We provide a comprehensive range of plastic pipe production lines, including 16-630mm PVC/UPVC pipe lines, 16-1200mm HDPE pipe lines, as well as lines for PP/PPR pipes, HDPE/PP/PVC double-wall corrugated pipes, and single-wall corrugated pipes. These production lines are designed to manufacture pipes for various applications including water supply, drainage, gas supply, and conduit wiring.

The PVC pipe production line specifically manufactures PVC pipes of different diameters and wall thicknesses, widely used in agricultural water supply, drainage, and electrical conduits.

The UPVC pipes produced by this line find extensive use in both industrial and daily scenarios, including:

• Electrical conduits
• Water supply pipes
• Sewage pipes
• Home decoration
• Chemical transportation
• Gas distribution lines

These pipes boast high strength and rigidity, structural integrity, excellent chemical resistance, durability, thermal stability, non-toxic safety, low maintenance needs, and cost-effectiveness.

PVC powder + additives → Mixing → Spring feeding → Twin-screw extruder → Mould and calibrator → Vacuum forming machine → Haul-off machine → Cutting machine → Stacker.

Boasting a specialized design, the mixer reduces raw material self-friction, which enhances energy utilization efficiency. Equipped with a vacuum suction loading system, it operates with low noise and maintains a dust-free working environment.

Crafted with top-brand components, the extruder ensures stable production, high efficiency, and long-term durability. Its conical twin-screw design is tailored to raw material characteristics, enabling homogeneous mixing, superior plastification, and efficient conveying.

The vacuum calibration tank features a two-chamber structure, integrating vacuum calibration and cooling functions. Both the vacuum tank and spraying cooling tank are made of 304 stainless steel. The high-performance vacuum system guarantees precise pipe sizing.

Equipped with three crawler track belts, the haul-off machine ensures stable movement of produced pipes. By adjusting the general control, it can be customized into tailored hauling modes to meet specific production requirements.

A high-precision encoder ensures accurate and stable cutting lengths. Controlled by a PLC system, it supports manual operation for cutting according to specific application needs.
