Carbon steels, such as ASTM A131 4 steels, have occasionally been used in storage tank construction. Another carbon steel with specified chemical composition to provide better weldability is ASTM A36. This grade is now being used in water stor-age tanks.
Atmospheric Storage Tanks are an integral part of any refinery or process plants as they are used to store fluids for various purposes for short or long duration. Feedstock tanks and product tanks provide buffer capacity between process plants, which are generally in continuous operation, and the supply/dispatch of feedstock/products, which are batch operations in general.
