Re: grade A astm pipes
I disagree my friend. In ammonia piping standard we shoud use Carbon steel pipe and shall be ASTM Standard A 53 Grade A or B, Type S (seamless) or ASTM Standard A 106 (also seamless), except where temperature-pressure criteria mandate a higher specification material. In medium pressure steam applications as well we use this same type of pipe material.
