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....

The building of the nuclear power plant has a through hole for passing piping. A sealant is filled in the gap between the through hole and the pipe to secure the sealing property of the portion. When an earthquake occurs, relative displacement occurs in the through hole and the pipe. There is a concern that the seal material may be damaged if the relative displacement is large. Therefore, we have developed a seal structure with good displacement followability....

In domestic plants, sea water is used for cooling the auxiliary coolers and rubbers, polyethylene, epoxy resins, and etc. are employed as anticorrosion materials (linings) inside of piping that include sea water. Due to the plant aging degradations, confirmed that, as for linings that have been continuously used since the construction, the deteriorations of those performanc es caused by degradations have been found and the maintenances of lining materials become the later issue for each power company.MHI h...

In nuclear power plants in Japan, seawater is used as the cooling water. The inner surface of piping for circulating the seawater to the cooling system of each facility is lined with polymeric materials such as rubber, polyethylene (PE) or epoxy resin to prevent corrosion caused by the seawater. In recent years, cases of deterioration caused by aging of the lining materials have occurred, such as cavitation erosion in high flow velocity sections, slurry abrasion, and cracking due to the deterioration of p...
