e sought to expand the sector for stainless steel pipe joints from welded joints for plants to those for construction, and also entered the market for flanges, drive joints, and prefabricated processing, becoming in the process the largest all-purpose stainless steel joint manufacturer in Japan. 
We have recently been working on technological developments for titanium, aluminum, and duplex stainless steel, which are far more difficult to weld and press, and have also succeeded in our efforts to develop joints for LNG installations and tankers in accordance with the rigorous standards demanded by law, such as the Electric Utility Law and Gas Utility Industry Law.
Our efforts to provide a wide range of joints for piping in many fields are unrelenting.
