The pipe material is cast black iron. Used currently for gaseous argon/CO2 (98%/2%) Emixal for industrial welding. Proposed change to system with a gaseous argon/O2 (98%/2%) Emixal.
Current operating conditions: 50 psig, ambient temp, pipe is fairly new (within 10 yrs).
Am starting a new design project and am trying to find the MDMT for a segment of black iron pipe that's in an exiting system. Was wondering if anyone could provide some assistance.
