Square Stainless Steel Water Tank SS304 SS316L Metal Water Storage Tanks

Square Stainless Steel Water Tank

Product Overview

The Stainless Steel Water Tank is a high-quality storage container designed for storing potable water, purified water, and process water in various applications.
It is manufactured from premium-grade stainless steel (SS304 or SS316L), ensuring excellent corrosion resistance, hygiene, and structural integrity.

Working Principle

The stainless steel water tank functions as a buffer and storage unit in water treatment or supply systems.
Raw or treated water enters the tank through the inlet pipe, and the stored water is then distributed through the outlet under controlled pressure.
The vent filter maintains internal air balance while preventing contaminants from entering, ensuring that the water remains clean and safe.
The tank can be integrated with level sensors, pumps, and control systems for automatic water level regulation and real-time monitoring.
