<p>A hot isostatic pressing apparatus comprising a pressure vessel (5), heater (9) and heat-insulating layer (10, 201 interposed between the wall of the pressure vessel (5) and the heater (9). The heat-insulating layer (10, 20) is formed of a least two layers, ie an inner layer (10) and an outer layer (20). The inner layer (10) surrounds an object (M), which is under treatment, and the heater (9). The inner layer (10) is loadable into and unloadable from the pressure vessel (5) together with the object (M) and heater (9) while maintaining a chamber, which is surrounded by the inner layer (10), hermetically isolated from the surrounding atmosphere. However, the outer layer (20) remains within the pressure vessel (5). When the hot isostatic pressing apparatus is incorporated in a modular HIP system, the cooling time is considerable shortened and the efficiency of the HIP treatment is hence improved to a considerable extent.</p> |
