Dear all, in the past i seem to recall an ANSI standard wrote ( pipe size 1 1/4" , 1 1/2" , 5" ) were not reccomended. Something of us remember what is this ANSI standard ( sorry for my english) ?
Good days to all; I'm a question regarding the minimum/maximum temperature range of duplex/superduplex materials. I'm Considering Valves in stainless steel ( F316/CF8M ) with the stem in ASTM A 182 F51 ( or F53,F55 ) How is the range of min and max temperature?
