Dear All,
TML or Thickness Measurement Locations are marked on piping for
inference of corrosion rates and inspection intervals. I have been
reading API 570 and API 574 to determine the recommended size of a TML
according to cade but cannot find it.
Can anybody please indicate?
Thanks and Regards,
Muhammad Ali
