Seifert, R L

With this new program for determining the strength of a corroded pipe, corrosion engineers can evaluate a corroded area on a pipeline by merely assembling five specific data from company records and two dimensions of the external corroded surface of the pipe. The company data include the maximum allowable operating pressure, the outside diameter and wall thickness of the pipe, the steel's maximum yield strength, and the design derating factor. Using these data plus the maximum corrosion-pit depth and the length of the damage area, the calculator will determine the safe operating pressure for that pipe and alert the operator to an unsafe corrosion situation that requires either immediate repair or a reduced pressure.
