Factor Of Safety for Pressure Vessels (Blow Tanks or Air Receiver Tanks)

Dear All,

I have come across 'factory of safety' as a parameter in calculating thickness of pressure vessels as a part of my study project. How is it calculated?

Thanks in advance,

Vandana

Dear vandana,

The calculation of a pressure vessel has to be executed according the governing rules.

As input, apart from the pressure, the temperatures are considered and (very important) the number of pressure changes during its lifetime.

The used rules also mention the testpressure.

In addition, the rules are specific about the regular pressure tests during the lifetime of the pressure vessel.

Following the rules automatically accounts for safety factors.

have a nice day

There is no such thing as a factor of safety for pressure vessels. These are designed according to a strict legally regulated and enforcable set of codes. You are heading for serious trouble, possible jail in Europe, if you do not employ a competent pressure vessel designer, appoint an AI (Authorised Inspector) and select a fabricator licenced to do the manufacture and testing. Such are your legal obligations in any land. I now consider my legal professional obligation to be discharged in this situation.

The legal ISO unit of pressure is the Pascal by the way.
