To provide a forming system and a forming method capable of improving sealing properties when a fluid is supplied to a metal pipe material. In a forming system (100), a controller (20) controls a heater (6) so as to heat end parts (14a and 14b) of a metal pipe material (14) at least before the supply of a fluid by a fluid supply unit (10). Therefore, at least before the supply of the fluid by the fluid supply unit (10), the end parts (14a and 14b) of the metal pipe material (14) are likely to be deformed by being heated by the heater (6). In such a state, the end parts (14a and 14b) of the metal pipe material (14) can be easily expanded by a pressing force generated by pressing nozzles (7 and 8) against the end parts (14a and 14b) of the metal pipe material 14, respectively. Accordingly, the nozzles (7 and 8) can secure sufficient airtightness via expanded parts (14c and 14d) of the metal pipe material 14.

To provide a forming device and a forming method capable of suppressing a reduction in strength of a formed material and of forming a flange part having a desired thickness. At least one of an upper die (12) and a lower die (11) that are paired each other is moved in a direction in which the dies are combined together to form a main cavity part (MC) and a sub-cavity part (SC) communicating with the main cavity part (MC), and a gas is supplied into a metal pipe material between the upper die (12) and the lower die (11) to form a pipe part (100a) of a metal pipe (100) and a flange part (100b) of the metal pipe (100) in the main cavity part (MC) and the sub-cavity part (SC), respectively. Furthermore, by controlling a flange forming member (94) by the controller, the flange forming member (94) is allowed to advance in the sub-cavity part (SC), the formed flange part (100b) is crushed, and thus a flange part (100c) adjusted to be made thin is formed.
