1060 aluminum rod API standard 650 self-anchored flat-bottom tanks

Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

Before pressure testing, thoroughly flush the API 650 tank floating roof primary drain hose system. Supply API standard 650 self-anchored flat-bottom tanks blind flanges, gaskets, and bolting (for other types of blanking covers as may be required) necessary for testing.

Usually, the wind load in the API standard 650 self-anchored flat-bottom tanks construction area should be considered before the tank design and construction. The wind load in the API standard 650 self-anchored flat-bottom tanks construction area has an impact on the stability and economy of the API standard 650 self-anchored flat-bottom tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API standard 650 self-anchored flat-bottom tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
