API Std 650 welded storage tanks for petroleum products storage

The cost of mechanical cleaning for vertical storage tank, API Std 650 welded storage 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 Std 650 welded storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API Std 650 welded storage 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.

Except as permitted by API standard 620 Q.8.6, the test shall be conducted after the entire tank is complete, before the insulation is applied. Except as limited by foundation or stress conditions, the test shall consist of filling the tank with water to the design liquid level and applying an overload air pressure of 1.25 times the pressure for which the vapor space is designed. The load on the supporting foundation shall preferably not exceed the established allowable bearing value for the tank site. Where a thorough evaluation of the foundation justifies a temporary increase, the established allowable bearing may be increased for the test condition, but the increase shall be not more than 25%.

API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 welded storage tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
