Need: Previous studies have identified the optimum environmental conditions (temperature, electrochemical potential, and solution composition) for performing an evaluation for defining susceptibility of line-pipe steels to stress-corrosion cracking. These studies also have shown that dead-weight loaded tests, performed on tapered tensile test specimens, with an imposed cyclic load is a promising technique for evaluating stress-corrosion cracking susceptibility. However, the optimum stress ranges (AU), frequencies and test times had not been identified.
Benefit: The objective of the program was to develop an experimental procedure which will reliably assess the stress-corrosion cracking susceptibility of a given line pipe steel. Previous studies have identified the optimum environmental conditions (temperature, electrochemical potential, and solution composition) for performing such an evaluation. These studies also have shown that dead-weight loaded tests, performed on tapered tensile test specimens, with an imposed cyclic load is a promising technique for evaluating stress-corrosion cracking susceptibility. However, the optimum stress ranges (AU), frequencies and test times had not been identified.
Result: In the experimental program, the stress-corrosion cracking susceptibility of three line pipe steels was measured using the tapered tensile test technique over a range of frequencies, test times, and values. The tests were performed at Battelle's Columbus Laboratories (BCL) and at the University of Newcastle (U of N).
