PRODUCT DETELS
Heads for steel pressure vessels, including boiler heads, can come in different shapes and configurations based on the specific requirements of the vessel. Here are some commonly used types:
Hemispherical Heads: Hemispherical heads have a shape similar to half of a sphere. They provide good strength and are often used in high-pressure applications. These heads distribute stress more evenly, reducing the potential for stress concentration.
Ellipsoidal Heads: Ellipsoidal heads have an elliptical shape and are commonly used in pressure vessels. They provide good strength and are easier to fabricate compared to hemispherical heads. The most common type is the 2:1 elliptical head, where the depth is half the diameter.
Torispherical Heads: Torispherical heads have a shape that is a combination of a toroidal and a spherical section. They are often used in pressure vessels and boilers, providing a more economical option compared to hemispherical heads. Torispherical heads have a knuckle radius (the transition area between the head and the straight flange) and a crown radius (the curved section of the head).
Spherical Crown Heads: Spherical crown heads are spherical in shape and are used in applications where a fully spherical head is required. These heads provide excellent strength and are often used in high-pressure or specialized vessels.
Flat Heads: Flat heads are simply flat plates used as end closures for some pressure vessels. They are less common in high-pressure applications but may be used in certain low-pressure vessels or tanks.
In terms of material, carbon steel is commonly used for pressure vessel heads due to its strength and affordability. The selection of the head type and material depends on factors such as the pressure rating, temperature, vessel geometry, and regulatory requirements.
Large-diameter elliptical heads, as you mentioned, refer to elliptical heads with larger dimensions. These heads are used in vessels or tanks with larger diameters, providing a smooth transition between the cylindrical section and the head. The specific dimensions and material selection for large-diameter elliptical heads depend on the requirements of the pressure vessel and the industry standards followed.
