Why Choose AEFab for Steel Tanks and Vessels
As a steel tank manufacturer and fabricator, AEFab builds and tests everything at its own works. Plate becomes a finished, code-compliant tank or vessel without passing through a middleman.
What Are Steel Tanks and Vessels?
Steel tanks and vessels are fabricated steel containers that store or process liquids, gases and solids. A tank usually holds its contents at atmospheric pressure, while a vessel is built to hold pressure, vacuum or a process duty. Tank fabrication turns steel plate into these containers by rolling, forming, welding, testing and finishing to the relevant code.
We fabricate the full range, from a single atmospheric storage tank to a complex jacketed pressure vessel with internal coils, matching the material and the code to each duty.
Steel Tank Fabrication in Any Material
We are a steel tank manufacturer across materials, not one grade.
Stainless Steel
SS 304, 304L, 316 and 316L for hygienic and corrosion-resistant duties. See the stainless steel grades reference for material selection.
Carbon and Mild Steel
Carbon steel to IS 2062, with boiler-quality plate to IS 2002 and the SA 516 range for pressure duty. This covers mild steel storage tanks and structural tankwork.
Tanks and vessels are part of AEFab's wider steel fabrication capability.
Steel Tanks and Vessels We Fabricate
Six families, one works. Each is engineered to its duty, and each has a detailed page.
Stainless Steel Tanks and Vessels
Storage and process tanks in SS 304, 304L, 316 and 316L, for duties where cleanliness and corrosion resistance matter. We build single-wall atmospheric tanks through to jacketed and insulated vessels, and fit internals such as pipe coils, limpet coils, dip tubes, baffles, ladders and dividers. Typical uses are chemical, pharmaceutical and food process storage and mixing.

Hot Water and Water Storage Tanks
Insulated stainless steel hot water and water storage tanks in SS 304, sized to hold peak demand while limiting heat loss. The corrosion-resistant build suits potable water, process hot water and utility storage. Supplied vertical or horizontal, with the fittings and supports to suit your installation.

Pressure Vessels
Vessels built to hold internal pressure or vacuum, in carbon steel or stainless steel, to ASME Sec VIII and IS 2825. Each vessel is engineered to its design pressure and temperature, with radiography and hydro-testing carried out against the Quality Assurance Plan. Horizontal or vertical, and jacketed where the process calls for it.

Air Receivers
Pressure tanks that store compressed air, steady the system pressure and cut compressor cycling. Built as pressure vessels for the working pressure of your compressed-air system, in vertical or horizontal form, with the usual mountings, drain and safety fittings. Sized to your compressor and air demand.

Agitators and Mixing Tanks
Tanks fitted with agitators for blending, dissolving, suspension and heat transfer. We match the impeller type, speed and materials to your viscosity and duty, in stainless or carbon steel, with a jacket or coils added where the mix needs heating or cooling. Built as a complete mixing tank or as an agitator for your existing vessel.

Industrial Chemical Reactors
Jacketed, agitated reaction vessels for process reactions that need controlled heating, cooling and mixing. Built in stainless or carbon steel with limpet or conventional jackets, internal coils and agitation, and rated to ASME Sec VIII and IS 2825 for pressure duty. Configured around your reaction, pressure and temperature.
