JOURNAL FREE ACCESSA newly corrosion resistance steel containing Sn for steel structure has been developed. The corrosion resistance of this developed steel was evaluated by SAE J2334 cycle test and exposure test at LNG plant. As a results, this developed steel reduced paint delamination area and corrosion depth at its paint scribe. Therefore, the developed steel is expected to reduce a paint repairing cycle of steel structure under atmospheric condition. We report the corrosion resistance of this developed steel and give the report regarding exposure test at LNG plant.View full abstractDownload PDF (696K) -

JOURNAL FREE ACCESSWe developed the ceramic type Terminal-header with FURUKAWA Electric Co. , Ltd. in 1987. It was designed to be used for 30 years, though the knowledge about the deterioration condition is not so much. So we tested the deterioration of ceramic type terminal-header that has been used in our LNG-terminal. We report the results in this paper.View full abstractDownload PDF (815K)

JOURNAL FREE ACCESSIn steels for welded structures, it is well known on Koa, fracture toughness of crack arrest, that log Kca shows linear dependence on reciprocal of T and converges at a certain value of 1⁄T, which means existence of “pivot”. In the present paper,Kc , fracture toughness for crack initiation, is also shown to have a pivot. The reason for existence of the pivot is explained by setting a presumption that any steel for welded structures except steels for low temperature use has the transition temperature Ts about -100°C, where Ts means the lowest edge of the temperature range for brittle fracture in the general yield condition.View full abstractDownload PDF (75K)
