PURPOSE:To increase the reliability of the various tests by constituting the titled autoclave of a thin-walled inside vessel consisting of a specified material, a pressure-resistant thick-walled outside vessel, a heat insulator packed in a space between the inside and outside vessels and the means introducing and discharging a noncrossive gas. CONSTITUTION:Two or more kinds of materials 1 for the testing or to be treated are packed in the inside of the inside vessel 2 of an autoclave and closed and the temp. thereof is risen with a heating means 10. At this time, a gas (a) having the pressure P' approximately close to the pressure P of the inside of the inside vessel 2 is fed under pressure to a space 4 between the inside and outside vessels 2, 3 as the pressure P is risen with the thermal expansion. Therefore even if the materials 1 incorporated in the inside vessel 2 reaches the testing temp. or the treating temp. and the pressure of the inside reaches the substantial high pressure Pmax, the high pressure Pmax' balancing with the pressure Pmax is acted on the outside of the inside vessel 2. |
