What do pipe grades such as AA5E, AA13E, AA7B, etc. mean respectively?
Reply #22021-03-12
It should be the pipe grade specified by the engineering department of a particular institution; the \"Pipe Grade Tables\" of different institutions specify different grades. Different pipeline grades define various specifications regarding the material of the pipeline, the operating pressure and temperature ranges, the types of fluids it can carry, the methods of connection, as well as the requirements for welding and testing.
