Monel 400 VS Oxygen

Monel 400 VS Oxygen

(OP)
Hi,

My customer wants to use Monel 400 material for a piping transporting 100% oxygen pressurized inside a pressure piping having walls at 350F.  

Do you see any issues?  If yes, what are the references (standard, books, etc.) supporting your issues.

Thanks in advance for your help.

RE: Monel 400 VS Oxygen

There are a number of standards for this service.
The one that comes to mind is the CGA.
You will need a standard for valves, fittings and other parts.
Maximum flow velocity is also an issue along with temp and pressure.
Monel is a good choice for this service. The old DMIC data from the 60's shows Monel resisting ignition in oxygen at high temperature and pressure.

I would suggest you review NFPA 50 and ASME B31.3.
