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 strict quality control for nuclear applications, management of documentation and quality records, and techniques for long and circumferential welding of items subject to inspection by welding contractors, we manufacture not only items subject to welding contractor inspection but also prefabricated piping where nuclear management is required. We have a significant track record in construction measures necessary for the recent restart of nuclear power plants. In particular, we manufacture and deliver prefabricated piping that combines fittings, flanges, nozzles, and nipples for fire protection piping, which traditionally does not require nuclear management. 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 are ready to meet various other requests.

Applications/Examples of results
We have a track record of supplying to various fields including nuclear power and thermal power plants, LNG plants, petrochemical plants, gas pipelines and stations, shipbuilding plants, and others. When assembling plant piping in accordance with the Electricity Business Act and the Gas Business Act, welding work between components must be carried out using welding methods that comply with regulations. Generally, it is necessary to order joint manufacturing and piping welding from respective manufacturers that have obtained 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 planning documents, inspection applications, and management and inquiry contact points related to pipes, joints, and piping prefabrication. Additionally, for products subject to the Electricity Business Act, it is also possible to reduce the number of pressure tests required by regulations, which can lead to cost savings.
