PURPOSE:To connect airtightly a molding vessel made of a flexible metal to be provided in a high-pressure vessel to a connecting pipe in the high-pressure vessel by using a metallic member which can join both vessels to each other to the connecting pipe for joining the above-mentioned two vessels. CONSTITUTION:The molding vessel 2 made of the flexible metal is attached via the connecting pipe 3 to the inside of the high-pressure vessel constituted of a high-pressure cylinder made of iron or ferrous alloy and cap thereof. After heated fluid 6 is supplied to the inside of the vessel 1, the fluid is pressurized to an ultra-high pressure to pressurize and mold powder 7 packed preliminarily into the vessel 2. The pipe 3 is airtightly connected by welding, etc. to the vessels 1, 2 and the gaseous molecules generated during the molding of the powder 7 are evacuated by a vacuum evacuation device 12. One end and the other end of the pipe 3 are respectively formed of SUS and Al members 8, 9 and are welded to the vessels 1, 2 and further Ni and Cu members 10, 11 are interposed between the two members if the vessel 2 is made of Al. These members are press-welded to join integrally the vessels 1 and 2.
