  • Piping Designers . com - The Piping Designers Forum - pipe ...

    Hi Ven, Common practice, in the absence of any references, is to assume the mill tolerance for wall thickness for seamless piping to be 12.5%. This is, in fact, the figure quoted by ASTM A53 a standard which incidentally applies to both seamless and welded pipe. This means that the piping wall thickness may vary by 12.5% or, stated differently, the ratio of the thinnest portion of pipe wall to ...
