Introduction of PVC Double and Four Pipe Machine: 
PVC Double and Four Pipe Production Line is specially designed for producing PVC pipe. It mainly includes twin screw extruder, pipe extrusion die, vacuum calibrating water tank, spray cooling water tank, hauling unit, cutting unit and stack unit. PVC pipe is widely used in the machinery, coal mine, oil, chemical liquid, agriculture irrigation, gas and building.

Features of this PVC Pipe Extrusion Line: 
1. Conical twin screw extruder: Advanced and unique screw design concept ensures the high efficiency extrusion of PVC material, Unique screw design combined with plasticization concept ensures flexible plasticization and super-high output extrusion, Advanced control system ensures the good running.
2. PVC extrusion die: innovative spiral flowing structure avoids fuse mark appearance on the bigger pipe, profile of ideal dwell time is full of the whole flow cross-section, Homogeneous melt distribution with selective temperature control guarantees outstanding product characteristics for PVC materials.
3. Vacuum calibration water tank: with visible stainless steel structure, With two-stage vacuum system in vacuum calibration tank for large diameter pipe, With accurate water level & water temperature automatic control system, With stable recycle liquid filter system.
4. Spray cooling water tank: special spray ensure fast cooling effect, stainless steel effects environmental concept, With accurate water level & water temperature automatic control system with advanced valve& element.
5. Hauling unit: Separate speed regulation and flexible hauling method, high-reliable transmission system ensures the high efficiency and high quality normal extrusion. Special integral transmission unit avoids asynchrony of individual transmission, Advanced four connecting rod structure makes self-centering of haul-off's locating, accurate pressure regulating system makes hauling power adjustable.
6. Cutting unit: Full-hydraulic design ensures flexible pressure in cutting state of pipes, Unique power input system ensures high reliability of planetary unit, With ultra silent & enforced sucking system, auto angle chamfer function.
