Hello everyone,
Problem: The new plug of the air cooler heat exchanger made from stainless steel leaked during the leak test. The plug was new and never used. The defective plug was sent to be tested using PT and PAUT and it found the defect at the center and along the entire length of the plug (that's why it leaked during the leak test). I'm confident that this defect is not due to the machine processing used to create the plug.
The plug was sent back to the supplier for the RCA but finally, they didn't respond to the inquiries anymore. So, I'm here to get your thoughts on the possible root cause of the plug defect. Is it an inherent discontinuity or defect from the original melting and solidification of the metal?
Thanks for any help.
