Bulge forming (hydroforming) has now evolved and is being used in various processing applications.
Bulge forming (hydroforming) is a method of processing materials by applying high internal pressure and axial load (axial pushing) to a pipe material (such as steel pipes) placed in a mold, deforming it into a shape that conforms to the mold. It is a plastic processing technique 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, enabling complex shapes to be created. 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 allows for complex shapes while also achieving cost reductions. 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 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 industrialized field is actually said to be the molding 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 many years, providing our customers with reliable products.
