For alloy steel fittings for piping, please consult Benkan Kiko, the number one in domestic achievements.

- For high chromium steel primarily used in the piping of thermal power plants, such as main steam and reheat steam piping, as well as boiler tubes, we conduct long-term creep evaluation tests and confidently provide high-quality products. - We also conduct rigorous testing for product development of items other than high chromium steel. - To bring out the performance characteristics of alloy steel in high-temperature environments, managing the forming and heat treatment processes of pipe fittings is crucial. We provide pipe fittings tailored to customer needs by optimizing and standardizing the manufacturing methods and heat treatment suitable for the material. - We strictly manage testing and inspection, centered around our quality assurance department. Tests and inspections that require skill are performed and judged by qualified personnel. - In particular, high chromium steel fittings require advanced technical skills, and at Benkan Kiko, we leverage our high level of expertise to produce numerous products over many years. We specialize in large diameter and thick-walled fittings, which are widely adopted in many thermal power plants, contributing to the efficiency improvements of ultra-supercritical thermal power plants and others.
