What is the difference between a cylinder and a pressure vessel? Where is the special place
The full name of the new capacity is "the fixed pressure vessel safety technical supervision procedure" Note: the stationary... The cylinders are clearly mobile.
Generalized cylinder should include different pressure, different volume, different structure forms and materials survey to permanent gases, liquefied gas and dissolved gas one-time or repeatable inflatable transportable pressure vessel. The cylinder is a mobile pressure vessel, which is required for the filling unit to be qualified and not to be filled with the expiration cylinders. The safety management of the stationary pressure vessel requires the equipment to manufacture, the operator, the operating procedure and the complete management system.
Because the gas bottle is large, the risk is high
1, the design of the pressure vessel should be designed, and the design qualification seal shall be on the drawing. The design of cylinders shall be subject to the approval of the relevant regulations, and the design shall have the approval mark. The pressure vessel does not do type test, the cylinder is to do the explosion test. The color of the cylinder should be defined by the mandatory national standards.
