What are criterea for calculating the thickness of ammonia high pressure receiver shell and dishend.


Is only consider ASME code.

Or storage capacity of ammonia / flow of ammonia / persons working there. Ammount of ammonia charge.

... not too familiar with ASME codes, but I believe they covered everything....

... many years before I was working in factory manufactured pressure vessels and this is something I can remember now ...

.... mainly thicknesses depend on many factors like .... pressure "P", diameter "D", volume "V", size and number of connections, material properties-different for normal or low temperatures application... there are a special equitations for calculation of static vessels .....

... then we have requirements for manufacturer certification, quality assurance, design, materials, manufacturing and testing ....

.... not a simple manufacture procedure at all...

Best regards, Josip :)

There is one book on heat exchanger design & that gives all the data. I shall get that name for you.

Yes ASME is the code.
The temp/press is considered.
To do these calculations by hand I used to be able to do 1/10 hr day.
With Software...I did 5 before lunch depending on the openings.
Codeware and many more are availeable Cost ..about $5-6k
But what is time worth?

You need to design the vessel for what you want it to do. Size, volume, nozzles, etc. Once you have the geometry of the vessel, then you use the pressure vessel codes to design the thickness, welds, heads, etc.

These are two separate design procedures.
