Reactor Pressure Vessels Built to Your Specifications


Reactors are vessels that are designed to contain chemical reactions related to distillation, extractions, and post-processing. Depending upon the intended application and industry, they can be constructed in various shapes, sizes, and forms, and can be made with numerous materials, including stainless steel and hastelloy. At American Alloy Fabricators, we design and fabricate reactors to our clients’ specifications while ensuring compliance with strict ASME requirements.

Industries that routinely use reactors include, but aren’t limited to:

  • Cosmetics
  • Fermentation
  • Food processing
  • Medical
  • Pharmaceutical
  • Chemical

Jacketed Reactors

half-pipe-jacketed-reactorWhen accurate temperature control is required, jacketed reactors provide the optimal solution. The jackets create a pocket around the reactor that allows fluid to circulate to either heat or cool the container. This design ensures uniform heat exchange between the circulating fluid, the walls of the vessel, and the processed contents.

Different types of jacketed reactors include:

Conventional Jacketed Reactors

Conventional or open jacket reactors have an external shell that surrounds the primary vessel to provide a space for heat transfer fluid. This style of reactor offers the most coverage; however, it is often the thickest and heaviest jacket option, as the pressure of the jacket is applied as external pressure to the inner vessel. American Alloy Fabricators manufactures our conventional jacketed pressure reactor with a spiral-formed internal baffle that guides the heating fluid around the tank.

Half-Pipe Jacket Reactors

A half-pipe jacketed reactor has piping that is welded to the outside of the tank. They allow high flow rates and employ hot oil and other media, making them ideal for high pressure and temperature applications. To increase fluid velocity and minimize pressure, we use a 180° design. The continuous coil formation of our half-pipe reactor can be wrapped in one or more zones.

Dimple Jacketed Reactors

The surface is embedded with a series of equally spaced dimples that make the tank lightweight and cost-effective. While not appropriate for thermal shocking or extreme temperature changes, this type of reactor pressure vessel is a good choice for steam heating or water cooling. American Alloy Fabricators ensures a secure fit by rolling our dimpled jacket around the tank then plug welding the dimples to the vessel.
