Fabrication Construction Maintenance

Enerfab’s mission is to be the most dependable and trusted source for our customers’ construction, specialty fabrication and maintenance contractor needs by demonstrating excellence through execution. We do this through our expertise and personal commitment to doing whatever it takes to deliver on our promises.


Enerfab’s skilled craftsmen have produced the highest-quality tanks, pressure vessels, pipe spools, and heads since 1901. Our customer-centric focus and structure means your project is delivered consistently on time and on budget. We continuously challenge ourselves and our customers to embrace new ideas using state-of-the-art technology and proprietary processes. We treat every customer as a partner and stand behind our work no matter what.

Our innovative way of thinking sets us apart:


Experts in Welding

Having performed more than 1,000 custom weld procedures, our skilled workers utilize decades of experience to identify the right process to control quality and the delivery schedule of your project.


In-house Machining

Customers often bring us complicated projects that include intricate and precise tolerances. We utilize high-tech CNC machining centers to produce attachments and internal parts, such as tube sheets for heat exchangers and body flanges to manage the final cost of your project.



We have the capability to produce this glass-like finish for customers, especially those in the chemical industry, making it possible for easier product draining and cleaning. Ultimately, this reduces your production down-time.


Proprietary Half-pipe Forming

We’ve developed a proprietary process for half-pipe jacketing, utilizing a continuous coil. This process results in fewer welds on the half pipe, fewer butt welds, a full-penetration weld, and fewer fatigue points, therefore, extending your equipment’s lifespan.

API Storage Tanks

API Storage Tanks


Built to API 650 and API 620 standards, we can fabricate tanks to accommodate more than 2.2 million gallons. Our in-house field erection and fabrication teams can develop a solution for your specific tank needs. Types of tanks we manufacture include:

  • API Storage Tanks (Aseptic, Water, and Silo)
  • Field Erected
  • Polished
  • Silo
  • Stainless Steel
  • Welding-insulated Casing

Vessels, Reactors & Columns/Towers



Our team can shop or field construct your ASME pressure vessels, fabricating them to ASME code for both Div I and Div II standards.



Enerfab provides chemical reactors with jacketing, including half pipe. We can also utilize cladding to meet customer budgets while achieving ideal thicknesses and alloy content.



Regardless of the size, our craftsmen can shop or field fabricate process columns and process towers for a variety of industries to meet challenging customer specifications. Enerfab specializes in one-piece fabrication and delivery over-the-road or by barge.



Fabrication for the food and beverage industry has been a part of Enerfab’s offerings since our founding. Fermenting tanks can be shop or field fabricated to meet your needs.



Spheres can be custom constructed to your ASME code requirements and include self-supporting leg systems.
