Technology and Qality
Since it's founding, Nishiyama Seisakusho has greatly contributed to the industry-wide development of highly precise, high performance drawn carbon steel tubes.
Our carbon steel tube manufacturing delivers products of superior cost performance and quality through our technologically advanced production processes and constant pursuit of process improvement. In addition, we are constantly scanning the horizon to realize technological advances required to develop the market's future product needs. The superior performance of original products such as our double-tube heat exchanger demonstrates this ongoing commitment. Ever smaller/thinner, ever-greater technology and quality, it is our determination to work night and day to provide better products for our customers.
Nishiyama Seisakusho is especially proficient at producing cold drawn steel tubes with a width of less than 10mm.
Production begins at a width of 2mm, and in tubes of less than 6mm we hold approximately 80% of domestic market share. High performance, high quality tubes of this nature are required throughout a wide sphere of industry and manufacturing including motor vehicles, construction and industrial equipment.
Furthermore, through an extended heat treatment using a non-oxidation bright annealing furnace, tube surface has a good condition, thereby removing the entire need for acid pickling.
