Inside diameter under tolerances
Inside diameter under tolerances
(OP)
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.
