designing pressure chamber 3

[200984]

hello..i need to design a pressure chamber for my project, which can stand 100 psi pressure, but i dont know what type of chamber should i use for that pressure, and how to connect the nitrogen gas supply to it..can anyone help me..

200984,
The pressure chamber you mentioned is a pressure vessel and the design of it is subject of compliance with a recognized design code or standard, like ASME Boiler and Pressure Vessel Code, Australian Standard 1210, European Norm 13445, etc...A good start would be to investigate and clarify for yourself what is the object you called 'pressure chamber', where is that thing going to be installed, then start reading the definition of a pressure vessel. The size of your chamber is critically important, also the location;- is it located on the bottom of the ocean or is floating 250 miles above the earth, hope is not a gas chamber...
You are a bioengineer, aren't you?
Cheers,

dear gr2vessels :

thanks for ur reply..im really appreciate ur cooperation..
this pressurized chamber will be assemble to high performance liquid chromatography (HPLC) system as the post reactor column..
i did some readings but couldn't find the exact answer especially for nitrogen gas fitting.

Please take my advice;- the design of this equipment requires an experienced pressure vessel designer and the use of a specialised design software like Compress or PV Elite, if designed to the ASME VIII Div 1 code. There are also other codes and associated software in the world for your choice.
I don't believe that you should do this design, due to the potential safety problems associated with this equipment of which you obviously are not aware / competent.
Please ask a competent pressure vessel designer, including the accredited fabricator to help you out with this job.
Best of luck,

I suspect that the term 'pressure vessel' applies, but not in the sense it might inferred.

No dimensions are given, but the reference to HPLC probably means a volume in the range of several milliliters at 100psig, which commercial stainless tubing should handle.

For a summer job in the late 1970's, I hand packed HPLC columns made from 1/8" or 1/4" OD SS tubing. We connected the column to tubing with appropriate off-the-shelf, commercial SS Swagelock or Parker compression fittings.

The lab supplied the SS tubing for the column and plumbing, I presume it was rated for column pressure.

Compression fitting components (ferrules/nuts) should never be mixed between brands.

dear gr2vessels & danw2

thank u so much for ur valuable advices..
im really hope i can settle this as soon as possible..

could be mistaken but the codes have minimum volume restrictions i.e they do not apply
