From Table A-1 (B31.3) for the material A312-TP321 (page 172) There are two material selection (with different allowables) one is pipe smls >3/8 in. thk. and the other is =< 3/8 in. thk. & wld..What does thk. stands for? Is this the pipe thickness?


Does CAESAR II automatically selects this material as per thk...?

Thanks in advance....
