When the Wholesale Pipe Expanding Machine produces the pipe, the intelligent control of the intermediate frequency power supply will be heated to the required temperature to maintain a constant, effectively avoiding human factors and causing the high temperature of the steel pipe to produce the steel pipe quality and scrapping the mold, while avoiding the overheating of the pipe expanding machine. In the process of pushing, the mold breaks, causing unsafe factors. Compared with manual manual operation, the steel tube is heated, energy saving and environmental protection, simplifying the operation procedure and reducing the labor cost. The hydraulic pipe expanding machine is equipped with two temperature measuring intelligent automatic temperature control, so that the Hot Pipe Expanding Machine Quote can set the heating temperature according to different steel pipes, select the heating temperature of the steel pipe and keep it constant, and can display and record in real time, and can save the parameters of heating temperature.
