Commonly used for ASME pressure vessels, these torispherical heads have a crown radius equal to the outside diameter of the head (=), and a knuckle radius equal to 6% of the outside diameter (=). The ASME design code does not allow the knuckle radius to be any less than 6% of the outside diameter.

Torispherical heads provide excellent pressure resistance, uniform stress distribution, and increased volume capacity compared to ellipsoidal heads. They are versatile and can be fabricated with different knuckle and crown radius ratios to meet specific design requirements.

2019年3月7日 · Torispherical Head. The torispherical dished heads are used for vertical or horizontal pressure vessel or horizontal pressure vessel in the pressure range from 0.1 N/mm2 or 1.5 N/mm2 These type of heads are shaped by using two radii : the dish radius or crown radius (Rc) & inner corner radius or knuckle radius (ric) Applicable for Low Thick Vessel

Below we'll explain how we used it to find out the inside volume and weight of the torispherical head used in the Shell & Head Design module.

2023年12月12日 · One commonly used type of head is the torispherical head, which includes the ASME flanged and dished head and the 10% dished head. These heads have specific geometric dimensions that need to be considered during the design and fabrication process.

2023年12月12日 · Torispherical heads represent a specific and widely used type of closure head in pressure vessel design. Characterized by a shape resembling a torus or a segment of a sphere, these heads offer a balance between structural efficiency and ease of fabrication.
