A pressure vessel, as a type of unit, is one of the most important components in industrial and petrochemical process plants. In the broad sense, the term pressure vessel encompasses a wide range of unit heat exchangers, reactors, storage vessels, columns, separation vessels, etc.

The pressure inside may be obtained from an external source or by the application of heat from a direct or indirect source, or any combination thereof.

Pressure vessels are used in a variety of applications in both industry and the private sector. They appear in these sectors as industrial compressed air receivers and domestic hot water storage tanks. Other examples of pressure vessels are diving cylinders, recompression chambers, distillation towers, pressure reactors, autoclaves, and many other vessels in mining operations, oil refineries and petrochemical plants, nuclear reactor vessels, submarine and space ship habitats, pneumatic reservoirs, hydraulic reservoirs under pressure, rail vehicle airbrake reservoirs, road vehicle airbrake reservoirs, and storage vessels for liquified gases such as ammonia, chlorine, and LPG (propane, butane).



Kennedy Tank can provide pressure vessels weighing over 400,000 pounds, with shell thicknesses of 2 inches and greater. Whether it is a simple air receiver, jacketed vessel or 250 foot tall column with trays, they can handle the toughest application.


  • Design pressures can range from 15 to 3,000 psig plus.

  • Their experienced engineers can customize a solution in a variety of alloys, including: Hastelloy, Inconel, Nickel, Nickel Alloy, Cladded Materials, 2205 Duplex, & All grades of Stainless Steel


Kennedy Tank has been designing and fabricating ASME pressure vessels for over 90 years! You can count on them to produce custom ASME pressure vessels to your unique requirements.

Capabilities range from small carbon steel air receivers to large diameter, high pressure applications in a variety of exotic metals and alloys.
Kennedy Tank has the experience, flexibility and fabrication capabilities to design and build engineering intensive ASME Pressure Vessels for such diverse industries as petrochemical, utilities, oil and gas exploration and pharmaceutical.
All ASME pressure vessels from Kennedy Tank are of the highest quality, both in construction and application.


Kennedy Tank provides jacketed pressure vessels with the full range of options, including half pipe jackets, dimpled jackets or conventional jackets.

In specifying jacketed pressure vessels, the choice of a jacket usually comes down to economy, weight and versatility of the heating or cooling requirement.
Heat transfer efficiency is another important consideration when deciding on which jacketed pressure vessel option best suits your needs.
Kennedy Tank has extensive experience with half pipe, dimpled or conventional jackets. As with all of their products, Kennedy Tank fabricates, inspects, tests and stamps its jacketed pressure vessels to ASME code and your unique requirements.


Distillation columns are widely used in the chemical process industries where large quantities of liquids have to be distilled. They separate liquid and vapor mixtures into component fractions of targeted purity, by the application and removal of heat.

Kennedy Tank provides an extensive range of materials and diameters for its distillation columns, based on the particular process parameters.
They also design our distillation columns for compatibility with wind and seismic requirements of the particular end user location.
experience also includes providing various distillation column internals, such as packing, trays and supports.


Kennedy Tank fabricates custom pressure vessels to the individual application needs of every customer. All vessels are conformity to ASME Code.

Custom pressure vessels are designed and fabricated to an array of considerations, including:

  • Size / Volume

  • Horizontal / Vertical orientation

  • Exotic Materials and Alloys

  • High Design Pressures & Temp

  • Jackets, including Half Pipe, Dimple or Conventional

  • Internal heating / cooling coils
