ASME Code pressure vessel fabrication, installation, and repair

U.S. Pressure Vessels builds custom ASME pressure vessels and pressure piping systems. Our team is committed to providing products that meet or exceed expectations for performance and reliability at the most reasonable cost possible.


At US Pressure Vessels, we design and fabricate new carbon steel, stainless steel or special alloy vessels to customer specifications. We work with our customers to design and build large or small, single or multiple customized pressure vessels to fit your design requirements. We can also alter or repair pressure vessels in the field or in our shop.

The US Pressure Vessels engineering team prepares Code design calculations and detailed CAD fabrication drawings to your specifications. Our ASME accreditation allows the fabrication of Power Piping to the ASME B31.1 Power Piping Code.


US Pressure Vessels uses the rules of the National Board Inspection Code to perform any alterations or repairs to your pressure equipment. Now you can be confident that you are getting the best there is!

Our National Board “R” Symbol Stamp allows us to alter or modify your existing pressure equipment to suit changing operational needs. We can design, fabricate and install attachments or perform re-rating calculations based on existing conditions. Using our design and fabrication team you can modernize your equipment without capital outlay.

Complete or Partial Rebuilds
At your request, we will evaluate the condition of your mechanical systems, and help you determine the work required to return your pressure equipment to original design pressure or capacity. We can then provide the most cost-effective repairs to make your equipment perform like new. You can now avoid costly and time-consuming replacement of your pressure equipment by having U.S. Pressure Vessels return your equipment to like-new condition.


While ASME Code pressure equipment is our principle business, we can manufacture pressure vessels and non-code fluid storage tanks in many innovative configurations.

Our 44,000 square foot shop and twelve bridge cranes allow us the flexibility to fabricate large multi-chambered vessels and retorts, small individual pressure vessels, or production runs of multiple units. We can fabricate not only your pressure tanks, but also the piping, structures, and mechanical systems required for their operation. Our shop equipment includes custom plate rolling, shearing and bending, two high-definition CNC-controlled plasma metal cutting machines and multiple welding systems.
