ASME SA516 GR.70 Dish Head Hemispherical Elliptical Dished End Oil Gas Tank Head
PRODUCT DETELS
The ASME SA516 GR.70 refers to a specific grade of carbon steel plate that is commonly used for pressure vessel applications. It is a normalized steel with excellent weldability and notch toughness, making it suitable for various industrial environments.
Dish Head, Hemispherical, and Elliptical Dished End are different shapes of vessel heads used to close the ends of pressure vessels or tanks. Let's discuss each one:
Dish Head: A dish head, also known as a torispherical head, has a curved shape resembling a portion of a sphere. It is commonly used in pressure vessels and tanks. The dish head provides structural strength and helps distribute the pressure evenly across the vessel's end.
Hemispherical Head: A hemispherical head is a rounded vessel end that has a shape similar to half of a sphere. It is commonly used in high-pressure applications, such as oil and gas tanks, because its curved shape allows for better pressure distribution and reduced stress concentration.
Elliptical Dished End: An elliptical dished end, as the name suggests, has an elliptical shape. It is another type of curved vessel end used in pressure vessels and tanks. The elliptical shape offers a compromise between the strength of a dish head and the pressure distribution of a hemispherical head.
Oil and gas tanks often require pressure vessel heads that can handle high-pressure environments, which is why materials like ASME SA516 GR.70 are commonly used. It is crucial to follow applicable codes and standards, such as the ASME Boiler and Pressure Vessel Code, when designing, fabricating, and inspecting these components to ensure their safety and compliance with industry regulations.
