Compact heat exchange components with excellent thermal conductivity! Lotus-type metal components.
It is possible to manufacture heat exchange components that combine different materials according to the usage environment! Improved thermal conductivity through metallurgical integrated bonding utilizing explosive energy.
Using the ultra-high pressure generated by the explosive energy of explosives, it is possible to manufacture lotus-type metal components. By inserting a small-diameter metal pipe into a large-diameter metal pipe and applying explosive shock compression from the outer circumference, a lotus-type metal component that is metallurgically bonded and integrated can be obtained. Our lotus-type metal components have excellent thermal conductivity, enabling compact designs for heat exchange components. Additionally, the material of the piping can be selected according to the usage environment, and it is also possible to create hybrid lotus materials by combining different materials.

Company information
BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive welding method, and it has received high praise in various fields since its launch. The explosive welding 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, ultra-low temperature joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We propose 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 that 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 welding, brazing, plating, and thermal spraying.
