Full ring ovalization test is performed in line pipe to assess the susceptibility to sulfide stress cracking when the material is subjected to load and sour service conditions. A full ring test was performed under BS 8701 standard1 for a 36 inches welded line pipe, X65 material. The region of interest was monitored with strain gauges to control loading at the required stress level. After test completion, the NDT and visual inspection reported indications in some areas out of the region of interest. A detailed analysis was performed to find out the sources of indications. The study included material analysis and revision of sample preparation and test setup variables. For test preparation and setup analysis, 2D and 3D finite element work was performed to understand the effect of those variables on the cracking occurrence. The finite element analysis (FEA) results showed that geometry variations, loading control and testing setup have a considerable influence on the applied stresses. It was found that some zones out of the region of interest can be over stressed due to slight modifications in loading conditions. As a part of the analysis, a new test was performed with the corresponding adjustments observed in the numerical model, and strain gauges were located at the points where the FEA showed higher stress zones. The strain gauge readings confirmed the stress fields observed with FEA. Additionally, the second tested sample successfully passed the test.
