2:1 Elliptical Heads

The 2:1 elliptical 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

90/17 Style 2:1 Elliptical Tank Heads

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

ASME 80/10 Tank Heads

With the ASME 80/10 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.

ASME Flanged & Dished Steel Tank Heads

The tolerances for these flanged and dished (F&D) 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.

The flanged and dished head necessitates a thicker cylinder than the corresponding cylinder. When pressure is mild and overall height is important, F&D heads are typically employed. 

Conical Tank Heads

Conical 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

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

Flanged Only Tank Heads

The flanged-only tank 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 IKR is a minimum of 3x the thickness, then they can be used for ASME usage.

Flared & Dished Steel Tank Heads

These flared and dished 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 Heads

Hemispherical (hemi) 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.

A hemi head is frequently employed in large-diameter or high-pressure applications when space is limited. A storage sphere is formed by putting two spherical heads back to back, which is the most efficient shape for pressurized storage.

Reversed Flanged & Dished Tank Heads

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.

Shallow Tank Heads

The radius of a shallow 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 & Dished Steel Tank Heads

Standard flanged and dished 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
  • 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 Cone Tank Heads

Toriconical cone 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.
