Ellipsoidal Head, Hemispherical Head, and Torispherical Head are three common types of ASME Pressure Vessel Dished Heads. This is also known as a 2:1 elliptical head. It is cost-effective due to its compact design, with the height being one-quarter of the diameter. The radius changes between the major and minor axes, making it suitable for various pressure applications. A hemisphere is the most efficient shape for a head because it evenly distributes internal pressure across the surface. The radius of the head matches that of the cylindrical part of the vessel, ensuring structural integrity and strength. These heads feature a dish with a fixed radius (CR) and a knuckle that transitions from the cylinder to the dish. The knuckle has a toroidal shape, which allows for better stress distribution and is commonly used in industrial pressure vessels. DISH HEAD ELLIPSOIDAL HEAD Materials & Types Company Information The company employs 135 staff members, including 33 engineering technicians, 5 senior professionals, and 25 middle and senior-level technical workers.

Most Common Types of Torispherical Heads
This is a type of torispherical head where the dish has a radius equal to the diameter of the attached cylinder. The knuckle radius is typically one-tenth of the cylinder's diameter, providing a balanced design for pressure distribution.
Also referred to as a semi-ellipsoidal head, this type features a dish radius of approximately 90.45% of the cylinder’s diameter (ICR = 0.9045 x OD). The knuckle radius is about 17.29% of the cylinder’s diameter (IKR = 0.1729 x OD), offering a smooth transition and high strength.
