Pipeline installation method between the storage tank outlet and the pump
Thread Content
The elevation of the tank outlet is 500 mm, and the elevation of the pump inlet is also 500 mm. The elevation of the tank cofferdam is 1800 mm. Does the pipeline at the tank outlet connect to the pump inlet by passing through the cofferdam, or does it connect after going over the cofferdam? ?
Neither is good: the outlet elevation is consistent, there is no space for elbows or valves, and material accumulation is severe. First, increase the outlet height of the equipment or reduce the pump’s outlet height by lowering the level, so as to connect it to the cofferdam.
Pass through the enclosure, and the pump operates in a separate small cofferdam
There are special requirements for pipes passing through the cofferdam, which need to be taken into account. Also, do not connect the pump by yourself; instead, make a U-turn in the pipe
It is possible to pass straight through the cofferdam; there is no requirement to cross it. However, the area where the cofferdam is installed requires special treatment to ensure proper sealing.
