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 materials 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 the construction methods. In contrast, if you entrust everything to 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 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.

Detailed information

• 

  This is a thick-walled elbow with a neck section at the end. It is manufactured at a special angle of 89.43° instead of the standard 90°. In this way, we can produce special fittings tailored to the customer's piping design.

• 

  This is also a thick elbow with a neck at the end, but it has necks of different lengths on both ends. Additionally, it is manufactured with an even thicker 70.0T.

• 

  T(S) INCOLOY 825 18B 28.5T Thanks to a wealth of material purchasing sources, we can accommodate various materials.

• 

  Lateral SFVAF22A 600AX500A 32.0T/27.0T This is a lateral made of forged steel for power plants. Joints that cannot be manufactured through plastic processing can be supplied as forged products. The product in the photo is a butt-welded type, but we can also accommodate SW and PT.

• 

  This is a T (tee) for high-pressure piping branching within a gas station, 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).

  Examples of Prefabricated Piping Construction 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 Electric Utility Industry Law has also centralized the application and management of welding inspections, creating benefits in both cost and management.
