API Std 650 unanchored liquid-storage tanks formulas

Design of a Double-wall Tank
The outer bottom, shell, and roof of a double-wall tank shall enclose an insulating space around the bottom, shell, and roof or insulation deck of the inner tank that contains the stored liquid. The annular space shall be maintained at a low positive pressure, which necessitates that the enclosure be vapor-tight. The Purchaser shall specify the design metal temperature and pressure of the inner tank and may specify the design temperature and pressure of the outer tank API Std 650 unanchored liquid-storage tanks. The Purchaser shall state the specific gravity of the content to be stored, roof live loads, wind load, earthquake load where applicable, and corrosion allowance, if any.

The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API Std 650 unanchored liquid-storage tanks steel plate reaches the standard and the service life is longer.

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the API Std 650 unanchored liquid-storage tanks project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.

The establishment of a correct method for evaluating the life of API Std 650 unanchored liquid-storage tanks requires the preparation of criteria related to the strength and cracks of API Std 650 unanchored liquid-storage tanks, mechanical damage mechanisms, corrosion mechanisms, and mathematical models of fatigue crack growth, etc., which are compiled into computer programs. In the process of programming the program, it is required to select the operating parameters, plates, reinforcement accessories, metal properties, corrosion levels, mechanical damage defects and other data of the oil storage tank under various conditions.

The results of adopting two-level API Std 650 unanchored liquid-storage tanks service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and API Std 650 unanchored liquid-storage tanks after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
