5083 aluminum forgings API standard 650 aboveground petroleum storage tanks

The ring of API standard 650 aboveground petroleum storage tanks annular plates shall have a circular outside circumference, but may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with API Standard 620 R.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by welds as required by API Standard 620 5.9.5 except when a full penetration weld is used or required.

API 650 only covers tanks that support the whole bottom evenly and API standard 650 aboveground petroleum storage tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.

In year 2015, we supplied 950 tons S355J0 angle steel to Egypt government. We have cooperation with local government for more than 3 years. Every year, they would order more than 3000 tons of API standard 650 aboveground petroleum storage tanks steel from our company.

Atmospheric API standard 650 aboveground petroleum storage tanks refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API standard 650 aboveground petroleum storage tanks usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.
