Is a high-pressure switch tank a pressure vessel
Pressure vessel manufacturing is very strict operation and operation of internal pressure, full of toxic gas, in the event of accident, consequences, especially on the sealing performance of pressure vessel, pressure load capacity requirements strictly!!!!! So it is very strict in manufacturing operation!!
You give too little, you control yourself, if you do, the pressure vessel.
According to the state council in 2009, no. 549 "special equipment supervision regulations" regulation: pressure vessel, refers to holding gas or liquid, carrying a certain pressure airtight device, the range of maximum working pressure is greater than or equal to 0.1 MPa (table), and the product of the pressure and volume of greater than or equal to 2.5 MPa, L gas, liquefied gas and the highest standard of working temperature is higher than or equal to the boiling point of the mobile and stationary containers of liquid container; All nominal working pressure is greater than or equal to 0.2 MPa pressure (table), and the product of the pressure and volume greater than or equal to 1.0 MPa, L standard of gas, liquefied gas, and the boiling point is equal to or lower than 60 ℃ liquid cylinders; Oxygen tank, etc.
