Dear,
Regarding ASME IX QW-462.3(a) Gen note (b) : "...if the pipe being tested is equal to or less
than NPS 1 (DN 25) pipe size, the width of the bend specimens
may be that obtained by cutting the pipe into quarter sections, less
an allowance for saw cuts or machine cutting. These specimens cut
into quarter sections are not required to have one surface machined
flat as shown in QW-462.3(a). Bend specimens taken from tubing
of comparable sizes may be handled in a similar manner." Now, we are qualifying our WPS using automatic orbital welding of a pipe 3/4" and 1/4" dia with an actual wall thickness of 0.083" and 0.034" respectively. My question is,can we conduct bend test on the smaller pipe which is 1/4" dia and 0.034" wall thickness? thanks in advance for your input.
Regards,
Bolky
