SPECIALITY PIPE AND TUBE

Boilers play an important role in various types of plants for the power and chemical industry. With the progress of these industries, modern boilers have become larger in size and the temperature, as well as the pressure, has increased. Therefore, the steel pipes used within them must be of a higher quality.
Chita Works is one of the world's largest specialized steel pipe mills, manufacturing high quality steel pipe for boilers and heat exchangers using integrated processes ranging from raw materials to final quality control. Using their ample knowledge and experience, JFE Steel Corporation has installed up-to-date manufacturing and inspection facilities at Chita Works. Furthermore, Chita Works includes a fully expanded research division, which is making vigorous endeavors in research and development to meet the highly sophisticated needs of the individual users.
JFE Steel strives for the complete satisfaction of its customers and looks forward to their continued patronage.

Chita Works began operation in 1943 as part of Kawasaki Heavy Industries. The plant was originally constructed to produce special steels, and manufacture various types of molds, rolling rolls, and other cast steel products. When Kawasaki Steel Corporation was established in 1950, Chita Works became a part of the new company. At that time, the production system was completely renovated in response to the needs of the time and Chita Works became a specialty plant mainly producing steel pipes. Beginning with the construction of a large diameter spiral tube mill in 1961, a succession of new pipe-making shops was built. This established a production system that covered all types of steel pipe from buttwelded tube to seamless.
In April 2003, the operations of Kawasaki Steel and NKK were reorganized, and Chita Works was reborn as part of JFE Steel Corporation.
Chita Works has now become one of the world's leading pipemaking plants, boasting the world's most complete product line of pipe and tubular products made at a single facility. Chita Works is constantly aware of their mission to contribute to society by developing and applying the world's most advanced technologies.
With this in mind, they will continue to meet the diverse needs of their customers with the highest levels of product quality.
