Classification methods for pressure vessels
Thread Content
Which expert can explain the classification charts for the first and second groups of media? Are there no Class I pressure vessels among the first group of media?
The regulations are quite clear: the first category includes media with extreme or high toxicity, flammable media, and liquefied gases. The second group of media is those other than the first group of media. Container classification as per the diagram. There are no Class I containers on the first group of medium classification diagrams; in other words, such media do not have Class I containers.
Then how should containers with a pressure of less than 0.1 MPa and a volume of less than 0.03 m3 in the first group be classified?
