... yielded zones at the heavy weld where the SCC crack initiated. Acoustic emission (AE) examination conducted for two in-service urea reactors revealed AE event clusters at the heavy weld and subsequent phased array reexamination confirmed the existence of propagating defects in the heavy weld. The results...

.... Results of strength tests performed here indicated that strains of 0.002 to 0.003 or better are possible in the safe design of tanks and pressure vessels. In addition, more accurate determination of design limits is possible if methods like acoustic emission are incorporated in the design process. All...
