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 under the Electric Utility Industry Law and the Gas Business Law, welding work between components must be performed according to welding construction methods that comply with regulations. Generally, it is necessary to order pipe fittings manufacturing and piping welding from respective manufacturers that have obtained construction methods. In contrast, if you request everything from Benkan Kiko, it is possible to centralize the planning documents and inspection applications related to regulations required for pipes, pipe fittings, and piping prefabrication, as well as management and inquiry contact points. Additionally, for items 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.
Detailed information

This is a T (tee) for high-pressure piping branching in a gas station, model API5L-L415Q-PSL2, 600A, 16.4T. To comply with local gas business laws regarding piping installation (welding method), the sleeve pipe is welded. Additionally, to accommodate the passage of pigs used for inspection and cleaning within the piping, a guide bar is welded on the branch side of the T (tee).
-
Example of Prefabricated Piping Installation This is an example of prefabricated welding of T (tees), welded steel pipes, reducers, and elbows manufactured by Benkan Kiko, along with straight pipes and flanges, culminating in special coating. Piping subject to inspection by welding contractors under the Electricity Business Act has also been centralized in terms of welding inspection applications and management, creating benefits in both cost and management.
