PVC-O Pipe Extrusion Line – Advanced Biaxially Oriented PVC Pipe Manufacturing Solution

The PVC-O Pipe Extrusion Line from GRACE is an advanced production system designed for manufacturing high-performance PVC-O (Biaxially Oriented PVC) pipes with superior strength, toughness, impact resistance, and long-term durability. Using innovative air-based in-line orientation technology, the system transforms conventional PVC-U pipes into highly engineered pressure pipes through controlled axial and radial molecular orientation.

PVC-O pipes offer outstanding mechanical performance compared with traditional PVC-U pipes, making them ideal for demanding applications such as high-pressure water supply, mining, irrigation, drainage, sewage, and gas distribution networks.

What is PVC-O Pipe?

PVC-O pipe is produced from PVC-U pipe through a special orientation process that stretches the pipe in both axial and radial directions. This biaxial stretching reorganizes polymer molecules into an ordered mesh structure, significantly improving the pipe’s mechanical properties.
