For a jacketed filter like this, if steam is used for heating the jacket, does it then become a pressure vessel?
Those with steam constantly coming in and going out do not qualify; those whose pressure does not reach 0.1 MPa, as well as those whose volume is less than 0.3 m3, also do not qualify.
By examining the operating pressure of the steam and the volume of the jacket, if it meets the requirements of the Fixed Volume Regulations, it is considered a regulated pressure vessel.
For work conditions with a pressure of up to 4 kilograms like this, pressure vessels are not designed
Reason 1: The equipment features a quick-opening structure; the design pressure specified by the manufacturer for this structure is 0.6 MPa. Reason 2: The equipment has a lining
A quick-opening structure and lining cannot constitute a condition for something to not be considered a pressure vessel, right? Whether it is a pressure vessel subject to regulatory requirements should still be determined in accordance with the regulations for pressure vessels.
3 conditions: Working pressure (PW) ≥ 0.1 MPa (excluding hydrostatic pressure)； Inner diameter (for non-circular cross-sections, the maximum dimension) ≥ 0.15M and volume V ≥ 0.025M3 ； The filling medium is a gas, a liquefied gas, or a liquid whose maximum operating temperature is greater than or equal to its standard boiling point.
On top of that, there are very few manufacturers who actually possess the necessary certificates; moreover, the prices are exorbitant. Those who do have the required qualifications purchase the products from others and then sell them under their own name
The volume is 30L or greater.
