Hello, Anyone could help me to find in what part of the code ASME explains the rules or requirements to increase the inside diameter of a 90º bend?
I have several 90º bends 30" SA234WPCW Sch XS. After a dimensional test, the inside diameter in some parts of the ends is below of the ANSI B16.25 tolerances (5 - 8 milimeters). The thickness is OK. The supplier recomend me a phisical process to increase the diameter (pushing a special tool into the end of the bend without thermal treatment). This process could produce a weakness in this part of the fitting?
Thanks in advance.
