I. Characteristics of PSP Steel-Plastic Composite Pipe

1. High Strength and Corrosion Resistance: PSP steel-plastic composite pipe features high strength, corrosion resistance, and deformation resistance, capable of withstanding erosion from various chemical substances, making it suitable for harsh working environments.
2. Excellent Sealing Performance: Utilizes flared ends, dual hot-melt, and press-fit connecting fittings, offering superior sealing performance, resistance to pull-out, and ease of installation.
3. Flexibility and Adaptability: The pipe has a certain degree of flexibility, allowing it to bend and adapt to various complex installation environments. It offers high adaptability for decoration, transportation, installation, and operational reliability.
4. Low Fluid Resistance: The inner wall is smooth, resulting in low fluid resistance, no scaling, and high transmission flow. It can quickly eliminate pressure shocks within the pipeline system without generating water hammer noise.
5. Environmental and Sanitary: The pipe product standards comply with GB/T 17129, making it suitable for transporting drinking water.
6. Long Lifespan and Low Maintenance: The material has a long service life, and the intermediate steel layer is self-traceable, facilitating emergency repairs and maintenance.
7. Good Insulation Performance: The polyethylene material has a high breakdown voltage, and the inner and outer plastic layers offer excellent insulation, making it suitable for applications such as cable protection sleeves.

III. Production Process of PSP Steel-Plastic Composite Pipe

1. Steel Strip Forming: Curled steel strips are formed into a tubular shape using a forming machine.
2. Internal Spray Coating: The tubular product undergoes spray coating to enhance its corrosion resistance.
3. Plastic Extrusion: Plastic material is heated and extruded to coat the outer layer of the steel pipe.
4. Cooling and Cutting: The coated pipe is cooled and then cut to specified lengths.
5. Packaging: The cut pipes are packaged for storage and transportation.
