Mill Tolerance and ASME B31.8

[AlBaigMughal]

Dear Sir,

Sorry for being so late. I was out of town and so, couldn't respond.

This is all right what you tried to tell me. I am myself of the view that we should include the mill tolerance but i believe ASME B31.8 doesn't recommend us. You can see the definition of "t" in section 804.222 as:

"Nominal wall thickness, t, is the wall thickness computed by or used in the design equation in para. 841.11 or A842.221 in Chapter VIII. Under this Code, pipe may be ordered to this computed wall thickness without adding allowance to compensate for the underthickness tolerance permitted in approved specifications."

Now, this is again something very confusing. Anyways, I still recommend to incorporate Mill Tolerance so that we may have a safer result.

Thank you very much for your continued support. Hope to have this always,

AlBaigMughal
