HIGH FREQUENCY INDUCTION BENDING
MORE
This processing technology utilizes high-frequency induction heating for the hot bending of pipes, H-shaped steel, and other parts.
This specific technology was first developed a commercialized by DHF.
Its high-level precision processing and excellent mechanical characteristics have been highly evaluated and widely introduced in various industrial fields.
POLYETHYLENE LINING
MORE
DHF successfully developed and commercialized corrosion- resistant resin materials and lining technologies to prevent the internal corrosion of steel pipes, external corrosion of buried pipes, and corrosion that occurs both inside and outside the pipes. DHF is proud of its 45-year history of manufacturing corrosion-proof and corrosion-resistant steel pipes.
PREFABRICATION
MORE
DHF's manufacturing facilities allow for integrated production by conducting the prefabrication of high-frequency bent pipes or lined pipes manufactured in the plant. We are also capable of conducting secondary processing, as well as the prefabrication of general-purpose piping products.
