WebInduction bending is one of the means of bending pipes for 5D and other bends. Local heating, using high-frequency induced electrical power, is applied. An induction coil is placed around the pipe and heats a circumferential area of the pipe at a temperature between 850 to 1100 degrees Celsius. WebDHF is endeavoring to be a comprehensive prefabricated piping system manufacturer. To achieve this goal, we conduct secondary prefabrication of our high-frequency pipe bending, the prefabrication of polyethylene lined pipes, and adopt the Weldless Piping System utilizing our hot branching processes. Types of prefabrication 01
