How Big, How Thick, How Strong?

Guidelines for vacuum vessel

design at ANSTO

Microprobe Chamber Design

But isn't this a

vacuum vessel not a

pressure vessel?

According to AS1210-2010

If all vacuum vessels fall under AS1210 for design,

what does this mean for us?

According to AS4343-2005

• Almost all vacuum equipment used at ANSTO

are Hazard Level E

Vacuum vessels of internal volume ≤3000L

Hazard Level E – No specific regulatory controls.

Limitations to the guide

For more complex designs:

- Non – cylindrical

- Large penetrations

- Larger than 300 Litres

The Pressure Vessel Approvals Officer Should be

consulted during the design process.
