We are the leading ASME code tank and code vessel supplier in the Midwest portion of the United States. We are capable of manufacturing code tanks and A.S.M.E. code tanks from carbon steel and alloy steel up to 100 tons.

We are fabricators and manufacturers of  custom and standard ASME (American Society of Mechanical Engineers) Code and Non-Code tanks, pressure vessels and components. We build closed containers that are designed to hold gases or liquids at a pressure substantially different from the ambient pressure. We are a custom fabricator of steel and alloy steel tank shells, separators, columns, heat exchangers, chambers, bladders, boiler steam drums, hydraulic and pneumatic accumulators, settler vessels, pulp and paper steaming vessels, pressurized storage tanks, cooker vessels (jacketed steam-cooker vessels), stripper columns and towers, vertical water softener vessels, pressure reactors, ASME separators, specialized heat exchangers, distillation towers, oil and gas refinery pressure vessels, flash tanks, rubber lined tanks, blow down tanks, compressed air vessels, mixing tanks, filter tanks, cyclone separators, autoclaves, API 650 units and deaerators.

We build code tanks and A.S.M.E. code tanks for applications such as food processing, oil and gas refining, chemical and petrochemical manufacturing, fertilizer mixing, pharmaceutical manufacturing, biotech, air & gas compression, adhesive manufacturing and paper processing industries.

When Halvorsen Company manufactures a tank or pressure vessel per the guidelines of ASME’s International Boiler and Pressure Vessel Code, the product is reviewed multiple times by certified inspectors. When we fabricate code tanks and code vessels we use pressure vessel-rated, parts and materials. We thoroughly review our calculations to verify the design requirements for cone stress, flanged dish heads, torispherical head walls and circumferential shells and ellipsoidal heads under internal pressure and many other components. Before we ship our code tanks, code vessels or pressure vessels to an oil refinery, chemical plant or manufacturing company, we conduct nondestructive examinations and tests.
