Stress Corrosion Cracking of Pipeline Steels in Fuel Grade Ethanol and Blends
The main aim of this project was to evaluate alternate standard test methods for stress corrosion cracking (SCC) and compare them with the results from slow strain rate test (SSRT) results under equivalent environmental conditions. Another important aim of this project was to develop a phenomenological understanding of SCC of pipeline steels in fuel grade ethanol (FGE) and FGE/gasoline blends. To achieve these objectives, tests were going on in all fours task areas of this project in the last quarter (July to Sept. 2011), when the project was terminated. This report describes the technical work done on different tasks along with the summary of final status of these tasks in terms of key results. The tasks were as follows: (1) Evaluate Tapered Tensile Tests to Determine Threshold Stresses for SCC; (2) Four-Point Bend (FPB) Tests on Pipeline Sections to Simulate Pipeline Loading; (3) Determine the Threshold Stress Intensity Factor for SCC (K sub ISCC) and Crack Growth Rate Measurements (Fracture Mechanics Approach); and (4) Phenomenological Understanding of SCC in FGE.
