Re: [MW:31328] Pre heating as per ASME SEC I / VIII DIV I

As far as designers are concerned they talk about specified thickness.

Sometimes thickness may be  bit more or less then the specified thickness but within the tolerance band.

Specified thickness of the Pipe is 12.7 mm 

Actual thickness measured is 13mm 

Client specified preheating for  12.7 mm (=/>) =75 Deg C

Is preheating is to be decided on specified thickness or  actual thickness?
