Used for produce diameter of 1020mm carbon steel and alloy steel
pipe hot induction tube expander
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.
Tube expander is a special equipment for hot diameter expansion of
steel tubes. It is designed for the production of large diameter
seamless steel tubes and the specification is not enough to meet
the domestic and foreign market demand.It is the main production
technology of large diameter steel tube at present.The main power
source of the equipment is the parallel equal-speed push machine
with two or four oil cylinders. The valve platform of the pump
station adopts the integrated form. The power of the
medium-frequency heating power supply, the thrust and stroke of the
oil cylinder are set according to the outer diameter and length of
the steel tube to be expanded.

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.
The equipment is used in the production of seamless steel pipe,
straight seam welded pipe, coil pipe and so on.Expandable steel
tube varieties are: various carbon steel, alloy steel, stainless
steel and so on.
The expanding equipment mainly includes: the frame, the main oil
cylinder support plate (including the main oil cylinder), the
movable push plate, the front support plate, the automatic feeding
mechanism, the discharging roller table, the mold support, the
intermediate frequency coil adjustment frame (including the
intermediate frequency heating coil), the intermediate frequency
power supply, the electrical control system and so on.
