Does a jack qualify as a pressure vessel?
Thread Content
Large-tonnage hydraulic jacks are widely used in various industries. During operation, the internal pressure is 70 Mpa, and the fluid used is hydraulic oil type 46. Should they be classified as pressure vessels?
It does not belong; there should be separate regulatory requirements.
It is not a pressure vessel; it may meet the requirements for both maximum operating pressure and volume, but its maximum operating temperature is below the boiling point of hydraulic oil No. 46.
Take a look to see if these are what you need; I’m not entirely sure either.

Tools and equipment do not fall under the category of pressure vessels
It shouldn’t belong here; this isn’t a container, is it?
