An interlocking device for a HIP equipment that prevents possible damage to the HIP equipment arising from use of a furnace or processing gas in error and can control the oxygen concentration and pressure within the HIP equipment. The device includes a sensor for detecting a concentration of oxygen in the processing gas in a processing gas pipe system. If the sensor detects an excessively high oxygen concentration, a supply side interlocking mechanism closes a valve for the pipe system and disconnects a power source for a furnace in a high pressure vessel. A flow switch is connected to a safety pipe system having a safety device, and a thermocouple is provided for each of the safety and processing gas pipe systems and a relief pipe system. When the flow switch detects processing gas being spouted from the safety pipe system and/or when one of the temperature signals from the thermocouples exceeds a preset value, a relief side interlocking mechanism closes the processing gas pipe system, opens the relief pipe system, stops a gas compressor and disconnects the power source.

Interlocking device for hot isostatic pressurizing equipment

A press device which is reduced in overall height thereof and in deformation of a press frame and can sufficiently support an eccentric load thereto. The press device comprises a press force generating unit disposed in a press frame and including a lid member secured to the press frame, a cross head having a cylinder chamber in which the lid member is fitted for axial sliding movement and having a blank holder at an end face thereof remote from the lid member, and a pressurizing member fitted for axial sliding movement in a portion of the cylinder chamber remote from the lid member. A shaping element is disposed in the press frame in an opposing relationship to the press force generating unit and has a shaping portion in which the pressurizing member is fitted. A guide element is connected to the cross head for guiding the cross head for axial sliding movement, and a cross head actuating device is connected to the cross head for axially moving the cross head under the guidance of the guide element independently of the pressurizing member.
