Does a filtration tank count as a pressure vessel?
Thread Content
The sand filter tank has a diameter of 3 meters, a height of about 4 meters, and an operating pressure of 1.1 MPa. Is it considered a pressure vessel? Is it subject to regulation? Is a license required for its manufacture?
If the filtration tank operates at a pressure exceeding 0.1 MPa, based on the parameters you provided, it falls under the category of pressure vessels according to **relevant regulations**; it is subject to supervision, and manufacturing it requires an appropriate license. .
It depends on the pressure, volume, and the medium being contained
It should not be considered a pressure vessel. The main sand filters are used to filter water only; there is no air. Also, why is the internal pressure in your sand filters so high? Could there be a mistake?
It is not considered a pressure vessel; pressure vessels must meet three conditions； 1. Working pressure is greater than or equal to 0.1 Mpa ； 2 containers greater than 0.03 and with a diameter of 150 mm or more ； The filling medium is gas, liquefied gas, or a liquid whose maximum operating temperature is higher than or equal to its standard boiling point ；
No, the medium is water. Even a pressure of 10 MPa doesn’t count.
