Specification of hot expanding steel pipe: diameter 89 ~ 1420mm,
wall thickness 30 ~ 150mm, length 3 ~ 24m.Steel tubes of various
materials can be expanded (such as p91-92 / t91-92, Q235, Q345,
45#, a106b-c, 12CrMoV).
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 the 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 patent product set cone die hole enlargement technology, medium
frequency induction heating technology, hydraulic technology in
one, with the reasonable technique, simple equipment structure, the
construction of low energy consumption, low investment, good
product quality, wide range of raw materials and products
specifications suitability, flexible variable low input of
production batch adaptability to replace the traditional steel pipe
industry tension dial hole enlargement technology, became the
resolve the shortage of large diameter seamless pipe at home and
abroad, a series of large and medium diameter welded pipe
specification is difficult to complete an important and
indispensable production capacity.With the utilization and
development of energy from solid (coal), liquid (oil) to gas
(natural gas), it is suitable for the steel pipe demand of energy
transmission pipeline.Has formed a complete hot - expanding steel
pipe processing industry.

The main components of the tube expanding machine include: stand,
main oil cylinder support plate, movable push plate, front support
plate, automatic feeding mechanism, discharging roller table, mold
support, intermediate frequency coil adjusting frame, (including
intermediate frequency heating coil) intermediate frequency power
supply, electrical control system.
Operating process of the expanding machine: the rinsed pipe is sent
to the rotary idler device on the center line of the expanding
machine.Using this rotating idler device, combined with the camera
system, the tube weld is precisely rotated to the 12 o 'clock
position to ensure that the weld can enter the groove of the upper
sector of the tool during subsequent diameter enlargement.The
lifting cone roller way lifts the pipe to the center line of the
reaming machine and the position is controlled by the displacement
sensor in the lifting hydraulic cylinder.The clamping trolley moves
forward and is controlled by a metal detector to detect the end of
the tube and to secure it. At the same time, a signal is sent to
start the feeding roller of the clamping trolley. The position is
controlled by an encoder.The pipe length is combined with the
reaming head to automatically calculate the optimal reaming
steps.The clamp jaws can be rotated to avoid damaging the tube
wall.During the advance, the height of the clamp can be adjusted to
compensate for the pipe straightening deviation and optimize the
straightening effect of the reamer.
