Understanding Industrial Autoclaves

Industrial autoclaves are industrial devices that are used to treat various components and materials at extremely high pressures and temperatures. Autoclaves are extremely useful in applications where chemical reactions need to be carried out under controlled conditions.

Industrial  Autoclaves

Design & Construction

In essence, autoclaves are another type of pressure vessel. As they apply extreme amounts of heat and pressure, the body of the vessel needs to be capable of withstanding the extreme conditions within the interior chamber. For this reason, high grade steel is the general material of choice when it comes to designing and constructing the autoclave. The vessel can be constructed with varying levels of thickness depending on the industry it will be used in, and the kind of components that will be placed within it.

One solution driven design factor is the fast opening door. When the heating process is at full pressure, the force upon the door is more than 1,000 tons. Thus, it protects engineers from the heat and pressure inside the chamber. It is also designed in a manner that an engineer can quickly and easily open it to remove the components without compromising on his safety. Various sources can be used to heat the autoclave. The most popular source is gas; however, there are electrically powered autoclaves as well.

Advantageous Features of Autoclaves

Industrial autoclaves are sought after by many industries; thanks to the following beneficial features:

  • They are manufactured adhering to the regulations laid down in ASME Section VIII, Division 1.
  • Numerous autoclaves comprise automatic hydraulic locking rings for sealing the chamber door. Usually, hydraulic locking doors are found on gas heated autoclaves, while pneumatic locking doors are found on electrically heated autoclaves.
  • Many manufacturers provide additional systems to support the autoclave. These include gas circulation nozzles for uniform temperatures, heating banks, as well as water cooling systems.
  • Several manufacturers also provide autoclaves with a five year warranty.


As one can imagine, autoclaves can be used in variety of applications to heat numerous components. A few typical application examples are given below.

  • Heat treating metal
  • Vulcanizing rubber
  • Composites manufacturing
  • Sterilization of medical instruments
  • Aerospace components manufacturing

As one can see, industrial autoclaves can prove to be indispensable products for a number of sectors.
