The 2:1 elliptical tank heads are used extensively for liquefied petroleum gas tanks, air receivers and other pressure vessels. For this type of head, the depth of tank head is one-quarter of the vessel's internal diameter. With its reduced metal thickness, elliptical tank heads offer an economic solution for medium-pressure tanks. These can be custom formed from:
Carbon steel
Stainless steel
Other ferrous and non-ferrous metals and alloys

The 90/17 style head is an acceptable approximation of a 2:1 Elliptical per ASME Section VIII Div. 1 UG 32.

With the ASME 80/10 tank head, the inside dish radius is 80% of the diameter and the inside knuckle radius is 10% of the diameter. Our 80/10 tank heads meet all the requirements of the ASME pressure vessel code.

The tolerances for these flanged and dished tank heads comply with ASME requirements. The tank heads may be custom formed from:
Carbon steel
Stainless steel
Other ferrous and non-ferrous metals and alloys
The inside dish radius is typically 100% of the diameter, and the inside knuckle radius at least 6% of the diameter.

Conical tank heads are often used for process equipment, including evaporators, spray driers, crystallizers and settling tanks. These types of heads allow the accumulation and removal of solids at the bottom of the head. Conical sections can be formed on rolling equipment that is used to roll cylindrical shells.

Dished-only tank heads are used in a variety of applications, including pressure vessels, reinforcement pads, domed roofs for large storage tanks, vacuum chambers, wear plates and liners. These tank heads are made from:
Carbon steel
Stainless steel
Aluminum
Other ferrous and non-ferrous alloys

The flanged only heads are often used for liquid storage, especially gas and petroleum products. They are a flat head with a knuckle radius. Typically, they are used for non-code applications, but if the ICR is a minimum of 3x the thickness, then they can be used for ASME usage.

These tank heads, sometimes called hat-heads, are used in industrial non-code applications, including bolt-on covers, hinged covers, tank ends and baffles. They are formed from:
Carbon steel
Stainless steel
Aluminum
Other ferrous and non-ferrous alloys

Hemispherical tank heads are the strongest of the formed heads. They can resist about twice the pressure rating of an elliptical dished head or cylindrical shell of the same thickness and diameter. Due to their strength and resistance, these tank heads are widely used for the storage of liquids and gasses under pressure.

Reversed flanged and dished tank heads are comprised of both a concave dish radius and a knuckle radius. They are often used on the ends of vessels that face against a plane surface, such as steel vessels on concrete slabs. These tank heads offer the advantage of a load-bearing surface as well as the additional strength from dishing.

The radius of a shallow tank head is equal to or less than the outside diameter. These heads are fabricated with the same outside diameter as the nominal diameter. Shallow tank heads are primarily used for horizontal storage tanks and are not permitted in vessels that must meet pressure-code requirements.

Standard flanged and dished tank heads are used for liquid storage tanks in situations where ASME code requirements aren't applicable. The tank heads may be formed from:
Carbon steel
Stainless steel/p>
Aluminum
Other ferrous and non-ferrous alloys
The inside dish radius is typically 100% of the diameter, and the inside knuckle radius is usually three times the material thickness.

Toriconical tank heads are different from conical heads in that they have a radius at the flanged head. They can also be formed from flat plates. While more expensive than conical heads, toriconical heads uniformly distribute localized stresses and reduces them in the area near where the cone and the shell join together. Toriconical tank heads are often used in hoppers and towers.


Stock 2:1 Elliptical tank heads offer the same advantages and usages of 2:1 Elliptical tank heads, including an economic solution for medium-pressure tanks. Brighton Tru-Edge's standard stock sizes offer easier ordering and faster delivery time.

At Brighton Tru-Edge, we stock stainless steel heads in both ASME 2:1 Elliptical and ASME Flanged & Dished styles. Stock heads are offered in SA240 304/304L dual-certified and SA240 316/316L dual-certified, and they are formed without a center hole.
We have a variety of specific sizes. Stock tank heads offer the benefit of immediate shipment to meet even the strictest project deadline.

Brighton Tru-Edge fabricates segmented domes, hemispheres, 2:1 Elliptical, and ASME Flanged & Dished heads when projects call for larger pressing capacities. With most of these segmented heads, we fabricate large dollar caps and segments allowing for minimized welding while assembling in the field.







Brighton Tru-Edge can provide welded plate in a variety of widths and thicknesses to support your cylinder and fabrication needs. The plates can be provided with X-ray and U2-A reports when required.

Cylinders can be fabricated from stainless steel, carbon, nickel alloys, clad, aluminum, copper and other exotic materials. Brighton has the capacity to roll plates up to 16' wide in thicknesses of 1.25" thick mild steel, or 1" thick stainless steel. For heavier thicknesses, our Natchez facility can roll 10' wide by 2” thick shells. The fully welded cylinders can be provided with x-ray, dye check and code paperwork if required.
When requesting a quote you will provide us with Material, Polish (if required), Thickness, Diameter and Length of Cylinder.
