This paper introduces the system advantages of hydraulic pipe expander  

Advantage of hydraulic expanding machine equipment system: the hydraulic expanding machine reproduce when expanding intelligence control medium frequency power supply will be heated to the temperature needed to maintain a constant, effectively avoid artificial factors caused by steel pipe under the high temperature to produce steel pipe quality and mold scrapped, and to avoid the low temperature in the system of push mold interchanged fracture phenomenon, cause the unsafe factors.  Compared with manual operation, it is energy saving and environmental friendly, simplifies the operation procedure and reduces the labor cost.  The hydraulic pipe expander is equipped with two intelligent temperature measurement and automatic temperature control, so that the hydraulic pipe expander can set the heating temperature according to different steel tubes, select the heating temperature of the steel tubes and keep it constant, and can display and record in real time, and can save the heating temperature parameters.  

The hydraulic pipe expander is mainly composed of a frame, a main cylinder support plate (including the main cylinder), a movable push plate, a front support plate, an automatic feeding mechanism, a feeding roller table, a mold support, an intermediate frequency coil adjusting frame (including the intermediate frequency heating coil), an intermediate frequency power supply, and an electrical control system
