PVC UPVC CPVC Pipe Making Machine

In the rapidly expanding global construction and industrial infrastructure market of 2026, high-quality U-PVC (Unplasticized PVC) and C-PVC (Chlorinated PVC) pipes, manufactured by advanced PVC UPVC CPVC pipe making machine, have become the cornerstones of modern piping systems. Leveraging 15 years of technical expertise, Kangju Machinery provides fully automated PVC pipe extrusion line that integrates efficiency, energy savings, and intelligent control.

PVC UPVC CPVC Pipe Making Machine

This UPVC CPVC pipe making machine is specifically engineered to meet the high rigidity requirements of U-PVC and the challenging heat-sensitive processing of C-PVC, covering a comprehensive production range from 16mm to 630mm.

UPVC CPVC Pipe Extrusion Line

Advanced Extrusion System: Conical Twin-Screw Technology

To address the characteristics of direct PVC powder molding, we utilize a high-torque conical twin-screw extruder:

  • Forced Conveying Capability: The tapered design, with a large feeding end and small discharge end, provides excellent material shear distribution and high-pressure extrusion.
  • Bimetallic Screw & Barrel: Surface-treated with a special tungsten carbide alloy, extending the service life by 3–5 times compared to standard nitrided screws—ideal for high-filler CaCO3 formulas.
  • Precision Thermal Management: Equipped with air-cooling for the barrel and an internal oil-circulation system for the screw core. Temperature accuracy is maintained within ±1℃, solving the critical issue of material degradation in C-PVC.

Heavy-Duty Downstream for Industrial Standards

U-PVC and C-PVC pipes for industrial pressure applications must meet strict ASTM or DIN standards. Kangju’s downstream equipment is built for this rigor:

  • Vacuum Calibration Tanks: Extended length and high-efficiency spray nozzles ensure that thick-walled pressure pipes are cooled evenly to avoid internal stress.
  • Planetary Cutting Machines: For large-diameter U-PVC pipes, our planetary cutters provide a clean, chamfered edge, which is essential for solvent-cement jointing or rubber-ring socketing.

Automated Socketing (Belling) Solutions

The final step in a professional line is the automatic belling machine. Whether you need “U” type (solvent weld) or “R” type (rubber ring) sockets, our online belling units deliver. They utilize infrared heating for uniform softening, ensuring maximum joint strength.

FAQ:

Q: Can I use the same machine for both U-PVC and C-PVC production?

A: The basic machine structure is similar for both. However, C-PVC requires a more powerful motor and a specialized screw and barrel. This is primarily because C-PVC has a much higher viscosity during processing.

Q: What is the typical scrap rate for Kangju PVC pipe production line?

A: With our precision dosing and synchronized haul-off systems, the scrap rate during stable production is typically below 1%.

Q: How many hours can the machine run before requiring a screw cleaning?

A: Our optimized flow designs allow for continuous 24/7 production. Depending on your stabilizer package, our lines can typically run for 3–4 weeks without requiring a manual teardown for cleaning.

Q: Does Kangju provide the chemical formulas for PVC?

A: Yes. We provide tested starter formulas for various pipe grades. This helps our clients balance raw material costs with the physical requirements of their target market.
