304L torispherical dish ends are a type of vessel closure typically used in pressure vessels or tanks . Made from 304L stainless steel , these dish ends have a toroidal shape with a spherical crown and a cylindrical knuckle .
The term “304L” refers to the specific grade of stainless steel used , which is a low – carbon variant of 304 stainless steel . This grade offers excellent corrosion resistance , making it suitable for various applications in industries such as chemical processing , food and beverage , pharmaceuticals , and more .
Torispherical dish ends are commonly used because their design provides structural integrity while minimizing stress concentrations . The spherical crown distributes pressure evenly , reducing the risk of failure under high – pressure conditions . The cylindrical knuckle helps to transition smoothly between the crown and the straight sidewall of the vessel .
