Base Line Pipe data
Base Line Pipe data
(OP)
I have always performed this task but I am now asked to show what document or regulatory body requires that base line data be taken on piping and equipment installations. It may have been in the federal register. Any help will be appreciated





RE: Base Line Pipe data
a) A corrosion rate for a piping circuit may be calculated from data collected by the owner/user on piping systems of simular material and service.
b) If data for the same or simular service are not available, a corrosion rate for a piping circuit may be estimated from the owner/user's experience or from published data on piping systems in compairable serice.
c) If the probable corrosion rate cannot be determined by either method above, the initial thickness measurement shall be be made no more than 3 months of service.
So, 90 days is the default as per API 570
