Bulge forming (hydroforming) has now evolved and is being utilized in various processing applications.
Bulge forming (hydroforming) is a method of processing materials by applying high internal pressure and axial load (axial pushing) to tubular materials (such as steel pipes) placed within a mold, deforming them into shapes that conform to the mold. It is a type of plastic processing using various alloy steel pipes, including carbon steel, stainless steel, aluminum, copper, and brass. Using bulge forming offers the following advantages: 1. It allows for integral forming, making complex shapes possible. This improves the rigidity of the processed products and leads to enhanced quality. 2. It enables material thickening forming, allowing for right-angle bends in steel pipes, which can reduce processing time and increase processing speed. Thus, it is a forming method that not only allows for complex shapes but also enables cost reduction. Our company is capable of manufacturing welded pipe fittings, including T (tee), special T (tee) at 45° YT, crosses, laterals, and more. We also accept inquiries for welded pipe fittings tailored to customer needs in terms of material, diameter, and thickness, as well as for the production of special items, so please feel free to contact us.

basic information
Since its development in the United States in 1940, it has evolved over time, and active applied research has been conducted, particularly in the automotive industry. However, the first field to be industrialized is actually reported to be the forming of welded pipe fittings in the shape of a T. At Benkan Kiko, production of T-shaped fittings through bulge forming began in 1978 under its predecessor, Japan Benkan Kogyo Co., Ltd. We have continued to evolve and pass down this important technology over the years, providing our customers with reliable products.
