Determine whether this filter is a pressure vessel?

This post was last edited by Centrifugal Pump on 2015-10-17 07:51. It is a scraper filter driven by a motor, with a diameter of 275 mm and a height of 1000 mm. The operating pressure is 0.25 MPa, the operating temperature is 134°C, and the medium is a mixture of salt and water. The effective net volume of the container, after deducting the internal components, is 38 L. Is this considered a pressure vessel as defined by regulatory standards? Additional note: Under normal operation, water is in a liquid state.
It should belong to that category; when there is half water inside, the gas phase pressure is 0.25 MPa and the volume is 19 L. This already meets the requirements for a pressure vessel
It should be a pressure vessel. －－－－－－－－－－－－－－－－－－－－－－－－
It is a pressure vessel, it is a pressure vessel, it is a pressure vessel
When in operation the liquid is full, it does not qualify; otherwise, it does.
It can be designed as a pressure vessel, but is not regulated by the Code for Fixed Pressure Vessels.
Is there a gas phase space under normal operation? If so, anything over 10L counts. .
To determine whether a pressure vessel is subject to regulatory controls, it is necessary to check whether the product of its gas volume and pressure is greater than 2.5 Mpa*L. If the pressure is 0.25, then as long as there is a gas volume of 10 L, the vessel falls under regulatory oversight.
If it rotates, the shell part belongs to
It belongs to pressure vessels. And it must be managed in accordance with capacity regulations.
