Butt-welded pipe fittings are designed to permanently join piping by welding them together. The "BENKAN" brand, including BENKANKIKOH, is recognized globally as synonymous with welded pipe fittings, and we have absolute confidence in the quality that underpins its reliability. They are intended for general piping use with a temperature range of approximately 0 to 350°C and a pressure of about 1 MPa.

Benkang Kiko's welded pipe fittings inherit the technological expertise cultivated by Nippon Benkan Kogyo, established in 1947, and Nittetsu Sumitomo Kiko, which has been manufacturing since 1953. They are capable of handling various materials, not only carbon steel but also stainless steel, alloy steel, and non-ferrous metals, as well as a wide range of diameters from 1/2 to 80 inches, enabling them to adapt to various piping environments (design and usage conditions). Additionally, they have obtained various certifications necessary for production, such as JIS and ISO 9001, and have a robust technical and quality assurance system to support these certifications.

• Piping materials (copper pipes, cast iron pipes)
• Fittings

Piping joined with "welded pipe fittings" cannot be disassembled once joined, but by adopting "pipe flanges" that connect pipes with bolts and nuts, disassembly becomes possible. Benkan Kiko specializes in sales of stainless steel welded types, primarily supplying domestic plants, including chemical factories, water treatment facilities, and construction-related projects.

At Benkan Kiko, based on our expertise in manufacturing welded pipe fittings, which includes "plastic processing," "welding," "machining," and "handling various materials," we value feedback from our customers and strive to develop new products according to their requests. We are committed to collaborating with our customers to explore ideas that may not be found anywhere else, asking, "Can you make something like this?" For example... - We would like you to weld a steel pipe (single pipe) to an elbow and deliver it. - A T (tee) with a complex shape, and we are unsure if it can be manufactured. - We don't know which manufacturer to ask. *In the "Applications/Examples of Achievements" section below, we introduce some of the products we have manufactured so far!
