material selection for pressure vessel

material selection for pressure vessel

material selection for pressure vessel

(OP)
I'm working on making a pressure vessel that will be exposed to Argon, CO2, air, Helium, and nitrogen. I was wondering if anyone could point me in the right direction for references or standards regarding the material selection of such a system.

RE: material selection for pressure vessel

Any water? Concentration of CO2? Temperature? Pressure?

RE: material selection for pressure vessel

(OP)
Yeah sorry I guess this should have been made clear. Only gas will be present. The temperature will notexceed 40 degrees celcius. The pressure will be around 100 atm or 1500 psi.

RE: material selection for pressure vessel

(OP)
The concentration of C02 will be anywhere from 0%-100%

RE: material selection for pressure vessel

How big might it be?

RE: material selection for pressure vessel

(OP)
The pressure vessel will be no larger than 18" in Diameter but no smaller than 8" in diameter. It will be a cylinder vessel with flanges on each end. The cylinder will be no longer than 24" but no shorter than 12".

We are in the design process right now so the instrumentation and sample size (samples we will put in the chamber to test) will determine the size of the vessel. I hope the range I gave will be helpful enough.

RE: material selection for pressure vessel

You better determine or know the minimum design metal temperature because this will determine suitable material.

RE: material selection for pressure vessel

(OP)
The pressure vessel will exposed to ambient temperature. There will be a heater inside that will not exceed 40 degrees centigrade.

RE: material selection for pressure vessel

I'm thinking metal

Regards,

Mike

SnTMan,

I'm not sure if you were trying to make me laugh but that was hilarious! Obviously it is going to be metal.. It's under 1500 psi. I need help getting references to different steals regarding material selection. What can and can't be used under 1500 psi in an Argon/Heleium/CO2/Nitrogen/Air environment.

RE: material selection for pressure vessel

Or maybe this if you want to go about it the hard way ... http://www.matweb.com/index.asp?ckck=1. (A copy of the ASME Code Section II and Section VIII would also probably be helpful.)

RE: material selection for pressure vessel

I work for a pressure vessel manufacturer and normally the customer ask for the material that they want us to build the vessel. However, if you know of a chemical engineer or a chemist, he/she could tell you what material to make the vessel. I would believe that stainless would work well, such as 304/L or 316/L. Argon is inert and I would not think that it would react with much.

RE: material selection for pressure vessel

No water - no corrosion. Carbon steel will work fine and so will a host of other materials listed in ASME II.
