At higher pressures use extra heavy black iron pipe. High-pressure steel Monel or aluminium-iron-bronze valves Aluminium and stainless steel are preferred but iron steel or brass are acceptable Aluminium preferred. Iron and steel are satisfactory. Brass though tarnished is acceptable Most common metals Most common metals Most common metals Most common metals Most common metals Iron and steel Most common metals when dry Most common metals Most common metals when dry Most common metals Stainless steel and copper-free steel alloys and aluminium. Iron and steel for dry gas Most common metals Most common metals Most common metals for pure gas. Copper or glass-lined equipment for carbonyl in the presence of carbon monoxide Most common metals for dry gas. For moist gas use 18 8 stainless steel PTFE Any common metal Most common metals for dry gas. For moist gas use 18 8 stainless steel Nickel and Monel are preferred.
