UPVC pipes are known for their strength, chemical resistance, and durability, making them suitable for both residential and industrial use.

Technical Specifications Aquadex Dadex upvc Pressure pipe 8″

Key Features

1. Corrosion Resistance – Immune to rust and chemical scaling
2. Smooth Interior – Low friction, minimizing pressure losses
3. Lightweight – Easier handling and installation than metal pipes
4. Long Lifespan – 50+ years under normal conditions
5. Thermal Insulation – Better than metal pipes for hot water systems

Installation Guidelines

Pre-Installation

• Inspect pipes for cracks, chips, or deformations.
• Store Pipes in a shaded, flat area to avoid UV degradation.

Joining Methods

1. Solvent Cement Welding (Most Common):

   • Cut pipe square, bevel edges.
   • Clean and apply UPVC primer and cement.
   • Join immediately and hold for 30 seconds.

2. Threaded Connection:

   • Use thread-seal tape or compound.
   • Do not over-tighten to avoid cracking.

3. Flanged Connection:

   • Use proper gaskets (usually EPDM or Viton for hot water).

Testing

• Perform a hydrostatic pressure test (1.5x working pressure) before covering.
• Check for leaks at joints and connections.

Usage in HVAC & Water Supply

HVAC Applications

• Chilled Water Systems – Ideal for AC condensate and chilled water lines.
• Cooling Tower Piping – Suitable for open-loop systems with proper chemical treatment.
• Heat Pump Systems – For indoor/outdoor unit connections.

Hot & Cold Water Supply

• Domestic Hot Water (DHW) – Up to 60°C (with de-rating for higher temperatures).
• Cold Water Mains – Excellent for potable water distribution.
• Irrigation – Suitable for pressurized agricultural systems.
