The standard of the gas storage capacity of the oxygen cylinder is the pressure resistance.
The upper limit of the pressure of a conventional oxygen cylinder is 15Mp (megapascal), which is 147 atmospheres when converted to atmospheric pressure.
The test value of withstand voltage capability is 22.5Mp.
The internal pressure of conventionally filled cylinders should be around 12~15Mp.
The gas in the bottle cannot be completely used up, and the residual pressure of not less than 0.1-0.2MP should be retained.
