Online request for help: Do water treatment filters fall under the category of pressure vessels? Are there any relevant standards or specifications that provide specific guidelines on this?
Whether a water treatment filter is considered a pressure vessel depends on its design pressure and operating conditions. According to the definition in the \"Regulations on Safety Inspection of Pressure Vessels,\" a pressure vessel refers to a closed vessel whose operating pressure is greater than or equal to 0.1 MPa (gauge pressure). If a water treatment filter operates at a pressure that reaches or exceeds this standard and is of a closed type, then it is considered a pressure vessel. To determine whether it constitutes a pressure vessel, it is recommended to consult relevant professionals or check the equipment’s instructions and markings. .
No, the medium is water; even at a pressure of 100 MPa, it’s not possible
As I understand it, this means the design pressure is greater than 0.1, and the inner diameter is greater than 150； So it is a pressure vessel ； If the medium is liquid water, then it does not fall under the category of special equipment ；
That’s inaccurate; the medium should be a gas, a liquefied gas, or a liquid whose operating temperature is above its boiling point. Normal water does not fall under the category of pressure vessels
Those with a pressure greater than 0.1 MPa all fall under the category of pressure vessels
