Benkan Kiko provides piping materials that meet the requirements of nuclear power management.
Benkan Kiko has a wealth of delivery experience in welded pipe fittings for all nuclear power plants in Japan. Utilizing our expertise in stringent quality control for nuclear applications, as well as the management of documentation and quality records, and the technology for long and circumferential welds on items subject to inspection by welding contractors, we manufacture not only items subject to such inspections but also prefabricated piping that requires nuclear management, which has a significant track record for the necessary remedial work for the recent restart of nuclear power plants. In particular, we produce and deliver prefabricated piping that combines fittings, flanges, nozzles, and nipples for fire protection piping, which traditionally does not require nuclear management, and we also conduct strength calculations for these flanges, nozzles, and nipples based on JSME (Japan Society of Mechanical Engineers) standards. We can manufacture using both stainless steel and carbon steel (galvanized), and we also respond to various other requests.

Applications/Examples of results
We have a track record of supplying to various fields including nuclear power plants, thermal power plants, LNG plants, petrochemical plants, gas pipelines and stations, shipbuilding plants, and others. When assembling plant piping under the Electric Utility Industry Law and the Gas Utility Industry Law, welding work between materials must be performed according to welding construction methods that comply with regulations. Generally, it is necessary to order joint manufacturing and piping welding from respective manufacturers that have obtained the construction methods. In contrast, Benkan Kiko centralizes the production of pipes and joints, as well as prefabrication work, allowing for the unification of necessary regulatory-related planning documents, inspection applications, and management and inquiry contact points for both pipes and joints, and piping prefabrication. Additionally, for products subject to the Electric Utility Industry Law, it is also possible to reduce the number of pressure tests required by regulations, which can lead to cost savings.
