An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API Std 650 unanchored tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API Std 650 unanchored tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.[Enterprise Spirit]: professional, honest, dedicated and innovative.[Enterprise Tenet]: provide customers with satisfactory steel products and services.[Enterprise Policy]: customer satisfaction is our pursuit.

Vertical internal floating roof API Std 650 unanchored tanks has both dome roof and internal floating roof. The internal floating roof floats on the liquid surface inside the dome roof oil tank and can float up and down. The storage capacity is usually between 1000 and 10000 cubic meters.
