Segmented tank heads are a type of tank head that consists of multiple segments welded together to form a curved shape. They are often used for large diameter or high pressure vessels that require a custom shape or size. Segmented tank heads can be divided into two categories: crown and petal heads, and ASME code heads.
Crown and petal heads are made of flat plates that are cut into wedge-shaped pieces and then welded together along the edges. The number of petals depends on the desired diameter and curvature of the head. Crown and petal heads are suitable for low to medium pressure applications, such as water storage, chemical, or oil tanks.
ASME code heads are segmented tank heads that comply with the standards and specifications of the American Society of Mechanical Engineers (ASME). They are designed to withstand higher pressures and temperatures than crown and petal heads. ASME code heads are usually made of thicker plates and have more complex geometries, such as ellipsoidal, torispherical, or hemispherical shapes.
