We will eliminate fluid leaks in the fastening of dissimilar metal piping and achieve maintenance-free connections of dissimilar material piping.
Asahi Kasei Corporation has developed an explosive welding technology that utilizes the instantaneous high energy generated during the explosion of explosives to metallurgically join dissimilar metals in a cold state. This technology enables the strong bonding of aluminum, aluminum alloys, and stainless steel. ■ CCJ(R) "Cryocoup Joint" CCJ(R) is a piping material suitable for extremely low-temperature fluids (such as LNG and liquid nitrogen) that achieves a welded integrated structure between stainless steel pipes and corrosion-resistant aluminum pipes. 【Features】 1. Stainless steel pipes and aluminum pipes can be directly welded through CCJ(R). Compared to flange connections, there is no risk of fluid leakage, making it advantageous for safety. 2. Being boltless, it allows for a smaller outer diameter compared to flanges, enabling a compact design. 3. The bonding strength between dissimilar metals is stable against thermal cycles, with minimal reduction in strength. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive cladding method, and it has received high praise in various fields since its release. The explosive cladding method utilizes the enormous energy released during an explosion to instantaneously bond metal plates together, thereby producing clad steel plates. BA Clad is used for plants and equipment in the chemical industry, petroleum refining, petrochemicals, and power generation, and is exported widely both domestically and internationally, either as flat plates or various components. It is used as corrosion-resistant and heat-resistant structural materials for power plant condenser tube sheets, heat exchanger tube sheets for chemical plants, shells, and end plates, among others, and its applications are continually expanding to include rolling mill liners, electrodes, cryogenic joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We offer solutions related to metal joining (dissimilar metal joining, similar metal joining) and cladding. We can provide joining characteristics such as material properties, joining strength, minimization of alloying at the joining interface, and joining area, which are difficult to achieve with other joining methods, such as various welding techniques, diffusion bonding (roll bonding, HIP, etc.), friction joining (friction welding, friction stir welding (FSW)), electromagnetic pressure bonding, brazing, plating, and thermal spraying.
