single-deck pontoon-type floating roof API Std 650 partially anchored liquid-storage tanks

To scientifically evaluate the remaining service life of the API Std 650 partially anchored liquid-storage tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API Std 650 partially anchored liquid-storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API Std 650 partially anchored liquid-storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

The API Std 650 partially anchored liquid-storage tanks shell that contains the liquid shall have butt-welded annular bottom plates with a radial width that provides at least 24 in. between the inside of the shell and any lap-welded joint in the remainder of the bottom and at least a 2-in. projection outside the shell. The stated values apply to full-sized specimens. For sub-size specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 large welded, low pressure storage tanks Manufacturer.

The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API Std 650 partially anchored liquid-storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.

As a leading international API Std 650 partially anchored liquid-storage tanks steel supplier, we have two warehouses, close to Tianjin port and Shanghai port. This superior geographical location effectively saves the domestic transportation cost and greatly improves our service level. At the same time, it also shortens our delivery time and provides more convenience for customers.
