PVC-O pipe, whose Chinese name is biaxially oriented polyvinyl chloride pipe, is the latest evolutionary form of PVC pipe. It is manufactured through a special orientation processing process. The PVC-U pipe produced by the extrusion method is stretched axially and radially, so that the PVC long-chain molecules in the pipe are regularly arranged in the biaxial direction, thereby obtaining a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.
Main features
- High strength and high toughness: Through the biaxial stretching process, the molecular structure of PVC-O pipe is more regular, which significantly improves its strength and toughness, allowing it to perform well in high-pressure environments.
- Impact resistance and fatigue resistance: PVC-O pipe has excellent impact resistance and fatigue resistance, and is suitable for long-term use in harsh environments.
- Thin-wall design: Due to molecular orientation processing, the wall thickness of PVC-O pipes is thinner, saving 35%-40% of material than traditional PVC-U pipes and reducing costs.
- Environmental protection and sustainability: The production process of PVC-O pipe reduces material consumption and meets the requirements of sustainable development.
PVC-O pipes are widely used in the following fields:
- Urban Water Supply: Due to its high strength and pressure resistance, PVC-O pipe is ideal for urban water supply systems.
- Farm Irrigation: PVC-O pipe performs well in high-pressure water transportation and harsh environments.
- Pipe for Mining: The high impact resistance of PVC-O pipe makes it suitable for special fields such as mining.
- Trenchless laying and repair: PVC-O pipe has significant advantages in trenchless laying and repair projects.
Production process The production process of PVC-O pipe mainly includes two steps:
Extrusion molding: PVC-U pipes are first produced by extrusion method. Biaxial stretching: axial and radial stretching of PVC-U pipes, so that the molecules are regularly arranged in the biaxial direction to form high-performance PVC-O pipes. Summarize As a high-performance plastic pipe, PVC-O pipe has significantly improved its physical properties through special orientation processing technology. It is widely used in urban water supply, farmland irrigation, mining pipes and other fields. Its high strength, high toughness, impact resistance and fatigue resistance make it an important choice in modern pipeline engineering.
