Welded pipe fittings for LNG transport vessels
Welded pipe fittings from Benkan Kiko are also used in LNG transport vessels.
basic information
For vessels exceeding 100 tons in the main register, their performance (including structure and equipment) must be inspected and certified (approved) by classification societies to meet certain standards. This inspection includes welded pipe fittings among the items subject to inspection (by piping systems). We supply reliable welded pipe fittings approved by the specified classification society. We have the technical capabilities and experience to meet various classification societies, including the Nippon Kaiji Kyokai (NK), American Bureau of Shipping (ABS), Lloyd's Register (LR), Bureau Veritas (BV), and others, and we respond not only to the specifications required by classification societies but also to a wide range of additional requests tailored to customer needs. In recent years, in response to the shale gas revolution in the United States, there has been a significant demand for LNG (liquefied natural gas) transportation, and we have received numerous requests for welded pipe fittings for LNG vessels from various companies. During the transportation of LNG, it is necessary to compress the volume to 1/600 and maintain it below -162°C. Additionally, due to the nature of maritime transport, there are demands for higher reliability in the piping related to this equipment, considering factors such as swaying and uneven loads. Our company continues to evolve based on the achievements and experience cultivated over many years, consistently supplying highly reliable products.

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 constructing plant piping under the Electric Utility Industry Law and the Gas Utility Industry Law, welding work between materials must be carried out according to welding construction methods that comply with regulations. Generally, it is necessary to order joint fabrication and piping welding from respective manufacturers that have obtained the construction methods. In contrast, at Benkan Kiko, by centralizing pipe and joint manufacturing and prefabrication work, it is possible to unify the necessary regulatory planning documents and inspection applications related to pipes, joints, 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 reduction effects.
