All cracks were generally oriented parallel to the housing axis and initiated at a small near-surface weld pore on the pipe ID surface. Weld material is applied to the ID surface during manufacturing to create a tapered weld build-up to aid in aligning the housing internals. The cracks were...
Consequently, an advanced CRDM housing that eliminates all canopy seal welds has been studied, verified, and now applied to Vessel Head Replacement (VHR) plants in Japan.doi:10.1016/S0029-5493(02)00011-0Kiyoshi TakanabeTakashi MiyakeYasumi Nagura...
