The Pipe Business Division is engaged in the manufacture and sales of a variety of piping materials, and the design of piping prefabrication thanks to high-frequency induction heating technologies, including pipe bending, heat branch extrusion, and polyethylene powder lining. |
The accumulated high-frequency induction heating technology is used to perform the surface treatment of mechanical parts. For the manufacture of rolls, we employ the integrated production and regeneration process of high-precision rolls with high wear-resistance using the special steel we have developed. |
Various types of equipment and machines are produced using the technologies of heat treatment and induction heating, and tools are developed for induction heating in plant maintenance, which helps to reduce the time of maintenance, repair, and periodic inspection. |
With the mechanical fixing method for the reinforcing steel bar ends that has improved reinforcement workability and concrete filling as well as the earthquake-resistant design of reinforced concrete structures, integrated steel bar end fixing materials of high quality are formed using DHF's induction heating. |
