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.

3 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. Boiler tubes Pipes for Piping Use HRSG module Plant piping 1.
