Dear All
Large dia Welded pipes supplied to A 928 Class 1 .These pipes are rolled from astm a 240 with plate thickness
at near to 87.5% of specified nominal thickness of Pipes.Is this acceptable practice as the wall thickness of finished pipes will be uniformally
less in thickness but within minus 12.5% tolerance
Thanks in advance

Even in the tubing business where we work +/-10% we order strip at -6% of nominal. This is standard practice.
