5456 aluminum shapes API 650 aluminum tanks

The cost of mechanical cleaning for vertical storage tank, API 650 aluminum tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API 650 aluminum tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API 650 aluminum tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.

Charpy V-notch specimens shall be taken from the weld metal and from the heat-affected zone of the welding procedure qualification test plates or from duplicate test plates.
Weld metal impact specimens shall be taken across the weld with the notch in the API 620 oil tank material weld metal. The specimen shall be oriented so that the notch is normal to the surface of the material. One face of the specimen shall be substantially parallel to and within 1/16 in. of the surface.

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API 650 aluminum tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
