PVC pipe production line / double outlet extrusion system / 16–90mm range: A newly introduced 16–90mm double-outlet PVC pipe production line has been presented for continuous manufacturing of PVC pipes. The system is designed to support stable extrusion, sizing, cooling, and cutting processes, enabling efficient production of multi-diameter PVC pipes for construction, municipal engineering, and agricultural applications.
Equipment Overview
PVC pipe manufacturing system / application scope: The production line is used for continuous extrusion of PVC pipes across a wide range of diameters and wall thicknesses. Through heating, plasticizing, extrusion, and shaping, PVC raw materials are processed into standardized pipe products suitable for industrial use.
Double-outlet design / productivity improvement: The system adopts a double-outlet configuration, allowing simultaneous extrusion of two pipe streams. This structure is intended to increase output efficiency and support continuous, large-scale production requirements.
Main System Configuration
Twin-screw extrusion unit / core processing system: The production line is equipped with a double screw extruder, which ensures uniform mixing and melting of PVC materials and additives before extrusion through the die head.
Forming and cooling section / vacuum sizing process: A die head, vacuum sizing tank, and spray cooling tank are integrated to stabilize pipe dimensions. The vacuum system ensures accurate shaping, while water cooling supports rapid solidification.
Haul-off and cutting system / automated downstream handling: The line includes a traction unit, cutting machine, and stacking system. The haul-off device ensures stable pipe pulling, while the cutter performs precise fixed-length cutting.
Applicable Pipe Types and Applications
PVC-U pipes / construction and municipal use: The system supports production of PVC-U water supply and drainage pipes, widely used in building drainage and municipal water systems due to their corrosion resistance and mechanical strength.
Electrical conduit pipes / cable protection systems: It can produce PVC conduit pipes used for electrical and communication cable protection in underground installations.
Agricultural irrigation pipes / farming infrastructure: The system is suitable for manufacturing irrigation pipes used in agricultural water distribution systems.
CPVC applications / extended high-performance uses: In extended applications, CPVC pipes can be used for heat-resistant, corrosion-resistant pipelines, including industrial fluid transport and power cable protection.
Production Process Flow
Raw material preparation / mixing stage: PVC resin is blended with stabilizers and processing additives in controlled proportions to ensure uniform material properties.
Extrusion forming / melting and shaping process: The mixed material is fed into the twin-screw extruder, where it is heated, plasticized, and extruded through the die head to form pipe blanks.
Vacuum sizing and cooling / dimensional stabilization: The pipe enters a vacuum calibration tank, where negative pressure ensures dimensional accuracy, followed by water spray cooling for rapid shaping.
Haul-off and cutting / continuous production stage: A traction system pulls the pipe steadily through the line, while an automatic cutter performs fixed-length cutting to produce finished sections.
System Features
Variable frequency control / stable operation performance: Key drive systems adopt variable frequency or DC speed control to ensure stable and adjustable production speed.
Flexible haul-off configurations / adaptable pipe sizes: Depending on pipe diameter and wall thickness, the haul-off unit can be configured with multi-caterpillar, three-claw, four-claw, or six-claw systems.
Optional cutting methods / production flexibility: The cutting unit supports both saw blade cutting and planetary cutting systems, equipped with length measurement devices for precise control.
