fluid transmission pipelines. 3-layer PE anti corrosion coating can strengthen the pipeline's mechanical properties with high electrical resistance, waterproof, wearable, and anti-aging performance. The anti-corrosion coating processing line includes: -steel pipe transmission system -surface treatment system -pipe dust removal system -pipe heating system -electrostatic spraying system -coating system -water cooling system -end cutting system -hydraulic and pneumatic system -testing system -electronic control system.
