The 315PVC pipe extrusion line is a complete manufacturing solution designed for high-volume production of PVC pipes up to 315mm in diameter. Engineered by Zhangjiagang Qinxiang Machinery, this line integrates advanced extrusion technology, precise control systems, and durable components to ensure consistent pipe quality, minimal waste, and low operating costs. Ideal for PVC pipe production lines, this equipment supports both rigid (PVC-U) and modified (PVC-M) grades, making it a versatile choice for manufacturers.






High Output & Efficiency
Production capacity ranges from 300 to 650 kg/h, ensuring rapid throughput for large-scale orders.
Energy-Optimized Design
Total installed power is 160 kW, with ABB变频器 and Siemens PLC for precise energy management, reducing electricity costs.
Multi-Material Flexibility
Handles virgin PVC, recycled materials, and high calcium carbonate content (up to 80 phr), lowering raw material expenses.
Precision Extrusion
The SJSZ80/156 conical twin-screw extruder features a nitrided screw/barrel (38CrMoAlA) with hardness 800–900 HV, ensuring long service life and melt uniformity.
Fully Integrated Downstream Equipment
Includes an 8m vacuum calibration tank, servo-driven 4-track caterpillar haul-off, ring chipless cutter with chamfering, and an automatic belling machine (R & U socket types).
The line is built for PVC pipe production with:
Wear-resistant screws (Zhoushan Jinjiu brand)
Stainless steel vacuum tanks (5mm thickness, dual water circuits)
Mold flow channels hard chrome-plated (0.03–0.05mm) for low friction
Cloud insulation heaters to reduce heat loss
The process ensures pipes meet GB/T 10002.1 standards for pressure ratings PN0.63, PN0.8, and PN1.0.
The 315mm PVC pipe extrusion line is trusted across multiple industries:
