ASTM A516 Gr.70 Carbon Steel Elliptical Head / Ellipsoidal Dish End For Oil Gas Tanks


ASTM A516 Gr.70 carbon steel elliptical heads, also known as ellipsoidal dish ends, are specific components used in the construction of oil and gas tanks. Here's some information about these components:

  1. ASTM A516 Gr.70: ASTM A516 Gr.70 is a specification established by the American Society for Testing and Materials (ASTM) that covers standards for carbon steel plates used for pressure vessel applications. A516 Gr.70 is a commonly used grade due to its excellent mechanical properties, including high strength, good weldability, and moderate corrosion resistance.

  2. Elliptical Head/Ellipsoidal Dish End: An elliptical head or ellipsoidal dish end is a curved vessel end that has an elliptical shape. It is often used in the construction of tanks and pressure vessels, including oil and gas tanks. The elliptical shape provides structural stability and helps distribute pressure evenly across the tank or vessel. Elliptical heads/ellipsoidal dish ends are specifically designed to optimize pressure distribution and reduce stress concentrations.

When using ASTM A516 Gr.70 carbon steel for elliptical heads/ellipsoidal dish ends in oil and gas tanks, it combines the benefits of carbon steel, such as strength and weldability, with the specific head shape designed for efficient pressure containment and structural integrity.


It is important to follow industry standards and codes, such as API 650 for welded oil storage tanks and ASME Boiler and Pressure Vessel Code, when designing, fabricating, and inspecting oil and gas tanks with ASTM A516 Gr.70 elliptical heads/ellipsoidal dish ends. Adhering to these standards ensures the tanks meet the necessary quality and safety requirements for storing oil and gas effectively.
