Overflow Pipe for Water Circulation and Cooling Tank

The overflow pipe is a critical auxiliary component that ensures the safe operation of the tank and the stability of water quality. Typically installed at the top or a pre-set high position of the water circulation tank, it connects to the inner cavity of the tank at one end and leads to a drainage system or recovery device at the other, serving to promptly discharge water that exceeds the safe liquid level inside the tank.

The overflow pipe requires no complex power units or control systems; it achieves automatic drainage solely through liquid level differences. With a low failure rate, its maintenance costs are nearly negligible. Even in the event of system power outages or automatic control failures, it remains effective as a protective measure, acting as the “last line of defense” for tank safety.

The pipe’s diameter, material (such as stainless steel or PVC), and installation angle can be designed based on the water circulation tank’s capacity and operational requirements (e.g., maximum water return volume, liquid level fluctuation range). This allows it to adapt to corrosion resistance or sanitary grade requirements across various industries (chemical, food, metallurgy, etc.) and enables easy integration with existing drainage systems—providing low-cost assurance for system stability.
