PP & HDPE Tanks and Reservoirs
PP (Polypropylene) and HDPE (High-Density Polyethylene) tanks and reservoirs are advanced thermoplastic storage solutions designed for water, wastewater, and chemical containment. They provide excellent corrosion resistance and long service life, making them ideal alternatives to steel or concrete tanks.
1) PP (Polypropylene) Tanks
Description:
Manufactured from high-quality polypropylene sheets using extrusion welding technology, PP tanks are known for their rigidity and strong resistance to chemicals and higher temperatures.
Key Features:
- Excellent chemical resistance
- Higher temperature resistance compared to HDPE
- High structural strength
- Smooth internal surfaces
- Custom fabrication available
Applications:
- Chemical storage tanks
- Industrial process tanks
- Dosing and mixing tanks
- Laboratory and plating tanks
Best For:
Applications involving aggressive chemicals and elevated temperatures.
2) HDPE (High-Density Polyethylene) Tanks
Description:
HDPE tanks are produced using rotational molding or fabrication welding methods. They offer superior flexibility and impact resistance, making them suitable for large-capacity storage and outdoor installations.
Key Features:
- Outstanding impact resistance
- Excellent UV resistance (with UV-stabilized grades)
- High flexibility
- Lightweight and easy installation
- Long service life
Applications:
- Potable water storage
- Wastewater tanks
- Rainwater harvesting reservoirs
- Irrigation storage systems
Best For:
Large-volume storage and outdoor environments.
