Custom Stainless Steel Tanks and Vessels

Ramco Fabricators builds custom stainless steel tanks and pressure vessels in Colfax, North Carolina, just west of Greensboro. Stainless and carbon steel are the two materials we work every day: we roll stainless plate up to 1-1/4 inch thick on our plate rolls, weld the long seams by submerged arc with procedures qualified to ASME Section IX, and build everything from simple storage tanks to intricate process and mix tanks and ASME Code vessels, up to 14 feet 8 inches in diameter and 100 feet long.

Process and Mix Tanks

Stainless is the material of choice when the product has to stay clean or the tank has to stand up to something corrosive, and that describes most of the process and mix tanks we build. We build them in varying complexities, from a simple stainless storage tank to intricate process tanks for large corporations, with the nozzles, manways, and supports your process needs, and we help with the layout so the tank fits the plant rather than the other way around.

Stainless Pressure Vessels

When your process calls for stainless, we build ASME Section VIII Division 1 vessels in it the same way we build them in carbon steel: designed by our Engineering department, "U" stamped, and registered with the National Board. Sterilizers, autoclaves, mix tanks, jacketed vessels, and air receivers are all on the list of Code vessels we have built, and we can quote any of them in stainless.

Rolling and Welding Stainless

Stainless takes more care than carbon steel. It work-hardens as it is formed, it holds heat differently when it is welded, and it has to be kept clean of carbon steel contamination the whole way through the shop. Our plate rolls take stainless to the same 1-1/4 inch thickness as carbon steel, our submerged arc procedures are qualified for it, and our rolling department rolls stainless structural shapes for stiffener rings and supports. If you only need stainless plate rolled or a stainless shell welded for your own shop, we are glad to do that too!

Choosing the Material

Tell us what the tank will hold, how hot it will get, and how it will be cleaned, and we will help you decide between carbon steel and stainless and quote the stainless grade your specification calls for. Where only the wetted surfaces need to be stainless, a carbon steel tank with stainless internals can save real money, and we will tell you when that is an option.

Who We Build For

Our stainless tanks and vessels go to food processors, rendering plants, and chemical and industrial plants. Most of the contractors and engineers who order them are in North Carolina, from the Piedmont Triad to Raleigh and Charlotte, and up through Virginia, but the tanks themselves end up at facilities all over the country, and we help arrange the freight.

Frequently Asked Questions

Which stainless grades do you work with?

We quote the grade your specification calls for. If you do not have a specification yet, tell us what the tank will hold and how it will be used and we will help you choose.

How thick a stainless plate can you roll?

Up to 1-1/4 inch thick and 10 feet wide, down to a 24 inch inside diameter, the same as carbon steel. See the plate rolling page for the full table.

Do you build ASME Code vessels in stainless?

Yes! Our "U" stamp covers stainless vessels the same as carbon steel ones, and every vessel we build is registered with the National Board.

Can you mix carbon and stainless in one tank?

Yes. Where only the wetted parts need to be stainless, a carbon steel tank with stainless internals or a stainless liner can do the job for less. We will tell you when that makes sense for your application.

We will gladly prepare a customized quote for you.
