API standard 650 ground-supported liquid storage tanks automatic bleeder vent

API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API standard 650 ground-supported liquid storage tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.

As a leading international API standard 650 ground-supported 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.

The Charpy V-notch test shall be used, and the minimum impact value at the design metal temperature shall be as given in Table R-2. For subsize specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 welded storage tanks Manufacturer, but in such a case the impact values at the test temperature must comply with Table R-2.

Anti corrosion of API standard 650 ground-supported liquid storage tanks:
After using for a certain period of time, it is necessary to check the corrosion protection of the API standard 650 ground-supported liquid storage tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API standard 650 ground-supported liquid storage tanks does not fall off and has good waterproof and rust resistance.
API standard 650 ground-supported liquid storage tanks cleaning:
The long-term use of API standard 650 ground-supported liquid storage tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API standard 650 ground-supported liquid storage tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.
