... specimens are essentially prebulged by machining a taper or a flange on the cylinders ( Fig. 16 ). Compression then causes lateral spread of the interior material, which expands the rim circumferentially while applying little axial compression to the rim. Therefore, the tapered and flanged upset test...

It is common to test pipelines hydrostatically to hoop stress levels of 90 to 105% of their specified minimum yield strength. In addition, this pressure is maintained for 8 to 24 h. This ensures that the pipeline...
