Vessel Heads and Cones

Pressure Vessel Heads

Antonius makes different kinds of pressure vessel heads, and we make these vessel heads in different shapes and forms. Our production facilities are equipped for a wide range of sizes and thicknesses, precisely matched to the desired product. Of course, depending on the type of material.

Working with Antonius

We operate worldwide on five continents from our homebase in Maasbracht, the Netherlands, where our production facility is located. Our primary markets include Oil&Gas, Chemical Process industry, Power Generation, Pulp&Paper, and Food. With a team of 55 skilled professionals, we possess extensive knowledge and expertise in forming carbon steels, stainless steels, and other special materials. Our craftsmanship sets us apart and is why customers and engineering firms approach Antonius at an early stage.

The specifications we do vary considerably per market, country and customer. We have expertise in design codes such as ASME, EN 13445, AD-2000, Norsok, and many others. With our comprehensive understanding of various material grades, highly skilled welders, and specialized machinery, we can manufacture high-quality products in all standard and special material grades and sizes. We are convinced that we deliver products of high quality and we are always trying to reach our customers requirements.

Thorispherical head

The Torispherical head has different kind of shaping’s. These are mostly applied at lower to medium pressure vessels, the latter ofter at larger diameters such as for beer tanks. We can produce these heads in a diameter ranging from 200 up to 10,500 mm and in thicknesses ranging from 3 to 120 mm.

Korbbogen-head

The Korbbogen-heads are very similar to the elliptical 2:1 head. We can produce these heads in a diameter ranging from 200 to 10,500 mm and in thicknesses ranging from 3 to 120 mm.

Elleptical head

The Ellipsoidal heads are similar to the Korbbogen-heads, simple said the Korbbogen heads are the European Eleptical heads. We produce these heads in a diameter ranging from 2000 to 10,500 mm and in thickness ranging from 3 to 120 mm.

Flat head

Flat Heads are recommended to be ideal for nu pressure applications. The flatheads are with flat surfaces which make them perfect for installations that require flat inside surfaces. However, when used for pressure applications these pressure vessel heads may turn out to be more costly than other heads. We produce these heads in variable diameters ranging from 200 to 10000 mm and in thickness ranging from 3 to 50 mm.

Hemispherical heads

Hemispherical heads possess a radial structure in which the depth of the head is half of its diameter. These storage heads are composed of two pressure heads that are positioned in a back-to-back manner, giving rise to a spherical shape that facilitates the high-pressure storage of materials with ease. In contrast to shells, hemispherical heads have thinner heads and utilize a standard 3:1 code that tapers during the transition. Welded sheets are predominantly used in the construction of hemispherical heads, rather than flat sheets, as seen in other types of heads. Consequently, hemispherical heads are the thinnest but also one of the most expensive head types. Hemispherical heads are ideal for applications that require large-diameter vessels or high-pressure storage.

We can produce these heads in a diameter ranging from 200 to 1800 mm in one piece and in thicknesses ranging from 3 to 120 mm. Bigger diameters will be made from segments with unlimited dimensions.

Segmented head

A head that is segmented or segmental can take on various shapes such as 2:1 Elliptical heads, 1.9:1 Elliptical heads, Korbbogen heads, or Kopperhead. If the head is too large to be formed by standard tooling or by cold pressing and spinning, it must be manufactured using a crown and petal method. The individual segments or petals are created by (hot/cold) pressing them using specially designed tooling. The central cap or crown can be formed using conventional (hot/cold) pressing methods. The number of segments and the diameter of the central cap are determined by the available material sizes, efficient material nesting, and the maximum tooling size.

Special 3D shaped parts

With years of experience working with a variety of materials and careful tool selection, we can consistently produce pressed parts that meet the necessary requirements.
Antonius is highly regarded for their expertise in producing custom vessel heads in a range of materials and shapes. Our reputation is built on the knowledge, experience, and craftsmanship that we bring to all-metal shapes and solutions.
Our team of 65 professionals has extensive knowledge and expertise in working with carbon steels, stainless steels, nickel and nickel alloys, aluminum and aluminum alloys, copper and copper alloys, titanium and its alloys, zirconium, and other special materials. Our exceptional craftsmanship is a primary reason why our customers choose to work with Antonius early in the process.
