PVC Pipe Plant Screw Barrel

About PVC Pipe Plant Screw Barrel

The PVC Pipe Plant Screw Barrel is a high-performance and precision-engineered component used in PVC pipe extrusion lines for processing rigid PVC (uPVC), CPVC, and other PVC-based compounds. It plays a vital role in conveying, compressing, melting, mixing, and homogenizing raw materials to ensure consistent melt quality and high production efficiency.

Manufactured from premium-grade alloy steel and processed through advanced nitriding and heat treatment technologies, the screw barrel is designed to withstand high temperatures, pressure, abrasion, and corrosion commonly encountered during PVC processing. Its optimized screw design ensures efficient plasticization, uniform material flow, and superior pipe quality.
