Used for produce diameter of 1220mm carbon steel and alloy steel pipe hot induction tube expander

The total distance of the tube expander is 10-14.5 meters. The feeding and unloading mechanism of the tube expander adopts rollers to drive the steel tube forward to finish feeding.If power supply is installed in the front end of the tube expander, if coil is placed on the adjustment rack of if coil, the core reamer mold is put in place, the original tube is put in, the water pump and if power supply are turned on, and if power is adjusted, the core of the tube can be adjusted Mould and tube heating.Start the tube machine again, you can officially expand the tube.The intermediate frequency coil, compensation resonant capacitor, reactor and other components of the tube expander need to be cooled by circulating water.The electrical control part of the tube expanding machine is installed in the electric control box, and the travel switch is installed at both ends of the tube expanding machine.
Special equipment for steel tube hot hole enlargement, mainly for domestic large diameter steel pipe production cannot meet the demand of market and all kinds of steel pipe specification is not complete, meet the needs of small batch more varieties of steel pipe production, can satisfy the different material steel pipe hole enlargement and various non-standard steel tube expanding needs, is currently the main production process of large diameter steel pipe.It has been widely used in military industry, power plant construction, aerospace industry and Marine industry equipment manufacturing industry, making a great contribution to China's steel pipe industry and energy construction.

Compared with manual heating of steel pipe, the intermediate frequency tube expander simplifies the process and reduces labor cost and time.Increased production efficiency.
The equipment consists of the main engine of the hydraulic pusher, the automatic feeding and discharging mechanism, the hydraulic pump station, the tube adjusting device, the operating platform, the motor control cabinet, the intermediate frequency power supply, the compensation capacitor, the water cable, the intermediate frequency coil adjusting frame, the reactor and other components.Medium frequency tube expanding machine has an advantage is the intelligent constant temperature system, can effectively avoid due to human factors caused by the temperature is too high to pull down the quality of the steel tube and die scrap, or the temperature is too low to cause the rod and die fracture phenomenon, put an end to the unsafe factors.
