With people and technology, the 21st century...
At Seien Co., Ltd., we have achieved mass production of pipe products such as "extremely small R bends with a bend radius of R0.7D," which were traditionally considered difficult, and "pipe products with an outer diameter processing accuracy of 0.03mm through swaging," based on the plastic processing technology we have cultivated over many years. We have received high praise from everyone. Moving forward, we will continue to focus on further research and development and enhancing our facilities, aiming to develop new products while actively challenging other industries. 【Main Products】 ○ Pipes ○ Tubes ○ Unions ○ Hose Connectors For more details, please contact us or download the catalog.

Company information
A city that has developed alongside the sea, Kure City in Hiroshima Prefecture. Known as the city where the battleship Yamato was built, it is said to have been a place where ships for the envoys to Tang China were constructed in ancient times. Additionally, there is a legend from the Heian period that Taira no Kiyomori excavated the Onado Strait in just one day. Founded in this city, where history and legends are intertwined with reliable craftsmanship, our company has reached its 64th year specializing in pipe processing for metal piping parts used in automobiles and machinery. Our unique bending technology, which does not break even with extremely small radii, enables piping in the shortest route within limited spaces. We imbue the pipes that connect parts with our wishes for safety and our unique technology. We support Japan's manufacturing with techniques that only we can provide.
