Sumikin Kikoh

BENKAN KIKOH Corporation, known as Sumikin Kikoh, is a Japanese manufacturer headquartered in Ota, Gunma Prefecture, supporting people's lives through the world's lifelines. Its buttweld pipe fitting business produces welded-type fittings that are joined to steel pipe by butt welding, whose high reliability has led to adoption in core infrastructure piping for electric power, gas, oil refining and water purification, with carbon steel and stainless steel seamless products, JIS certification of its butt-welded fittings, standard approvals and a published manufacturing range.

The company's high pressure gas container business manufactures seamless steel vessels for compressed gases such as oxygen and nitrogen, demanded by law to deliver high safety and reliability, with defined production and inspection processes and Chinese certification among its approvals. Alongside these, BENKAN KIKOH produces flanges, welded steel pipes and piping prefabrication, supports design with FEM analysis, and publishes catalogs, price lists and dimension tables for engineers.
