⚙️ Description
- Aquadex Dadex is Pakistan’s premier uPVC pressure piping system, bridging both ASTM (inch-based) and BS (metric-based) standards.
- Pipes are non-corrosive, lightweight, and durable, ensuring long service life compared to metal alternatives.
- Manufactured with smooth internal surfaces to minimize friction losses in water flow.
- Resistant to chemical attack, scaling, and biological growth, making them ideal for potable water.
🚰 Usage Applications
- Water Supply: Municipal distribution, residential plumbing, and commercial water systems.

- Industrial Use: Factories, chemical plants, and cooling water lines.
- High-Rise Buildings: Vertical risers for water distribution.
- Underground Installations: Sewerage and pressure water mains.
⚠️ Key Considerations & Limitations
- Temperature Sensitivity: Pressure rating decreases at higher temperatures (e.g., at 40°C, derating factor ~0.62).
- Threading: Not recommended for Schedule 40; use solvent cement joints instead.
- Pressure Class: Ensure correct sizing for pumps and municipal supply to avoid overloading.
