the design code is ASME B 16 9
DESIGN PRESSURE 111 BAR
DESIGN TEMPERATURE -20--80 °C
12" NATURAL GAS PIPE
i would like to know the schedule and size of the fittings to use (Flanges; tee; elbow...)
WELL,I am not familiar with the ASTM code , I am actually requested to provide a vendor with the class , thickness and the grade of fittings and the flanges .The working pressure of the main pipe is 111 bar .The client has recommended ASTM 694 F60 .
Where should I start .
Thanks
