I. Characteristics of PSP Steel-Plastic Composite Pipe

1. Corrosion Resistance: PSP steel-plastic composite pipe features high strength and corrosion resistance, enabling it to withstand erosion from various chemical substances, making it suitable for harsh working environments.
2. Excellent Sealing: Utilizing flared ends, dual hot-melt, and press-fit connections, it offers superior sealing performance, anti-pullout capability, and easy installation.
3. Good Flexibility: The pipe has a certain degree of flexibility, allowing it to bend and adapt to various complex installation environments, with high adaptability in decoration, transportation, installation, and operational reliability.
4. Smooth Inner Wall: The inner wall is smooth, resulting in low fluid resistance, no scaling, high transmission flow, rapid elimination of pressure shocks within the pipeline system, and no water hammer noise.
5. Environmental and Sanitary: The pipe product standards comply with GB/T 17129, making it suitable for potable water transmission.
6. Long Service Life: The material has a long lifespan, 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 conduits.

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 Coating: The tubular product is coated to enhance its corrosion resistance.
3. Plastic Extrusion: Plastic material is heated and extruded to cover 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.

IV. Application Fields of PSP Steel-Plastic Composite Pipe

1. High-Rise Building Water Supply and Drainage: Suitable for water supply and drainage systems in high-rise buildings.
2. Water Supply Enterprises: Used as water transmission pipelines, featuring high pressure resistance and corrosion resistance.
3. Industrial Sector: Used in oil, chemical, metallurgy, and other industries for oil and gas transmission, storage systems, etc.
4. Municipal Sector: Applied in water supply, drainage, air shafts, street lamps, and other pipeline systems.
5. Construction Sector: Suitable for heating, air conditioning, drainage, and other pipeline systems.
6. Agricultural Sector: Used in irrigation, drainage, fertilizer transmission, and other pipeline systems.
