Welded pipe fittings for piping, made of alloy steel (low alloy steel, high chromium steel)
For alloy steel fittings for piping, please consult Benkan Kiko, the number one in domestic achievements.
Alloy steel fittings for piping contain elements such as Cr (chromium) and Mo (molybdenum), and are primarily used for main piping and reheating piping in boilers, biomass power generation, thermal power generation, as well as high-temperature and high-pressure piping in petroleum refining and chemical industries. Benkan Kiko has a proven track record in the manufacturing of various alloy steel fittings. Additionally, for some materials, we have stock of the steel pipes required, allowing us to deliver relatively quickly. Achieving a carbon-neutral society necessitates reducing CO2 emissions through increased efficiency in plants. Low-alloy steel and high-chromium steel pipe fittings that can withstand harsh high-temperature process environments have become essential products under such conditions. Furthermore, Benkan Kiko is also contributing to society by exploring the manufacturing of special specifications and new materials. <Representative Steel Grades> (JIS Standards) PA12, PA22, PA23, PA24, PA25, PA26 (Thermal Power Standard Materials) Fire STPA28, Fire STPA24J1, Fire STPA29 (ASME/ASTM) A234WP1, WP12, WP11, WP22, WP5, WP9, WP91, WP92
basic information
- 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.
