ABSTRACT:
A hot isostatic pressing apparatus which includes a pressure vessel, a heater and a heat-insulating layer interposed between the pressure vessel and heater. The heat-insulating layer is formed of at least two layers, i.e., an inner layer and outer layer. The inner layer embraces an object, which is under treatment, and the heater. The inner layer is loadable in and unloadable from the pressure vessel together with the object and heater while maintaining a space, which is embraced by the inner layer, in a state hermetically isolated from the surrounding atmosphere. However, the outer layer is held within the pressure vessel. When the hot isostatic pressing apparatus is incorporated in a modular HIP system, the cooling time is considerably shortened and the efficiency of the HIP treatment is hence improved to a considerable extent.
