Many Swagelok connections are used in the instrumental tube pipe of Nuclear power plant because Swagelok conne ion is easy to put on and take off quickly. Although Swagelok connection is easy handling, it occurs very sma ll amount of leakage in some case. For the purpose of development of quick repair method for small amount leak e of Swagelok connection, we considered the base technique about the miniature cramp for Swagelok connection....

Development of Miniature Cramp for Swagelok Connection Temporary Repair

In plant management, aged facilities have been serious problem. Especially, carbon steel causes many accidents on the problem of corrosion. we have managed remaining life time to a use limit, based on the Chickness by ultrasonic measurement result in the fixed point. However, most accidents have generated bec ause of the failure to notice localized metal decrease. The authors have developed a continuous thickness measurement system utilizing ultrasonic waves whic h scans metal loss in tank, and pressure ve...

In petrochemical plant, many steel piping lines which used on various conditions exist. For the reason, the management about ageing of piping is a serious problem. Recently, we are anxious about the increase in the plant accident in which Ageing of piping occurs by the cause. In the manage ment of pipe, it is the most serious problem that is overlooking of the local metal loss to be caused of corrosion, erosion, etc.. Authors develo ped the ultrasonic continuously thick...
