An ASME dished end is a pressure vessel head that conforms to the standards set by the American Society of Mechanical Engineers (ASME), ensuring that it meets stringent quality and safety requirements for use in various industrial applications. The ASME code outlines different types of dished ends, such as ellipsoidal heads, torispherical heads (commonly referred to as ASME F&D heads), hemispherical heads, and more. Each type possesses distinct advantages and is selected based on criteria like pressure capacity, volume requirements, and material characteristics.
