Questions about the equipment volume
Thread Content
According to the new version of the fixed-volume regulations, the volume of a device should generally be reduced by the volume of the internals permanently attached inside the container. I would like to ask everyone**, whether the lining inside the container (such as the lining of the medium-temperature converter in a conversion system) also needs to be deducted. Suddenly I’m very stuck on this issue and can’t determine the container category
The lining of the medium-temperature shift converter indeed occupies a considerable volume. I believe that the volume of the lining should be deducted when calculating the container volume.
The lining is a permanently connected structure, so its volume should be deducted. Classifying is easier now!
The interpretation in the Code of Practice states that it is up to the designer to decide whether to take into account the volume of the internal components; failing to do so results in a more conservative classification； Therefore, the capacity regulations stipulate that \"it is generally necessary to consider making a deduction\"” ； A permanent connection generally refers to a connection that can only be removed by destructive means, such as a welded connection.
