[MW:1676] Re: Nominal Thickness

Dear Mr. Babu,

Unless otherwise designated, references to pipe wall thickness always mean the nominal, or average, wall thickness.  Most ASTM tolerances on regular pipe products specify that wall thickness of pipe at any point is to be no more than 12 1/2% under the nominal wall thickness specified.  This means that a minimum wall of 0.875 times the nominal wall could apply for regular mill rolled steel.

Thank you,

 

Regards,
