PPR pipes are widely used for cooling water systems in industries due to their corrosion resistance, smooth internal surface, and long service life.
Advantages of PPR for Cooling Water Systems
Corrosion-free: Unlike metal pipes, PPR does not rust or scale, maintaining consistent flow rates.
Low pressure loss: Smooth internal walls reduce friction and pumping energy consumption.
Chemical resistance: Suitable for treated cooling water and many industrial water applications.
Long service life: Typically designed for more than 50 years under recommended operating conditions.
Leak-proof joints: Heat fusion welding creates homogeneous joints with minimal leakage risk.
Lightweight and easy installation: Reduces installation time and labor costs.
Typical Applications
Cooling tower water circulation
Chilled water distribution systems
HVAC cooling networks
Process cooling water lines in manufacturing plants
Return and supply lines for industrial cooling systems
Recommended PPR Types
PPR PN16: Suitable for low-pressure cooling water applications.
PPR PN20: Common choice for industrial cooling water distribution.
PPR PN25 (fiber or glass reinforced): Preferred for higher pressures and temperatures with reduced thermal expansion.
Design Considerations
Provide adequate support spacing for pipes.
Include expansion loops or compensators for long pipe runs.
Use UV protection if pipes are installed outdoors.
Verify operating temperature and pressure are within pipe ratings.
For most industrial cooling water systems operating below 70°C, reinforced PN20 or PN25 PPR pipes are commonly recommended for reliable long-term performance.
