metal pipe 3 layer PVC coating extrusion machine

The YAOAN metal pipe 3 layer PVC coating extrusion machine is a specialized solution designed for coating metal pipes (such as steel pipes and aluminum pipes) with plastic layers. The plastic coating can be made of PE, PP, PVC, or ABS, and the aluminum pipe coating line can produce pipes with 1-color, 2-color, 3-color, or multi-layer coatings based on client requirements. Below is a detailed description of its features, applications, and configuration:

Key Features of Steel Pipe Plastic Coating Lines:

• Coating Materials: PE, PP, PVC, ABS, TPE, TPR.

• Coating Layers: 1-layer, 2-layer, 3-layer, or more (customizable).

• Line Speed: 3–10 meters/minute.

• Applications: Handrails in buses, safety guards, anti-rust bloom sticks, and more.

Process Map:

1. Steel Pipe Pay-Off: Feeds the metal pipe into the coating line.

2. Heating: Preheats the metal pipe for better adhesion of the coating.

3. Dip Glue (Optional): Applies adhesive for enhanced bonding between the metal and plastic layers.

4. Plastic Coating: Extrudes and coats the pipe with plastic layers.

5. Cooling: Cools the coated pipe to stabilize the coating.

Machine Configuration (Simple 3-Layer Coating Machine):

1. Steel Pipe Pay-Off Stand:

• Feeds the metal pipe into the coating line.

2. Haul-Off Unit:

• Pulls the pipe through the coating process at a controlled speed.

3. Oven (High-Frequency Heating Device):

• Preheats the metal pipe to ensure proper adhesion of the plastic coating.

4. 3 Units of Extruder:

• Each extruder applies a different plastic layer (e.g., adhesive, base layer, top layer).

5. Cross Die Head:

• Ensures uniform and precise application of the plastic coating.

6. Water Cooling Tank:

• Cools the coated pipe to stabilize the plastic layers.

7. Haul-Off Unit:

• Pulls the coated pipe through the cooling and finishing stages.

8. Stack Table:

• Collects the finished coated pipes for packaging or further processing.

Applications of Plastic-Coated Steel Pipes:

• Handrails in Buses: Durable and corrosion-resistant.

• Safety Guards: Provides protection with a smooth, coated surface.

• Anti-Rust Bloom Sticks: Prevents rust and extends the lifespan of metal pipes.

• Industrial and Construction Uses: For structural and decorative purposes.

Advantages Of Metal Pipe Plastic Coating Line:

• Customizable Coating: Supports 1-layer, 2-layer, 3-layer, or multi-layer coatings.

• High-Quality Adhesion: Preheating and optional dip glue ensure strong bonding.

• Versatility: Suitable for various plastic materials (PE, PP, PVC, ABS) and metal pipes (steel, aluminum).

• Efficient Cooling: Water cooling tank ensures rapid and uniform cooling of the coated pipes.

The YAOAN Metal Pipe 3-Layer Plastic Coating Extrusion Machine is an ideal solution for industries requiring durable, corrosion-resistant, and aesthetically pleasing coated metal pipes. Its customizable design and efficient operation make it a valuable asset for various applications
