Customizable 3LPE Coating Pipe Production Line for Advanced and Precise Pipe Coating

Product Description:

3LPE Steel Pipe Coating Production Line
Product Overview:
The 3LPE (Three-Layer Polyethylene) Steel Pipe Coating Production Line by Qingdao Huashida Machinery Co., Ltd. is engineered for high-performance anti-corrosion coating of steel pipes. This line supports pipe diameters ranging from 159mm to 1400mm, with an extrusion capacity up to 350 kg/h, customizable to specific production requirements.

This advanced production line is the result of years of dedicated development and innovation, fulfilling the increasing market demand for durable, efficient, and high-performance anti-corrosion solutions.

3-Layer PE Coating System Composition:
The 3LPE anti-corrosion coating system comprises:
1. Fusion-Bonded Epoxy (FBE) Primer Layer
- Thermosetting, non-toxic coating that cures into a high molecular weight, cross-linked structure.
- Provides excellent chemical corrosion resistance and superior adhesion.
2. Polymer Adhesive Middle Layer
- Typically a polyolefin copolymer (e.g., vinyl copolymer) that chemically bonds with both the epoxy primer and polyethylene top layer.
3. Polyethylene (PE) Top Layer
- Ensures high mechanical protection and environmental resistance, ideal for buried pipelines.

This 3-layer coating structure ensures superior adhesion, excellent mechanical strength, and long-lasting anti-corrosion performance, making it widely used in oil & gas pipelines, urban gas distribution, and water transmission lines.

Technical Process Flow:
1. Pipe Loading
2. Screw Conveyor Transfer
3. Surface Cleaning & Induction Heating
4. Epoxy Powder Coating
5. Adhesive and Polyethylene Extrusion Coating
6. Cooling Spray Treatment
7. Pipe Unloading & Grinding

Key Specifications:
- Pipe Diameter Range: 159mm - 1400mm
