1. Product Overview
PP water tanks are assembled from polypropylene sheets by hot-air and butt welding, reinforced with PP or steel frames as needed. The material is chemically stable, does not rust and offers good mechanical performance. PP tanks can be designed in rectangular, cylindrical or custom shapes to fit existing spaces in buildings and industrial plants.
- Material: Polypropylene (PP) sheets and profiles, using virgin or specified industrial grades.
- Structure: Welded panel construction with internal/external reinforcement according to tank size and water level.
- Accessories: Manholes, inlets, outlets, vents, level indicator interfaces, overflow and drainage connections.
2. Key Features
Durability & Hygiene
- Corrosion-free operation: PP is resistant to many salts and common water-treatment chemicals, avoiding tank corrosion and metal ion contamination.
- Smooth internal surfaces: Reduce scale and dirt buildup compared with rough concrete surfaces.
- Easy cleaning and maintenance: Flat, weldable surfaces and access openings support regular inspection and cleaning.
Mechanical & Installation Benefits
- Lightweight construction: Lower self-weight reduces structural load on roofs and platforms compared with steel or concrete tanks.
- Good strength when properly designed: Reinforced PP panels can withstand water pressure and typical operating conditions.
- Flexible installation: Tanks can be installed indoors, on roofs, in basements or on outdoor platforms.
Design Flexibility
- Tailor-made capacity: From small buffer tanks to larger equalization or storage tanks, volumes can be designed according to user requirements.
- Space-optimized dimensions: Rectangular or custom shapes make better use of building space compared with standard round tanks.
- Custom nozzles and fittings: Inlets, outlets, overflow, drain and sampling points can be arranged according to system layout.
3. Typical Applications
- Building water storage: Domestic water storage tanks for residential, commercial and public buildings (subject to local regulations and requirements).
- Process and industrial water: Storage of process water, cooling water, recycled water and rinse water in factories and workshops.
- Wastewater treatment: Equalization tanks, collection tanks and buffer tanks in small treatment systems and pretreatment units.
- Circulation and utility water: Tanks for fire-fighting reserve water, irrigation water and general utility water.
- Other compatible liquids: Storage of certain chemical solutions and auxiliary media after chemical compatibility evaluation.
