Introducing the large-diameter monaka-style elbow with an outer diameter exceeding 2 meters!! This 80-inch (outer diameter 2032mm) large-diameter elbow is available. Leave the manufacturing of large-diameter elbows to Benkan Kiko.
The name "Monaka" originates from a type of Japanese confectionery called "monaka," which consists of two layers stacked together. 1. Enhanced facilities enable the production of products tailored to your needs When manufacturing large-diameter elbows, a method may be employed that combines steel pipes known as "maita bends" and "ebi pipes" to create elbow shapes. The monaka manufacturing process requires molds and high-output press machines. Our facilities are well-equipped, allowing us to produce products that meet our customers' requirements. 2. Fewer weld seams reduce the risk of welding defects Due to the manufacturing method of combining steel pipes through welding, maita bends tend to have many weld seams, resulting in more inspections. Our elbows have only two weld seams in the longitudinal direction, significantly fewer than maita bends, thereby reducing the need for inspections on weld seams and minimizing the quality risks associated with welding, allowing for safer usage. 3. Smooth shape minimizes the impact on fluids Maita bends have a cornered shape due to the combination of steel pipes, while our formed elbows have a smooth R shape, which minimizes the impact on fluids. We can accommodate various materials (for details, please refer to the section below), so please feel free to contact us.

basic information
We can accommodate materials ranging from stainless steel, carbon steel, and alloy steel to special materials such as aluminum and nickel. In addition to elbows, we also manufacture reducers, tees, and caps, which are essential in piping. At Benkan Kiko, we can produce butt-welded pipe fittings in a wide range of sizes from 1/2B (1/2 inch / 15A / outer diameter 21.7 mm) to 80B (80 inches / 2000A / outer diameter 2032 mm). Our company has accumulated wisdom and experience over many years, and we are particularly confident in the welding quality of steel plate welded pipe fittings. Large-diameter products are mainly manufactured at our Osaka factory in Hyogo Prefecture. The Osaka factory has obtained various certifications, including Japanese Industrial Standards (JIS) and PED certification, as well as various overseas standards. We possess many welding methods, including those based on the Electric Utility Industry Law, Gas Utility Law, first-class pressure vessels, and boilers. Based on these qualifications and certifications, we provide products with reliable technical skills and quality assurance systems, which have received positive feedback from our customers.
