..., hydrogen. In Keywords: hydrogenation reactors, long-term service, China, a considerable number of hydrogenation reactors have material degradation, inspection, safety assessment, remain life been in service for more than 20 years, and the longest service prediction has reached 48 years. How to ensure...

... two recently developed Chinese standards for nondestructive testing and safety assessment of electrofusion joints. These standards illustrate inspection process, sample block, defect characterization and safety assessment. Some research, applying these standards for inspection and safety assessment...

... for the wall thickness of all DLR structural components was evaluated at the increased pressure. A safety assessment employing risk-based inspection (RBI) methodology was carried out on the DLRs to evaluate the risk in the case of failure of the DLRs. The probability of failure (PoF) and consequence of failure...

The safety assessment on 2 mm deep surface crack was carried on. cast iron dryer relative hardness wall-thick measurement ultrasonic...

... barriers against failure were proven. For all load cases the relevant load path temperatures proved to be in the upper shelf regime of fracture toughness, where ductile fracture is the failure mechanism and brittle fracture is precluded.
