Calculation of process water tank thickness
Thread Content
The process water tank is designed in accordance with NB-T 47003.1-2009 for welded steel pressure vessels at atmospheric pressure; it operates at atmospheric pressure and 25 degrees Celsius, has an inner diameter of 5800 mm, a height of 10 m, and a liquid level of 9 m. When conducting a water filling test on the water tank, what value should be used for the test pressure during calculations? Is 0.1 MPa used for normal pressure?
The liquid level is 9m at 0.1 MPa; it should be fine, right? It shouldn’t increase by *1.25, right?
The water filling test refers to normal pressure, meaning the top part must be in communication with the atmosphere. It is the pressure test that requires specifying the test pressure.
