Autoclave industrial Wikipedia. Industrial autoclaves are pressure vessels used to process parts and materials which require exposure to elevated pressure and temperature. The manufacture of high performance components from advanced composites often requires autoclave processing. Industrial autoclaves used in the aerospace industry. The autoclave on left is gas fired the machine on right is electrically heated. At full pressure, the force acting against the door of the grey machine is over one thousand tons.

Principle of operationedit. Small autoclave with electric heat, used in the manufacture of advanced composite parts. This autoclave features a low cost manual latch door design. Note the removable works on a trolley back end. An autoclave applies both heat and pressure to the workload placed inside of it.

Those pressurized with steam process workloads which can withstand exposure to water, while circulating heated gas provides greater flexibility and control of the heating atmosphere. Processing by autoclave is far more costly than oven heating and is therefore generally used only when isostatic pressure must be applied to a workload of comparatively complex shape. For smaller flat parts, heated presses offer much shorter cycle times. In other applications, the pressure is not required by the process but is integral with the use of steam, since steam temperature is directly related to steam pressure. Rubber vulcanizing exemplifies this category of autoclaving.

For exceptional requirements, such as the curing of ablative composite rocket engine nozzles and missile nosecones, a hydroclave12 can be used, but this entails extremely high equipment costs and elevated risks in operation. The hydroclave is pressurized with water 3 the pressure keeps the water in liquid phase despite the high temperature. The key component of the industrial autoclave is the fast opening door this is also the critical component in cost of autoclave construction. On one hand, the operator must be able to open and close the door quickly and easily on the other, the door must satisfy stringent safety requirements. Such is the quality of autoclave door design that the US experiences as few as an estimated five or six autoclave failures annually. Autoclave design is driven by various safety standards, foremost among which is the ASME Pressure Vessel Code. While most nations use the ASME code, some have developed their own.

Design and constructioneditPressure vesseleditPressure vessel design involves Barlows formula, used to calculate the required wall thickness. However, the design of a complex pressure containment system involves much more than the application of this formula. For almost all pressure vessels, the ASME code stipulates the requirements for design and testing. Prior to delivery, the pressure vessel is hydrostatically tested at 1. ASME code inspector. It is filled with water, and a small pump raises the pressure to the necessary test value, at which it is held for a specified time 3. ASME code. The inspector checks for leaks as well as evidence of flaws or inadequacies in the welding. The design of small autoclaves need not take into consideration the possibility of drawing a vacuum inside the pressure vessel, but this assumption must not be made in larger ones.

The Global Positioning System GPS, originally Navstar GPS, is a spacebased radionavigation system owned by the United States government and operated by the United. Steam autoclaves, for example, can be exposed to an internal vacuum if the steam fully condenses while the vessel remains sealed. Although external pressure cannot exceed one atmosphere,5 that can suffice to collapse the vessel in some cases. Thus, stiffening may be required. In unusual situations, the autoclave itself might have to be square or rectangular instead of round, or it might be vertical instead of horizontal. If the autoclave is unusually large, it may have to be set into an excavation in the floor if there is to be floor level loading, as is generally the case. MaterialseditThe selection of the materials from which the autoclave is fabricated turns entirely upon the application. For steam autoclaves, carbon steel is used, but a corrosion allowance is added to the calculated thickness. This accommodates the rusting that occurs with repeated cycles of exposure to steam, water, and air. Implicit in this is the need to monitor the loss of metal and decommission the vessel when excessive thickness loss has occurred. For temperatures of up to 6. F 3. 43 C, no adjustment needs to be made in calculating vessel wall thickness. Above this temperature, the allowable stress is derated. Above 7. 50 F 3. C, high temperature alloys are used. The rated temperature, which is stamped on the vessels data plate, applies to the vessel wall itself, not to the gas circulating in the autoclave. This is relevant when internal insulation is used to circulate air or gas at a temperature beyond the rating of the vessel. Although the design engineer can use the material of his or her own choice, the normal selection is SA5. Grade 7. 0 PVQ Pressure Vessel Quality carbon steel. This steel is particularly well suited for use in pressure vessels by virtue of having an exceptional spread between its comparatively low yield strength of 3. Elongation in 2 inch thick 5. This means that the metal stretches considerably under over stress before failing. In the event of excessive pressure, parts will deform before breaking, causing a gradual rather than a catastrophic loss of sealing. This loss of pressure then acts to relieve the critical overload on the pressure vessel structure. This failure mode presumes the absence of significant cracks in the over stressed metal. Because this grade is used in pressure vessels, it is available in thickness variations of a sixteenth of an inch as well as large plate sizes. It is readily welded and is fully machinable. The pressure vessel specification will include both the highest and the lowest temperatures to which the vessel shell is exposed. Since steel properties change as the metal becomes colder, the vessel will be stamped for an MDMT7 of 2. F unless the user requires lower. Customarily, the metal thickness is driven by the code requirements relating to visual inspection. Thinner metal can be used, providing the welds are radiographed. This saves cost when the metal is not SA5. Autoclave used to manufacture F 1. Electric heat, simple door, automated control. Of the entire machine, the costliest depending on the size of the autoclave and most important single piece of hardware is the fast opening door. It must be of full diameter to allow access to the working space, seal tightly against rated pressure at the highest shell temperature,8 operate readily and quickly, and comply with the same safety code that governs the rest of the pressure vessel. Of all safety related concerns, the most critical are those which relate to the doors operation. There are several types of fast opening doors commonly used.
